Re: [Networker] Cleaning out /nsr/tmp ???
2010-07-31 10:40:24
I was considering (and might do this in the future) moving /nsr/tmp
as well as /nsr/res/jobsdb to /tmp. This should, in theory (with Solaris
swap mounted tmp), improve the performance of these directories and
remove altogether the need to clear them. The only problem I can see
with this is that NDMP backups can consume a lot of disk space in
/nsr/tmp (I have seen as much as 5Gb of disk usage) so your memory and
swap should be large enough for that. Also keep in mind that this
approach will put more pressure on your memory and will compete with
other memory intensive processes (ZFS is also a memory hog). So, if you
try this monitor your performance and /tmp available disk space
carefully (also in the middle of the night when your NDMP backups are
running).

A few questions here on /nsr/tmp.
It's currently only 4.6 MB, and it's not being backed up as there is a
default /nsr/tmp/.nsr file to skip everything under there, so I'm
assuming that EMC doesn't consider this information vital.
1. *If* you shut down NW first, is it safe to remove everything under
/nsr/tmp ?
2. When you re-start NW, will it automatically re-create the 'tmp'
directory, or will it be necessary to first manually re-create it before
restarting NW?
3. I see a number of older lock files under /nsr/tmp and lots of client
completion information files named like:
/nsr/tmp/sg/groupname/ss.client.blah-blah-blah.
It looks like these get replaced each day, but regardless, do I really
need any of the stuff under /nsr/tmp?
Will removing everything under tmp cause any headaches to NW, e.g. give
it heart failure or cause it to fail to operate properly, wherein maybe
somehow it might expect to see previous information stored under there
somewhere, but now it can no longer access it?
4. Is it recommended to periodically clean out tmp?
Thanks.
