Was wondering is someone could help me out here.

One of our AIX servers is running version 4.2.1 - Yes I know, very old!

Our backups use the mksysb command as follows:
mksysb -i -X /dev/rmt0

Checking the logfile this morning I see the following:
Creating information file (/image.data) for rootvg.....
Creating tape boot image ...
Creating list of files to back up .find: cannot chdir to </usr/include/rpcsvc> : I/O error.

When trying to check out the problem, I get the following:

1. cd /usr/include/rpcsvc
2. ls

. not found

Could anyone help?

That doesn't look good. When was the last time you booted the box?
It looks like you might have a corrupted /usr somehow. You may want
to boot your box to maintenance mode and run fsck on /usr. While you
were there, run fsck on all FS in rootvg just to be safe.

Orphy,

No it doesnt look good does it? Plus it's stopping our backup from running every night.

I've tried rebooting the box several times and there are no errors.
I tried changing the check parameter in /etc/filesystems to true and then reboot but still no errors.
I cannot run a manual fsck on the /usr filesystem even from maintenance mode due to it being mounted and I cannot unmount it because it says it is in use.
I would have thought also that if I was able to unmount the /usr filesystem that most of the commands (including fsck) which reside under /usr will not be available. Or will they?

Any ideas?

You should be able to fsck /usr in maintenance mode but you need to
pick Option 2 to access rootvg. In fact, I had to recover from a 552
recently but I hadn't had to fix 552 for years.

You seem to know what you are doing but be sure you don't perform every
step of this procedure. All you should need is to get to the fsck (step 4).
However, you might as well want to do "mount /dev/hd2 /mnt/usr" and check
to see if your "corrupted" directory is there.

fsck from there typically fix 99.9% of the corruptions. If you still
got problem, it could be a bug and maybe you need an APAR or something.

Can't thank you enough for your help on this.

I managed to boot off one of our recent mksysb backup tapes, get it to the unix prompt, run the fsck -p /dev/hd2 which picked up the problem and fixed it in one full swoop.
I then mounted the partition in /mnt and check that directory and there were all the files.
After rebooting the server, checked the directory and still good.

I am WELL pleased.

Thanks again.
