I am running RedHat 7.0 and have two 30 GB drives, hda and hdc, with
identical partitions configured as RAID 1. Yesterday, after a sytem
lockup, I did a hard boot. I didn't pay close enough attention and
didn't realize that the second drive (hdc) did not come back online.
I then proceded to incorrectly specify a raidhotadd as
raidhotadd /dev/md1 /dev/hdc
Oops, that trashed my partition table on hdc. After reconstructing
the partition table I proceded to *correctly* to a raidhotadd of all
the partitions. Unfortunately, it would appear that hda is having
real hardware problems. All partitions have resynced except one, and
I am getting persistent hardware errors from the drive.
Below is a sample error message.
How can I get past this? I can't sync the second drive because of the
hardware problem; the resync keeps looping. I expect that even when I
finally get the replacement drive I'm hosed. Any suggestions?
