Changes will remain in memory only, until you decide to write them. Be careful before using the write command. GPT PMBR size mismatch (20479 != 40959) will be corrected by write. The backup GPT table is not on the end of the device. This problem will be corrected by write. Command (m for help): Partition number (2-128, default 2): First sector (20447-40926, default 20480): Last sector, +/-sectors or +/-size{K,M,G,T,P} (20480-40926, default 40926): Created a new . Command (m for help): The partition table has been altered. Calling ioctl() to re-read partition table. Re-reading the partition table failed.: Invalid argument The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or partx(8). ----- list result: ----- Disk : 20 MiB, 20971520 bytes, 40960 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / bytes Disklabel type: gpt Disk identifier: Device Start End Sectors Size Type p1 2048 20446 18399 9M Linux filesystem p2 20480 40926 20447 10M Linux filesystem
