The customer can use the new space by creating new vdisk sets from the available space. When the
vdisk sets are added to the existing file system (if required), the restripe operation can be run. For
more information, see IBM Spectrum Scale: Administration Guide.
Example: Manually restarting GPFS on the ESS 3000 canisters
You can manually stop and start GPFS to solidify the nodes configuration changes on both canisters.
For configuration changes to take effect, restart GPFS on one canister at a time, and ensure that at least
one of the canisters is always in the active state. It is also important to understand the effect of losing
quorum on the canister during the GPFS recycling.
1. Check the quorum state by issuing the following command:
# mmgetstate -s
A sample output is as follows:
Node number
-------------------------------------------
21
Summary information
---------------------
Number of nodes defined in the cluster:
Number of local nodes active in the cluster:
Number of remote nodes joined in this cluster:
Number of quorum nodes defined in the cluster:
Number of quorum nodes active in the cluster:
Quorum = 4, Quorum achieved
2. Shut down GPFS on a canister by issuing the following command:
# mmshutdown -N canisterA
3. Start GPFS on a canister by issuing the following command:
# mmstartup -N canisterA
4. Check the state of GPFS on both canisters by issuing the following command:
# mmgetstate -N this ESS 3000 node class
A sample output is as follows:
