(apologies in advance if this silly hotmail account adds any HTML..)
I have a 4.8-RELEASE server running stock Generic kernal as a NFS and samba
file server. It's got a pile of standard IDE discs in it, 40 to 120Gb each,
using two third party PCI IDE cards.
Within the last couple of weeks I have now had three hard disc go down -
symptoms are basically that any access to the directories hosted on that
drive gives a "device not configured" error. Indeed anything trying to
access the drive gives the same error. even umount gives the same error...
a quick grep of the logs turns up:
Oct 5 03:03:29 luggage /kernel: ad3: READ command timeout tag=0 serv=0 -
Oct 5 03:03:29 luggage /kernel: ata1: resetting devices ..
Oct 5 03:03:29 luggage /kernel: ad3: removed from configuration
Oct 5 03:03:29 luggage /kernel: done
Firsttly, and most important, is there anything I can do to restore the
drive? A reboot didn't ... There's not much in the top level directory of
each drive, but loads in sub-folders. They are not accessed much, but I
don't particularly want to lose the data. One of them is my backup drive,
What would you recommend to avoid problems in the future? I think it's time
to build a new server anyway (this is only an AMD K6 2/500) - Would it be
best to run a RAID filesystem, and would 1+0 be better than RAID5 for
reslilence on future failures? Is this reliable on cheap IDE drives?
Thanks in advance,
