Thanks to all who helped me with my problem.
Here is the original post:
------------------------------------8<----------------------------------
Hello,
Tomorrow morning, I'll have to temporarily copy some ADVFS file sets to
different disks in order to change something in the HSZ40 config of those
disks. I will take a backup first but a filesystem save/restore on disk
will be a lot faster when the time to restore will come.
I have the following procedure that I would like you to review, if you see
anything bad in it, please say so:
The only suspicion I got is the following:
I've noticed that whenever I create a fileset, under the directory onto
which it is mounted, there is a .tags directory as well as a quota.group
and some other file. Won't the vdump from A to /tempo destroy these files ?
Should I instead create a separate directory under /tempo (Ex.:
/tempo/savedset) and vdump the A fileset there instead of /tempo ? I also
worry about cleaning things up in /tempo before dumping another fileset in
it. What happens when the .tags and *.group files get destroyed ?
--------------------------------8<----------------------------------------
That scenario is OK. As for my doubts concerning the quotas and the .tags
directory, I should not worry. Someone mentionned that ADVFS does not dump
the quotas, you have to recreate them. The .tags directory is supposed to
be handled by the vdump command correctly (in fact, someone said it was
even "used" to create the dump)
Alan also mentionned to me that I could use the advfs utilities 'addvol'
and 'rmvol' to add the temporary device(s) that I plan to use, remove the
current device, do the maintenance, re-add the old devices and then remove
the temporary devices. It's a great idea, but I cannot evaluate how much
time this would take, and my filesystems are pretty full and fragmented. So
I'll stich to the good old vdump and restore (and defrag by the same time)
my filesets.
Thanks again !
