Hi.
I want to make a snapshot from a logical volume and noticed that there must be enough free disk space in the volume group. Actually there is no free disk space left. How do i shrink online /var without losing any data or restore from backup?
You can't shrink ext2/ext3 filesystems online. You'll have to schedule a downtime. Another solution is to remove and use a file for swap (swapoff ... && lvremove ...), or reduce it (swapoff ... && lvreduce ... && mkswap && swapon).
Hi.
Is it possible that i log into the server with ssh and umount only /var and then resize the logical volume?
Yes, but you'll have to stop a lot of daemons and other processes that run with files opened in /var.
You can find the processes accessing /var with lsof or fuser: # fuser -mv /var # lsof /var
