Question about PFS default partition choice on mount

Hi guys,
I have a question on how to manage partitions with the DragonFly and
Hammer2.
My goal is to replicate a ZFS I had with FreeBSD so I would like to
create individual PFSes for all my NFS exports so I can manage storage,
snapshots, backups etc at that level.
I installed 5.4.2 and choose to leave everything in the partition the
same with the exception of making / 100GB and /build 100GB and
dedicating the rest of my large disk to /exp so I ended up with:
df -h:
Filesystem Size Used Avail Capacity Mounted on
serno/ZAD2RVKD.s1d 99.3G 637M 98.7G 1% /
devfs 1024B 1024B 0B 100% /dev
/dev/serno/ZAD2RVKD.s1a 1022M 186M 754M 20% /boot
/dev/serno/ZAD2RVKD.s1e at DATA 99.3G 3072K 99.3G 0% /build
/dev/serno/ZAD2RVKD.s1f at DATA 5303G 64.0K 5303G 0% /exp
/build/usr.obj 99.3G 3072K 99.3G 0% /usr/obj
/build/var.crash 99.3G 3072K 99.3G 0% /var/crash
/build/var.cache 99.3G 3072K 99.3G 0% /var/cache
/build/var.spool 99.3G 3072K 99.3G 0% /var/spool
/build/var.log 99.3G 3072K 99.3G 0% /var/log
/build/var.tmp 99.3G 3072K 99.3G 0% /var/tmp
tmpfs 1926M 0B 1926M 0% /tmp
procfs 4096B 4096B 0B 100% /proc
I created myself a PFS like so:
h2 pfs-create exp-backup
hammer2 pfs-list
Type ClusterId (pfs_clid) Label
MASTER 0cbef96e-685a-11e9-8a8c-55bf647a66bb exp-backup
MASTER 5ce0575e-6839-11e9-86d4-55bf647a66bb ROOT
MASTER 5ce056a8-6839-11e9-86d4-55bf647a66bb LOCAL
... and then tried to mount it into my large partition allocation which
fails with 'Invalid arguement' because the PFS label is not found
mount_hammer2 /dev/serno/ZAD2RVKD.s1f at DATA@exp-backup /exp/backup/
mount: : Invalid argument
ls /dev/serno/
ZAD2RVKD ZAD2RVKD.s1 ZAD2RVKD.s1a
ZAD2RVKD.s1b ZAD2RVKD.s1d ZAD2RVKD.s1e ZAD2RVKD.s1f
I am about to reinstall and put my /exp partition right after root
and /build last and see if then I can mount in the larger partition as
I want, but was wondering if there is something else I can do to end-up
with a PFS being mounted on the right partition.
Thanks in advance!
George
