# exdsmgr mount device=psv5
where psv5 is the filesystem label.
This mounts the filesystem on all servers using the existing mount options that were used when the
filesystem was created. The mount command queries the system to determine what mount options
were previously used for the filesystem in question and then reuses those options without modification.
Use the exdsmgr unmount command to unmount a filesystem on all servers, as shown in the following
example:
# exdsmgr unmount device=psv5
where psv5 is the filesystem label.
NOTE:
You can also use the mxconsole or mx(8) commands to mount, unmount, and perform other
operations on a filesystem.
NOTE:
Any time the mx fs mount, exdsmgr create filesystem, or exdsmgr mount command
is run, the logtotty option appears in the list of mount options. This option allows mount errors to
be logged to a tty. Unlike the other mount options, the logtotty option is not preserved after a
reboot.
Changing mount persistence
To remove persistence from all servers for a specific filesystem without unmounting the filesystem, use
the following command:
# mx fs unmount --persistent psv5 ALL_SERVERS
where psv5 is the filesystem label.
To unmount filesystem psv5 from all servers without removing persistence, use the following command:
# mx fs unmount --active psv5 ALL_SERVERS
where psv5 is the filesystem label.
Modifying a filesystem
The exdsmgr modify filesystem device=label command (where label is the filesystem
label) allows you to modify the following attributes of a filesystem:
• PSFS quotas—Can be enabled or disabled by using the command as follows: enabled or dis-
abled.
• Enable quotas—
# exdsmgr modify filesystem device=psv5 psfs_options=--quotas
• Disable quotas—
# exdsmgr modify filesystem device=psv5 psfs_options=--noquotas
