GPFS (General Parallel File System) list, config, stop, start and status
The General Parallel File System (GPFS) is a high-performance shared-disk clustered file system
The default path of GPFS commands is: /usr/lpp/mmfs/bin GPFS status#mmgetstate -a
Node number Node name GPFS state
------------------------------------------
1 <node 1> active
2 <node 2> active
3 <node 3> active
4 <node 4> active
5 <node 5> active
6 <node 6> active
#mmgetstate -a -L
Node number Node name Quorum Nodes up Total nodes GPFS state Remarks
------------------------------------------------------------------------------------
1 <node 1> 1* 2 6 active quorum node
2 <node 2> 1* 2 6 active quorum node
3 <node 3> 1* 2 6 active
4 <node 4> 1* 2 6 active
5 <node 5> 1* 2 6 active
6 <node 6> 1* 2 6 active
After a start, the GPFS state can be “arbitrating” after a minute the status becomes “active” like above
#mmgetstate -a -L
Node number Node name Quorum Nodes up Total nodes GPFS state Remarks
------------------------------------------------------------------------------------
1 <node 1> 1* 0 6 arbitrating quorum node
2 <node 2> 1* 0 6 arbitrating quorum node
3 <node 3> 1* 0 6 arbitrating
4 <node 4> 1* 0 6 arbitrating
5 <node 5> 1* 0 6 arbitrating
6 <node 6> 1* 0 6 arbitrating
#mmstartup -a

#mmshutdown -a
