If your only concern is the re-sync, then no problem. An array is usable while it is re-syncing. However, I don't know why it is re-syncing. Maybe the failed attempt to start the array is at fault. I don't know if this is normal or not.

Sigh, I'm having what might be xfs/nfsd conflicts and thought I'd reboot into an old 2.6.6 kernel which used to be stable. Of course it spotted the fd partitions and tried to start the array. It failed (the old kernel didn't have a driver for the new controller so some devices were missing) However when I came back to 2.6.9 I get the rather conflicting status shown below. It already mounted (xfs) but I unmounted quite quickly. Can this do any harm? Should I leave it to complete? Can I safely remount? My worry is that the kernel and mdadm think all the devices are 'up' and so may write to them and upset the resync (I suspect it thinks /dev/sdf1 is dirty since that wasn't there under 2.6.6) cu:~# mdadm --detail /dev/md0 /dev/md0: Version : 00.90.01 Creation Time : Sun Nov 21 21:36:49 2004 Raid Level : raid5 Array Size : 1225543680 (1168.77 GiB 1254.96 GB) Device Size : 245108736 (233.75 GiB 250.99 GB) Raid Devices : 6 Total Devices : 7 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Thu Nov 25 12:51:46 2004 State : dirty, resyncing Active Devices : 6 Working Devices : 7 Failed Devices : 0 Spare Devices : 1 Layout : left-symmetric Chunk Size : 4096K Rebuild Status : 0% complete UUID : 44e121b0:6e3422b0:4d67f451:51df5ae0 Events : 0.35500 Number Major Minor RaidDevice State 0 8 1 0 active sync /dev/sda1 1 8 17 1 active sync /dev/sdb1 2 8 33 2 active sync /dev/sdc1 3 8 49 3 active sync /dev/sdd1 4 3 65 4 active sync /dev/hdb1 5 8 81 5 active sync /dev/sdf1 6 8 65 - spare /dev/sde1 cu:~# cu:~# cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid5] [raid6] md0 : active raid5 sdf1[5] sde1[6] sdd1[3] sdc1[2] sdb1[1] sda1[0] hdb1[4] 1225543680 blocks level 5, 4096k chunk, algorithm 2 [6/6] [UUUUUU] [>....................] resync = 0.3% (905600/245108736) finish=304.3min speed=13369K/sec unused devices: <none> - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
