Hi Neil! Thanks much for the patch, the array can now be started again. However, I observe some strange behaviour with raid1 intelligent resync. I'm not sure if your new patch (md/raid1: clear bitmap when fullsync completes) http://marc.theaimsgroup.com/?l=linux-raid&m=112140143401678&w=2 addresses this strangeness, cause I still didn't apply it. When we create a raid1 array with bitmap it starts a full resync. Let's wait a couple of minutes, so the resync will proceed to, say, 50%. Then stop the array and assemble it again with the same bitmap. We expect it should resync only the remaining part, but it does a full resync again instead. Please see a log below. What do you think? Thanks, Maxim Kozover. # mdadm -C /dev/md0 --bitmap /bitmap -e 1 -l 1 -n 2 /dev/sdb /dev/sdc mdadm: array /dev/md0 started. # more /proc/mdstat Personalities : [raid1] md0 : active raid1 sdc[1] sdb[0] 16777208 blocks [2/2] [UU] [===========>.........] resync = 55.6% (9339328/16777208) finish=4.2min speed=29091K/sec bitmap: 2048/2048 pages [8192KB], 4KB chunk, file: /bitmap unused devices: <none> # mdadm -S /dev/md0 # mdadm -A /dev/md0 --bitmap /bitmap /dev/sdb /dev/sdc mdadm: /dev/md0 has been started with 2 drives. # more /proc/mdstat Personalities : [raid1] md0 : active raid1 sdb[0] sdc[1] 16777208 blocks [2/2] [UU] [>....................] resync = 0.3% (53248/16777208) finish=5.2min spe ed=53248K/sec bitmap: 2048/2048 pages [8192KB], 4KB chunk, file: /bitmap unused devices: <none> MK> Thanks much, Neil, will try.
