Smile Moving /var to another LVM: Keep quotas?

Hi there,

I have four LVMs on top of a RAID 1, like this:

Dateisystem          1K‐Blcke   Benutzt Verfgbar Ben% Eingehngt auf
/dev/mapper/vg0-root  31209468  20995024   8641580  71% /
tmpfs                  4095408         0   4095408   0% /lib/init/rw
udev                   4089952       176   4089776   1% /dev
tmpfs                  4095408         0   4095408   0% /dev/shm
/dev/md0                254699     20116    221431   9% /boot
/dev/mapper/vg0-lv1  104031520    192248  98596392   1% /lv1
/dev/mapper/vg0-lv2  104031520    192248  98596392   1% /lv2
/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

Any hints?

Added question: Will the links be preserved when I move stuff? Options for moving? rsync -a ?
