Running unattended fsadm for defragmenting vxfs file system

[Mark Waddington_2]

When running "fsadm -F vxfs -e /xx" we once had it abort when it ran on a file
system that was nearly full. The script will now check for file systems less
than 85% full.

Does anyone have any experience on how safe it is to run unattended during the
evenings and let us know if they have had problems.

Also are any backups recommended prior to it?


Thanks

We are running fsadm on a nightly basis at our site. The only check that the
script performs is to make sure that the filesystem is below 80% full.

Hi, we also have found no problem in automatically
defragmenting of filesystems. Nevertheless, we
backup prior to that as a precaution.
