Hmm, following this discussion I decided tor experiment a little bit with btrsf and converted some data-/home-partitions from ext3/ext4 into btrsf.
Went fine so far, the only issue I currently have is that I wanted to mount those partitions via "LABEL=" in fstab.
That fails on one box but seems to work on another box :?
The fstab-entry which doesn't work is as follows:LABEL=Server /srv btrfs defaults,noatime,subvol=__active 0 0
where the working line on the other box is: LABEL=USB320GB /media/USB320GB btrfs auto,users,rw,noatime 0 [0
A mount -a brings :
mount: Datei oder Verzeichnis nicht gefunden
LABEL=Server /srv btrfs defaults,compress,noatime,subvol=__active 0 0
(File or directory not found)
I helped myself by testing the necessary mount-command manually and inserting it then into rc.local
mount -t btrfs LABEL=Server /srv
Any idea on that behavior ?
Also I have currently on one box an logical volume formatted with ext4 which includes partitions on two disks. I would like to convert that to btrfs too.
Is it reasonable to just convert the ext4-File-System into btrfs and leave the underlying volume group untouched ?
As I understand btrfs itself has the same feature by adding several Partitions on different disk to one logical partition and doesn't need LVM. So what is the best way for that?
Leaving LVM alone and just converting the file-system or should I and create that btrsf-Volume from scratch and reload the backup (a whole lot of dvds)?
Has somebody some suggestions or hints on that :?
regards
Reiner
Edit: I solved the fstab-issue for now with this entry:
LABEL=Server /srv btrfs defaults,compress,noatime,subvol=__active 0 0
This seems to work as I had planned it
