IO error I've never seen before....

[Mona Buck]

This one's new to me. When I try to do an ls on the /var/adm/sw/products/make directory, I get ". not found" and on my backups, I am getting "IO error" when it tries to access the directory. I can't remove it, I can't look in it, I can't chmod it, zip. Any ideas?

TIA, Mona

Look like you have a hardware problem (disk). Unmount the file system and check it with:
# fsck

Check the disk which is holding the file system with:
# dd
# stm

If errors found, then replace it with new disk

Hi Mona!

Is this an NFS mount? It has symptoms of an NFS mount gone awry.

What is the uptime on the box? It may be necessary for a fsck on the filesystem if it isn't an NFS.

HTH,

It sounds like it it time to run fsck on the file system.

Perhaps the directory entry has some strange characters.... try to rename from the X-Windows File Browser...

or to do something like this

# for i in $(ls /var/adm/sw/products | grep "*[m]*[a]*[k]*[e]*")
>do
>mv /var/adm/sw/products/$i /var/adm/sw/products/make
>done

I can't take the box down unless there's no alternative; I tried to mirror it off, and then split the mirrors, but it says there are stale extents on c1t3d0. This box reboots every night, so I guess I know what I'll be doing tomorrow morning....at least I've narrowed it down to a single disk. Thanks for all your help!

2 suggestions:

1. Find the disk(s) that belongs to the volume group of the mounted filesytems and run a pvdisplay and a diskinfo on it. Also check the volume group and make sure PV and Active PV #'s match.

2. Unmount the filesystem and then check the parent directory to see if you get the directory entry. CD into the mount directory (while it is unmounted) and check "ls -l". You should get . and .. If you don't, see #1 for base directory problems.
