A few weeks back some folks helped me with an apparantly bad WD 1.6G hard
drive. I was getting errors such as:
>Oct 24 23:41:42 spock kernel: hda: read_intr: status=0x59 {
DriveReady SeekComp
>lete DataRequest Error }
>Oct 24 23:41:42 spock kernel: hda: read_intr: error=0x40 {
UncorrectableError }
...and so on
The consensus was either a bad drive or corrupted partition table. Since
then I have had no problems, until yesteday. Now, here is the
interesting (to me anyway) part. I feel it is an NFS issue, and the drive
is fine. Allow me to explain.
The machine in question is a headless server. It's most stressful use is
as an NFS server, while handling light SMB, mail, and http proxy duties.
EACH time I had the kernel panics I was manipulating files via NFS. Now,
the the juicy part:
Yesterday I had to re-address the entire network (changes upstream). I
changed the IP address on the server and a machine with an active /home
NFS mounted. Well, the client machine hung, and rebooting the server took
forever waiting for the time outs. When it booted it came into the
Repair# prompt, with the same error messages!! I fixed it with fsck -b
8193 /dev/hda4, rebooted cleanly.
So, I am pointing my finger at the Network File System. From the server,
here is /etc/exports:
/home/mitch 207.90.210.147(rw)
/mnt/cdrom (rw)
/ 207.90.210.147(rw)
/var/spool/mail/mitch 207.90.210.147(rw)
...and /etc/fstab:
/dev/hda3 / ext2 defaults 1 1
/dev/hda4 /home ext2 defaults 1 2
/dev/cdrom /mnt/cdrom iso9660 ro 0 0
/dev/fd0 /mnt/floppy ext2
defaults,noauto 0 0
/dev/hda1 /mnt/msdos msdos defaults 0 0
/proc /proc proc defaults
/dev/hda2 none swap sw
xxxxx.xxxxx.com:/home/mitch /home/mitch/mitch_snappy nfs intr
(name changed to protect the guilty)
And, from the client machine:
# /etc/fstab
/dev/hdb2 / ext2 defaults 1 1
/dev/hdb4 /home ext2 defaults 1 2
/dev/hdb3 /usr ext2 defaults 1 2
/dev/hda1 /mnt/msdos msdos user 1 2
/dev/sbpcd /mnt/cdrom iso9660 ro 0 0
# proc filesystem
/proc /proc proc defaults 0 0
/dev/fd0 /mnt/floppy ext2 defaults,noauto 0 0
# Swap partitions
/dev/hdb1 none swap sw
# NFS Filesystems
spock.mitch.color.net:/home/mitch /home/mitch nfs timeo=14,intr
# snappy.smithphoto.com:/home/mitch /home/mitch/mitch_snappy nfs
spock.mitch.color.net:/ /mnt/spock nfs timeo=14,intr
spock.mitch.color.net:/var/spool/mail/mitch /var/spool/mail/mitch nfs
timeo=14,intr
OK, sorry for the long post, but I figured all that might help. BTW,
these are two RH 3.0.3 machines, few patches. The server is a 486/66 and
the client is a P60 (with BUG).
Is there a problem with my NFS setup? Thanks for any suggestions.
