I've done it before on a quiet system and it worked fine. Still think its a bit risky if you cant get to it for 2 days. > I already moved /var/logs to it's own LVM partition but it didn't help > at all so I think it's better to rather just resize it.

If you "urgently need to install new software", then a small possibility of breaking the system for 2 days is probably a show stopper. I'd continue with your approach (as a temporary solution) of migrating bits of /var to a different LVM. If moving /var/logs didn't help, you need to track down the big directories. Try du -sh /var/* then drill down though your big candidates /var/cache/yum, /var/spool, and /var/tmp are always candidates for clean up. Hope this helps. Kal
