|
|
|
|
Mount and manage NFS shares from remote servers (nfs-common).
|
|
|
|
Commands:
|
|
mount <server:export> <local-dir> One-shot mount (creates local-dir if needed)
|
|
unmount <local-dir> Unmount the share
|
|
list Show active NFS mounts
|
|
persist <server:export> <local-dir> Persistent mount via a systemd .mount unit
|
|
(ordered after network-online.target)
|
|
unpersist <local-dir> Stop, disable and remove the mount unit
|
|
|
|
Examples:
|
|
pos system nfs-client mount 100.100.100.1:/srv/media /mnt/nfs/media
|
|
pos system nfs-client persist 100.100.100.1:/srv/media /mnt/nfs/media
|
|
pos system nfs-client list
