several choices:
- you could problems with vquotacheck not having been run after a
crash. Solution: run vquotacheck on each file set when system is
idle or single user mode to see if this finds the space.
- fragmentation problems...run defragment to see if it helps
- frag file fragmentation ....need to run addvol/rmvol to see
if this fixes it (or vdump | vrestore)
I suggest you run sys_check on the system to give us more data

This customer has no quota activated and no advfs utilities to do
a defrag, so I asked for a vdump X vrestore.
Then another problem arised, because vdump ended up in error.
So I asked for a msfsck and it takes ours but finished.
Then backup was started again, this time it finished ours later.
But when trying to see its contents comes out a hardware error
message.
In fact there are no hardware error in this tape unit because it can
successfully work with other tapes from other system.
I found out a patch about a advfs problem with a heavy fragmented
file system, but I would like to be sure it can be applied in a machine with
Firewall, and if possible to find out if there is a script to do this
installation; I'm talking about patch OSF360-061 that is superseeded by
OSF360-067.
I sent also syscheck script to this customer and I'm waiting for the
output.
Thanks for you attention.

You need to run [v]quotacheck on reboot after a crash with advfs
regardless of whether you are enforcing quotas or not...it has to
do with advfs ALWAYS uses the quota data as part of its maintaing
in use/free space.

Do you need other patches (like for vdump or restore)...have you
checked all the patches for the release you are on (and installed them?)

you would have to ask support folks or advfs_support notes conference...
I don't know. I don't know of a patch fixing the existing problem...
you might want them to get the utiltities as addvol/rmvol is a
whole lot easier than vdump/vrestore.

I just received the output file of syscheck script, it is really a
good repository of information.
It says to use mkfdmn with -p and -x qualifiers in order to solve
a problem about heavy fragmented file systems, but it doesn't suggest values
to these parameters, do you know ? Do you want to see syscheck output file ?
Thanks again for your attention.

this is documented in the doc set...I don't remember where...
I would suggest *2 *4 of current value...
the real trick is to get them to run defragment regularly
