MxFS-Linux Configuration
The MxFS-Linux configuration is stored in an online database. To back up
the information in the database, you will need to save the Export Group
configuration and the NLM state.
Save the Export Group Configuration
Run the following command to save the configuration information for
your Export Groups:
$ mx exportgroup dump
In addition to reporting the export group configuration, this command
creates a file in the current directory for each export group. The files
contain the export records for the export groups and are named
dump_<exportgroupname>_<time_in_milliseconds>. You will need to save
these files.
To restore the files, run the following command:
$ mx --continue --file dump_<exportgroupname>_<time_in_milliseconds>
Save the NLM State
You should also save the state of the Network Lock Manager (NLM),
which will be either enabled or disabled. Run the following command to
determine the state:
/opt/polyserve/bin/mxnlmconfig -q
This command returns a sentence stating whether NLM locking is
enabled or disabled. Be sure to save this information.
On restore, run mxnlmconfig again, using the -e option to enable NLM
locking, or the -d option to disable NLM locking.
Membership Partitions
Use the Matrix Server mpdump command to save the membership
partition data. The following command saves the data to the default
backup file (/var/opt/polyserve/run/MP.backup).
# /opt/polyserve/lib/mpdump -F
Be sure to back up /var/opt/polyserve after running mpdump.
