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?
