I have four LVMs on top of a RAID 1, like this:
Dateisystem 1K‐Blöcke Benutzt Verfügbar Ben% Eingehängt auf

/dev/mapper/vg0-lv3 486220392 8893844 452822436 2% /lv3
As / is getting filled up and I need more space in the future, I'd like to move /var to /lv1.
I thought I'll boot into my rescue system, mount / and /lv1, them move the contents of folder /var into /lv1 (currently empty) - and then I'd need the right /ec/fstab changes in order to make the quota functioning again.
I'm not sure about the mount options - plus it's a production server...
All the lv's are on top of a RAID1 /dev/md1
Added question: Will the links be preserved when I move stuff? Options for moving? rsync -a ?
