I pulled out 4 disks, and using raidhotadd I triggered a rebuild on 3 of them. While rebuilding md1, the rebuilding process is stuck at 0.0%. Below is a snapshot of "/proc/mdstat". ----- md1 : active raid1 sdi2[12] sdh2[11] sdg2[10] sde2[4] sdd2[1] sdc2[0] sdb2[2] sda2[5] 405504 blocks [9/5] [UUU_UU___] [>....................] recovery = 0.0% (384/405504) finish=176649.2min speed=0K/sec ----- The finish="***" time is increasing constantly. (1) What may be the cause. I have experienced it several times. There is no heavy IO going-on on any of the partitions. Machine is kind of idle. (2) Can we somehow stop the rebuilding process and restart it again? (3) Rebooting will fix it. But I am trying to find a better solution. Any help is highly appreciated.
