On tsmsrvj I have in /etc/exports: /data/fex tsmsrvi(rw,async,no_subtree_check,no_root_squash) This is a btrfs subvolume with snapshots: root@tsmsrvj:~# btrfs subvolume list /data ID 257 gen 35 top level 5 path fex ID 270 gen 36 top level 257 path fex/spool ID 271 gen 21 top level 270 path fex/spool/.snapshot/2021-03-07_1453.test ID 272 gen 23 top level 270 path fex/spool/.snapshot/2021-03-07_1531.test ID 273 gen 25 top level 270 path fex/spool/.snapshot/2021-03-07_1532.test ID 274 gen 27 top level 270 path fex/spool/.snapshot/2021-03-07_1718.test root@tsmsrvj:~# find /data/fex | wc -l 489887
I can't remember if this is why, but I've had to put a distinct fsid field in each separate subvolume being exported: /srv/nfs/home -rw,async,fsid=0x1730,no_subtree_check,no_root_squash
I must export EACH subvolume?! The snapshots are generated automatically (via cron)! I cannot add them to /etc/exports -- Ullrich Horlacher Server und Virtualisierung Rechenzentrum TIK Universitaet Stuttgart E-Mail: horlacher@tik.uni-stuttgart.de Allmandring 30a Tel: ++49-711-68565868 70569 Stuttgart (Germany) WWW: http://www.tik.uni-stuttgart.de/ REF:[ref]
