* md/raid10: handle recovery of replacement devices.NeilBrown2011-12-231-30/+80
| | | | | | | If there is a replacement device, then recover to it, reading from any drives - maybe the one being replaced, maybe not. Signed-off-by: NeilBrown <neilb@suse.de>
* md/raid10: Handle replacement devices during resync.NeilBrown2011-12-231-7/+98
| | | | | | | | | | | | If we need to resync an array which has replacement devices, we always write any block checked to every replacement. If the resync was bitmap-based resync we will then complete the replacement normally. If it was a full resync, we mark the replacements as fully recovered when the resync finishes so no further recovery is needed. Signed-off-by: NeilBrown <neilb@suse.de>
* md/raid10: writes should get directed to replacement as well as original.NeilBrown2011-12-231-9/+74
| | | | | | | | | | | | | | When writing, we need to submit two writes, one to the original, and one to the replacements - if there is a replacement. If the write to the replacement results in a write error we just fail the device. We only try to record write errors to the original. This only handles writing new data. Writing for resync/recovery will come later. Signed-off-by: NeilBrown <neilb@suse.de>

* md/raid10: preferentially read from replacement device if possible.NeilBrown2011-12-231-13/+23
| | | | | | | | | When reading (for array reads, not for recovery etc) we read from the replacement device if it has recovered far enough. This requires storing the chosen rdev in the 'r10_bio' so we can make sure to drop the ref on the right device when the read finishes. Signed-off-by: NeilBrown <neilb@suse.de>
* md/raid10: change read_balance to return an rdevNeilBrown2011-12-231-14/+13Star
| | | | | | | | | | | It makes more sense to return an rdev than just an index as read_balance() gets a reference to the rdev and so returning the pointer make this more idiomatic. This will be needed in a future patch when we might return a 'replacement' rdev instead of the main rdev. Signed-off-by: NeilBrown <neilb@suse.de>

| | | | | | | | | | Allow each slot in the RAID10 to have 2 devices, the want_replacement and the replacement. Also an r10bio to have 2 bios, and for resync/recovery allocate the second bio if there are any replacement devices. Signed-off-by: NeilBrown <neilb@suse.de>
* md/raid5: Mark device want_replacement when we see a write error.NeilBrown2011-12-231-0/+3
| | | | | | | | | | | Now that WantReplacement drives are replaced cleanly, mark a drive as WantReplacement when we see a write error. It might get failed soon so the WantReplacement flag is irrelevant, but if the write error is recorded in the bad block log, we still want to activate any spare that might be available.

| | | | | | | | | | | When attempting to add a spare to a RAID[456] array, also consider adding it as a replacement for a want_replacement device.

* md/raid5: handle activation of replacement device when recovery completes.NeilBrown2011-12-231-7/+62
| | | | | | | | | | | | | | | | When recovery completes - as reported by a call to ->spare_active, we clear In_sync on the original and set it on the replacement. Then when the original gets removed we move the replacement from 'replacement' to 'rdev'. This could race with other code that is looking at these pointers, so we use memory barriers and careful ordering to ensure that a reader might see one device twice, but never no devices. Then the readers guard against using both devices, which could only happen when writing. Signed-off-by: NeilBrown <neilb@suse.de>
* md/raid5: detect and handle replacements during recovery.NeilBrown2011-12-232-30/+106
| | | | | | | | | | | | | | | | | | | During recovery we want to write to the replacement but not the original. So we have two new flags - R5_NeedReplace if this stripe has a replacement that needs to be written at some stage - R5_WantReplace if NeedReplace, and the data is available, and a 'sync' has been requested on this stripe. We also distinguish between 'sync and replace' which need to read all other devices, and 'replace' which only needs to read the devices being replaced. Note that during resync we always write to any replacement device. It might not need to be written to, but as we don't read to compare, we have to write to be sure.

* md/raid5: preferentially read from replacement device if possible.NeilBrown2011-12-231-15/+54
| | | | | | | | | | | | | | | | If a replacement device is present and has been recovered far enough, then use it for reading into the stripe cache. If we get an error we don't try to repair it, we just fail the device. A replacement device that gives errors does not sound sensible. This requires removing the setting of R5_ReadError when we get a read error during a read that bypasses the cache. It was probably a bad idea anyway as we don't know that every block in the read caused an error, and it could cause ReadError to be set for the replacement device, which is bad.

* md/raid5: allow each slot to have an extra replacement deviceNeilBrown2011-12-232-26/+46
| | | | | | | | | | | | | | | | | | | Just enhance data structures to record a second device per slot to be used as a 'replacement' device, replacing the original. We also have a second bio in each slot in each stripe_head. This will only be used when writing to the array - we need to write to both the original and the replacement at the same time, so will need two bios. For now, only try using the replacement drive for aligned-reads. In this case, we prefer the replacement if it has been recovered far enough, otherwise use the original. This includes a small enhancement. Previously we would only do aligned reads if the target device was fully recovered. Now we also do them if it has recovered far enough.

* md: create externally visible flags for supporting hot-replace.NeilBrown2011-12-234-39/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | hot-replace is a feature being added to md which will allow a device to be replaced without removing it from the array first. With hot-replace a spare can be activated and recovery can start while the original device is still in place, thus allowing a transition from an unreliable device to a reliable device without leaving the array degraded during the transition. It can also be use when the original device is still reliable but it not wanted for some reason. This will eventually be supported in RAID4/5/6 and RAID10. This patch adds a super-block flag to distinguish the replacement device. If an old kernel sees this flag it will reject the device. It also adds two per-device flags which are viewable and settable via sysfs. "want_replacement" can be set to request that a device be replaced. "replacement" is set to show that this device is replacing another device. The "rd%d" links in /sys/block/mdXx/md only apply to the original device, not the replacement. We currently don't make links for the replacement - there doesn't seem to be a need. Signed-off-by: NeilBrown <neilb@suse.de>

We then call into the personality's hot_add_disk function which performs the same test and returns the same error. Thus the common test is not needed. As we will shortly be changing some personalities to allow duplicates in some cases (to support hot-replace), the common test will become inconvenient. So remove the common test.

* md/bitmap: be more consistent when setting new bits in memory bitmap.NeilBrown2011-12-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | For each active region corresponding to a bit in the bitmap with have a 14bit counter (and some flags). This counts number of active writes + bit in the on-disk bitmap + delay-needed. The "delay-needed" is because we always want a delay before clearing a bit. So the number here is normally number of active writes plus 2. If there have been no writes for a while, we drop to 1. If still no writes we clear the bit and drop to 0. So for consistency, when setting bit from the on-disk bitmap or by request from user-space it is best to set the counter to '2' to start with. In particular we might also set the NEEDED_MASK flag at this time, and in all other cases NEEDED_MASK is only set when the counter is 2 or more. Signed-off-by: NeilBrown <neilb@suse.de>

* md/raid5: be more thorough in calculating 'degraded' value.NeilBrown2011-12-231-30/+33
| | | | | | | | | | | | | | | | When an array is being reshaped to change the number of devices, the two halves can be differently degraded. e.g. one could be missing a device and the other not. So we need to be more careful about calculating the 'degraded' attribute. Instead of just inc/dec at appropriate times, perform a full re-calculation examining both possible cases. This doesn't happen often so it not a big cost, and we already have most of the code to do it. Signed-off-by: NeilBrown <neilb@suse.de>

