Subject: raid1: resync hanging until reboot
Date: Mon, 07 Apr 2003 15:25:14 +0200 [thread overview]
Message-ID: <3.0.6.32.20030407152514.00b8ae30@athen> (raw)
Hello!
When we disable a partition from a raid meta device
and try to reattach it again without a reboot in between
the resynch often starts hanging. After a reboot the
resynch does complete. In detail:
We use Linux version 2.4.19-64GB-SMP
We create a raid1 meta devivce:
mdadm -Cv /dev/md0 -l1 -n2 /dev/sda1 /dev/sdb1
We disable one piece from the meta device:
mdadm /dev/md0 -f /dev/sda1 -r /dev/sda1
We reattach it to the meta device:
mdadm /dev/md0 -a /dev/sda1
And very often but not always the resych hangs with
cat /proc/mdstat showing:
md0 : active raid1 sda1[2] sdb1[1]
80256 blocks [2/1] [_U]
[>....................] recovery = 0.0% (0/80256) finish=26.7min
speed=0K/sec
Does anybody know a solution to this problem?
Thank you very much
Alfred
