mmvdisk: Checking resources for specified nodes.
mmvdisk: Node class 'ess3200_x86_64_mmvdisk_78E400K' has a shared recovery group disk
topology.
mmvdisk: Using 'ess3200.shared' RG configuration for topology 'ESS 3200 FN1 24 NVMe'.
mmvdisk: Updating configuration for node class 'ess3200_x86_64_mmvdisk_78E400K' (recovery
group 'ess3200_78E400K').
mmvdisk: Recording post-conversion cluster configuration in /var/mmfs/tmp/
mmvdisk.configure.after.20210816
mmvdisk: Restarting GPFS daemon on node 'ess3200rw3a-hs.gpfs.ess'.
mmvdisk: Restarting GPFS daemon on node 'ess3200rw3b-hs.gpfs.ess'.
Important: This command automatically stops and restarts GPFS on each canister server in a serial
fashion by using the --recycle 1 option. If you do not want to stop and restart GPFS, the server
can be configured without the --recycle 1 option. The customer can restart GPFS manually on
each canister server by the process at each step. For more information about manually restarting
GPFS, see "Manually restarting GPFS on the Enterprise Storage Server 3200 canisters example" on
page 29.
