/nfs/localhost/fex is just a test setup on a test server.
The production server does not use nfs so far, but we plan to migrate from
local disks to nfs. But before we do it, btrfs via nfs MUST work without
problems and error messages.
/nfs/localhost/fex is not in /etc/fstab, I have mounted it manually, as I
wrote in my previous mails. It is just a test.
root@tsmsrvj:# grep local /etc/exports
/data/fex localhost(rw,async,no_subtree_check,no_root_squash,fsid=20000001)
root@tsmsrvj:# mount -v localhost:/data/fex /nfs/localhost/fex

root@tsmsrvj:# snaprotate -v test 5 /data/fex/spool

We cannot move the snapshots to a different directory. Our workflow
depends on snaprotate:
