| * | [SERVER] Use O_DIRECT for integrity checks | Simon Rettberg | 2018-07-04 | 1 | -26/+55 |
| | | | | | | | | | | | | | | | The idea is that for full image checks, we don't want to pollute the fs cache with gigabytes of data that won't be needed again soon. This would certainly hurt performance on servers that dont have hundreds of GBs of RAM. For single block checks during replication this has the advantage that we don't check the block in memory before it hit the disk once, but actually flush the data to disk, then remove it from the page cache, and only then read it again, from disk. TODO: Might be worth making this a config option | ||||
| * | [SERVER] Refactor uplink/cache handling, improve crc checking | Simon Rettberg | 2018-07-04 | 1 | -12/+76 |
| | | | | | | | | | | | | | | The cacheFd is now moved to the uplink data structure and will only be handled by the uplink thread. The integrity checker now supports checking all blocks of an image. This will be triggered automatically whenever a check for a single block failed. Also, if a crc check on startup fails, the image won't be discarded anymore, but rather a full check will be initiated. Furthermore, when calling image_updateCacheMap() on an image that was previously complete, the cache map will now be re-initialized, and a new uplink connection created. | ||||

| * | [SERVER] BREAKING: Get rid of pseudo case-insensitivityv2.1 | Simon Rettberg | 2016-02-01 | 1 | -1/+1 |
| | | | | | | | | | | | This was a wrong decision made long time ago, and it's broken in certain scenarios (eg. two servers serving from same NFS mount). Also it's of limited use anyways since it only supportes ASCII and would ignore umlauts, so blöd and BLÖD would still be considered two different images. So if you relied on this "feature" in any way, be careful when updating. | ||||
