Not what you want to see when rebuilding the RAID1 array from hda to hdc:

Jan 18 13:42:12 009027cafcca kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
Jan 18 13:42:12 009027cafcca kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=26824299, sector=26824159
Jan 18 13:42:12 009027cafcca kernel: end_request: I/O error, dev hda, sector 26824159
Jan 18 13:42:12 009027cafcca kernel: raid1: hdc: unrecoverable I/O read error for block 24574240

and of course this is /dev/md2, serving what you might ask? Of course! :

[root@009027cafcca root]# grep /dev/md2 /etc/fstab 
/dev/md2 / ext3 defaults 1 1

and the best part – where in the rebuild this occurs:

md2 : active raid1 hda6[0] hdc6[2]
      12287424 blocks [2/1] [U_]
      [===================>.]  recovery = 99.8% (12268672/12287424) finish=0.0min speed=12697K/sec

Did I mention this is on the webserver/mailserver/blogger/gateway/firewall, etc etc computer? Damn you Murphy! The good news is that none of my files are affected, it is just the RAID1 rebuild.

Well, off to mandrake to download the latest CDs. Luckily I do have a spare drive I can place in that machine.
