Modifying file system attributes 5–33
3. When the file system has stopped, enter the
modify filesystem filesystem_name
command,
as shown in the following example:
sfs> modify filesystem data
Select an option:
1) Add OSTs
2) Change stripe size
3) Change stripe count
4) Change mount point
5) Change preferred servers
6) Change LUN mount options
7) Change interconnect
8) Change Lustre timeout
9) Change quota options
w) Rewrite LDAP configuration data
c) Cancel
Enter your choice [c]:
4. Select the
LUN Mount Options
menu item, as follows.
Enter your choice [c]: 6
You are first prompted to enter the MDS mount options, and then prompted to enter the OST options
If you are specifying more than one mount option for one of the service types (OST or MDS), type in
the options in a comma-separated list, with no spaces or semicolons in the list. You can clear the list
of options by typing in two double quotes (
""
).
5. To bring the changes into effect, restart the file system, as shown in the following example:
sfs> start filesystem data
Once specified, the mount options are used each time the file system is started.
6. When the file system restarts, the client nodes can remount the file system. If a client node fails to
remount the file system, reboot the client node.
5.6.4 Modifying file system interconnects
You can use the
show networks
command to display the list of interconnects, as shown in the following
example:
sfs> show networks
Name Device Role
---- ------ ----
gm0 n/a interconnect
mp0 n/a console
nic1 eth0 management
nic2 eth1 interconnect
Note that the first interconnect that is listed in the
Interconnect
field in the output from the
show
filesystem filesystem_name
command is the interconnect that is used by the MDS service for
communication with the OST services in the file system. This interconnect must be functioning correctly
between the administration and MDS servers and the Object Storage Servers; if it is not, the MDS service
cannot function correctly. In the following example, the Gigabit Ethernet interconnect is used by the MDS
service:
sfs> show filesystem data
Name: data
OSTs: ost[10-15]
State: started
Mountpoint: /usr/data/
Stripe Size: 4194304
Stripe Count: 6
Interconnect: tcp elan
