Joe,

Check this doc.

Is /depot a filesystem?

# lvdisplay -v /dev/vgxx/lvolx

check if the disks report i/o errors.

# dd if=/dev/rdsk/cxtydz of=/dev/null bs=1024k

Regards,

infact i can write to other directories under /depot. the error i get is only for /depot/data directory (No such device or address).

Thx

Joe,
may be inode corruption. What does fsck report?

What version of HP-UX and what version of JFS are these filesystems?

You may need to look into some patches if you are on HP-UX 11.0 and JFS 3.1 or JFS 3.3.

PHKL_24014 (HP-UX 11.0 & JFS 3.1) - http://www1.itrc.hp.com/service/cki/patchDocDisplay.do?patchId=PHKL_24014

Yes agreed you can write to directory /depot/data - but directory seems to be a directory in /depot filesystem and not a seperate filesystem in itself.
I would advice you to unmount the /depot filesystem and do a fsck on it
fsck -F vxfs -o full /dev/....

Hello Joe

This problem is for inode curruption,hence you have couple of option.

either delete file or directory which has inode 12 or

best option is

unmount the filesystem.

execute full filesystem check

fsck with -o option ..

then mount filesystem again

and check lost+found directory for result.

second option will definatly work.
