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?
Maybe in single user mode, but /var is needed for multi-user mode to function.
Remember: if shrinking, shrink filesystem first then LV, if expanding then expand the LV first then the filesystem.
