Re: [Veritas-bu] strange disk usage

Yes, I think this is it...
Operations does a lot of restores, and I'll have to check
whether this corresponds to the drops and recovery of disk
space.
In the meantime, I'll have to go through the pain of copying
the veritas filesystem to a larger partition...
We were going to have to do this soon
anyway...
I love my job! Thanks
:)
That's the only thing I can think of,
too (other than logs, but that would be more of a gradual increase than all at
once, I would think).
Keep in mind
that catalog compression will keep the catalog compressed until someone needs to
search that data, such as for a restore or bplist. The image will then be
expanded. If you have someone doing restores that could be contributing to the
problem, especially if the image is huge. It would also account for the apparent
randomness of it.

You're a good shot when it's dark! yes, I see the Compress Catalog Interval checked and set for 2
days. This doesn't happen every
two days, though; makes me wonder if it may happen after some many backups, or a
set amount backed up... Thanks

Just a shot in the dark, but have you enabled image compression? We
have servers with millions of tiny files that produce huge images files (5GB+)
and compressing those into a .tgz might chew up a fair amount of space before
the original image gets deleted. -Jonathan From:

veritas-bu AT mailman.eng.auburn DOT edu Subject: [Veritas-bu] strange disk
usage Hey all - Just wondering if
anyone has run into this. We've set up our
/usr/openv (/veritas) filesystem on a separate filesystem about 300GB in
size. Right now, we're down to about 60Gb
free, and I've been receiving low diskspace alerts. It seems that there is something chewing up about 20-30GB of space in
this filesystem on a sporadic schedule. Looks
like it generally happens 2-3 times a week, and I've discovered that it's been
happening for a while after some research. Normally it's not an issue, but since we're getting down to low
available free space, it's become an issue. I'm wondering if anyone has come across a netbackup process that
would do this? When it was occuring
yesterday, I searched for large files, and found none, so it must be a lot of
small files accumulating. We're running NB
6.5.6. Thanks in advance for any input! Dan K