* md/bitmap: It is OK to clear bits during recovery.NeilBrown2011-12-221-4/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit d0a4bb492772ce5c4bdfba3744a99ed6f6fb238f introduced a regression which is annoying but fairly harmless. When writing to an array that is undergoing recovery (a spare in being integrated into the array), writing to the array will set bits in the bitmap, but they will not be cleared when the write completes. For bits covering areas that have not been recovered yet this is not a problem as the recovery will clear the bits. However bits set in already-recovered region will stay set and never be cleared. This doesn't risk data integrity. The only negatives are: - next time there is a crash, more resyncing than necessary will be done. - the bitmap doesn't look clean, which is confusing. While an array is recovering we don't want to update the 'events_cleared' setting in the bitmap but we do still want to clear bits that have very recently been set - providing they were written to the recovering device. So split those two needs - which previously both depended on 'success' and always clear the bit of the write went to all devices. Signed-off-by: NeilBrown <neilb@suse.de>
* md: don't give up looking for spares on first failure-to-addNeilBrown2011-12-221-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | Before performing a recovery we try to remove any spares that might not be working, then add any that might have become relevant. Currently we abort on the first spare that cannot be added. This is a false optimisation. It is conceivable that - depending on rules in the personality - a subsequent spare might be accepted. Also the loop does other things like count the available spares and reset the 'recovery_offset' value. If we abort early these might not happen properly. So remove the early abort. In particular if you have an array what is undergoing recovery and which has extra spares, then the recovery may not restart after as reboot as the could of 'spares' might end up as zero.

| | | | | | | | | | | | | | | commit d70ed2e4fafdbef0800e73942482bb075c21578b broke hot-add to a linear array. After that commit, metadata if not written to devices until they have been fully integrated into the array as determined by saved_raid_disk.

* md: take a reference to mddev during sysfs access.NeilBrown2011-12-081-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we are accessing an mddev via sysfs we know that the mddev cannot disappear because it has an embedded kobj which is refcounted by sysfs. And we also take the mddev_lock. However this is not enough. The final mddev_put could have been called and the mddev_delayed_delete is waiting for sysfs to let go so it can destroy the kobj and mddev. In this state there are a lot of changes that should not be attempted. To to guard against this we: - initialise mddev->all_mddevs in on last put so the state can be easily detected. - in md_attr_show and md_attr_store, check ->all_mddevs under all_mddevs_lock and mddev_get the mddev if it still appears to be active. This means that if we get to sysfs as the mddev is being deleted we will get -EBUSY. rdev_attr_store and rdev_attr_show are similar but already have sufficient protection. They check that rdev->mddev still points to mddev after taking mddev_lock. As this is cleared before delayed removal which can only be requested under the mddev_lock, this ensure the rdev and mddev are still alive. Signed-off-by: NeilBrown <neilb@suse.de>
* md: refine interpretation of "hold_active == UNTIL_IOCTL".NeilBrown2011-12-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We like md devices to disappear when they really are not needed. However it is not possible to tell from the current state whether it is needed or not. We can only tell from recent history of changes. In particular immediately after we create an md device it looks very similar to immediately after we have finished with it. So we always preserve a newly created md device until something significant happens. This state is stored in 'hold_active'. The normal case is to keep it until an ioctl happens, as that will normally either activate it, or explicitly de-activate it. If it doesn't then it was probably created by mistake and it is now time to get rid of it. We can also modify an array via sysfs (instead of via ioctl) and we currently treat any change via sysfs like an ioctl as a sign that if it now isn't more active, it should be destroyed. However this is not appropriate as changes made via sysfs are more gradual so we should look for a more definitive change. So this patch only clears 'hold_active' from UNTIL_IOCTL to clear when the array_state is changed via sysfs. Other changes via sysfs are ignored. Signed-off-by: NeilBrown <neilb@suse.de>
* md/lock: ensure updates to page_attrs are properly locked.NeilBrown2011-11-231-0/+4
| | | | | | | | | | | | | | | | | Page attributes are set using __set_bit rather than set_bit as it normally called under a spinlock so the extra atomicity is not needed. However there are two places where we might set or clear page attributes without holding the spinlock. So add the spinlock in those cases.

| * | ARM: OMAP1: Fix warnings about enabling 32 KiHz timerTony Lindgren2011-11-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fix "Enable 32kHz OS timer in order to allow sleep states in idle" warning. We are now compiling in bothe MPU timer and 32 KiHz timer, so this warning is only valid when MPU_TIMER is set and OMAP_DM_TIMER is not set. Signed-off-by: Tony Lindgren <tony@atomide.com>

A warning was added to highlight and thus fix the redundancy.
