Chapter 3. Running and Managing DX Storage CFS

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.

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.
