It is resyncing to hdi1. It should be done around 2:00 your time. You could up the speed! Do this: echo 100000 > /proc/sys/dev/raid/speed_limit_max Then note the speed increase with: cat /proc/mdstat Guy -----Original Message----- From: linux-raid-owner@xxxxxxxxxxxxxxx [mailto:linux-raid-owner@xxxxxxxxxxxxxxx] On Behalf Of Sharif Islam Sent: Wednesday, January 05, 2005 12:51 PM To: linux-raid@xxxxxxxxxxxxxxx Subject: Confusing failed disk situation I am rebuilding a RAID-5 with 5 disk. Last night when it finished I saw the RAID is done with one failed disk. Not sure what happened. It gave me inode error on mke2fs. Then I replaced the failed disk(hdi) with another old disk. I am pretty sure both disks are fine. I noticed this.
