Information

OBS: Det går endast att logga in som root.

Rotfilsystem

Rotfilsystemet är ZFS och ligger på diskarna mfid[0-1]p2.

Lagringsyta för NFS

zpool storage med draid2. ligger på diskarna mfid[3-11]. Poolen är komprimerad med zstd.

NFS exporter

• forte.lysator.liu.se (130.236.254.143) | share grupp forte-nfs:3356
• ellen.lysator.liu.se (130.236.254.233) | share grupp runeberg-nfs:3357
• lisse.lysator.liu.se (130.236.254.175) | share grupp liss-nfs:3358

NFS server (FreeBSD)

/etc/rc.conf should contain:

nfs_server_enable="YES"
nfsv4_server_enable="YES"
mountd_enable="YES"

Dataset

zfs create storage/<datasetname> zfs set quota=<size> storage/<datasetname>

Quota

Forstor uses ZFS datasets. Use zfs set quota=2T storage/<datasetname> to set quota Get quota with zfs get quota storage/<datasetname>

NFS-exports

/etc/exports should contain:

V4: /storage #root of nfs export
/storage/<datasetname> -maproot="nobody":"nobody" I.P.ad.dr #squasing root and exporting to specific IP

NOTE: after making changes in /etc/exports restart mountd service mountd restart sometimes restart nfsd as well for good measure.

NFS client (Ubuntu)

Install package nfs-common

Test mounting the exported file system with sudo mount -t nfs4 -o proto=tcp,port=2049 192.168.0.177:/<datasetname> /mnt

Unmount with `umount.nfs4 /mnt/<datasetname>

If everything seems to work add the following to /etc/fstab:

192.168.0.177:/<datasetname> /mnt/<datasetname> nfs4 auto 0 0

to mount unmounted volumes from fstab do mount -a

Users and groups

All users who are to access this export need to exist both on server and client. With same IDs. They do not necessarily NEED to exist on the server, but it may be more convenient that way in case of ID conflicts later on on the servers side.

There needs to be a group set up that will be the owner of the shared directory on both sides. This also needs to have the same GID on both client and server.

I have tested on the servers side that the directory need only really have the group be correct. The directory can have root as owner and “forte” as group.
