Chapter 3. Running and Managing DX Storage CFS

3.1. Starting DX Storage CFS and CNS

The Cluster Name Space should always be started prior to CFS. The name space can be started
using the following command:
$ /etc/init.d/caringo-cns start
CNS will fail to start and print an appropriate error message if one of several critical configuration
parameters is missing or invalid. Once the configuration is corrected via the cns-admin script, CNS
should start correctly.
DX Storage CFS will start automatically when the DX Storage CFS server boots if the "mount on
boot" option was selected during the configuration process for each mountpoint. If the process was
stopped for any reason it can be manually started with a standard mount command. To mount all
configured DX Storage CFS mountpoints at once, type in the following command:
$ sudo /etc/init.d/caringo-cfs start
To mount a single mountpoint that was previously defined using the cfs-admin mkfs script, run a
command similar to the following (where /mnt/testMount1 is the mounted destination for the desired
mountpoint)
$ sudo mount /mnt/testMount1
CFS will fail to mount a share and will print an appropriate error message if one of several critical
configuration parameters is missing or invalid. Once the configuration is corrected via the cfs-admin
mkfs script, the share should mount correctly.
Before writing any data to a mountpoint, run a 'mount' command with no options to ensure the
desired mountpoints started correctly and are present in the mounted list. If the mountpoint is not in
the mounted list, the install was not successful and you should not write any data to the mountpoint.

3.2. DX Storage CFS and CNS Shutdown

To stop DX Storage CFS and unmount all configured shares, use the following command:
$ sudo /etc/init.d/caringo-cfs stop
To stop and/or unmount a specific configured share, use a command similar to the following
(where /mnt/testMount1 is the mounted destination for the mountpoint):
$ sudo umount /mnt/testMount1
For file systems shared via Samba, NFS, etc, administrators may need to stop associated file
system services before they can cleanly unmount CFS.
Note
If DX Storage CFS is stopped using a kill command, a 'fusermount -u /mnt/mountpoint'
command must be executed before restarting to ensure the mountpoint is properly
released and remounted. If the remount option is utilized, the mountpoint will be
unmounted and then immediately mounted.
