gpfs 修改 failure group
1、查看nsd 的failure group
[root@g0 ~]# mmlsdisk gpfs disk driver sector failure holds holds storage name type size group metadata data status availability pool ------------ -------- ------ ----------- -------- ----- ------------- ------------ ------------ metansd00 nsd 512 100 Yes No ready up system metansd01 nsd 512 101 Yes No ready up system metansd02 nsd 512 102 Yes No ready up system datansd00 nsd 512 103 No Yes ready up datapool datansd01 nsd 512 104 No Yes ready up datapool datansd02 nsd 512 105 No Yes ready up datapool
2、修改datansd02 的failure group 为106
编辑nsdfile.cfg
#%pool: pool=system blockSize=512K layoutMap=cluster #%pool: pool=datapool blockSize=2M layoutMap=cluster writeAffinityDepth=1 blockGroupFactor=256 #%nsd: device=/dev/vdb servers=g0 nsd=metansd00 usage=metadataOnly pool=system #%nsd: device=/dev/vdb servers=g0 nsd=metansd00 usage=metadataOnly failureGroup=100 pool=system #%nsd: device=/dev/vdb servers=g1 nsd=metansd01 usage=metadataOnly failureGroup=101 pool=system #%nsd: device=/dev/vdb servers=g2 nsd=metansd02 usage=metadataOnly failureGroup=102 pool=system #%nsd: device=/dev/vdb servers=g1 nsd=metansd01 usage=metadataOnly pool=system #%nsd: device=/dev/vdb servers=g2 nsd=metansd02 usage=metadataOnly pool=system #%nsd: device=/dev/vdb servers=g3 nsd=datansd00 usage=dataOnly failureGroup=103 pool=datapool #%nsd: device=/dev/vdb servers=g4 nsd=datansd01 usage=dataOnly failureGroup=104 pool=datapool #%nsd: device=/dev/vdb servers=g5 nsd=datansd02 usage=dataOnly failureGroup=105 pool=datapool %nsd: device=/dev/vdb servers=g5 nsd=datansd02 usage=dataOnly failureGroup=106 pool=datapool
修改nsd
mmchdisk gpfs change -F nsdfile.cfg
查看修改后的nsd
[root@g0 gpfs_config]# mmlsdisk gpfs disk driver sector failure holds holds storage name type size group metadata data status availability pool ------------ -------- ------ ----------- -------- ----- ------------- ------------ ------------ metansd00 nsd 512 100 Yes No ready up system metansd01 nsd 512 101 Yes No ready up system metansd02 nsd 512 102 Yes No ready up system datansd00 nsd 512 103 No Yes ready up datapool datansd01 nsd 512 104 No Yes ready up datapool datansd02 nsd 512 106 No Yes ready up datapool Attention: Due to an earlier configuration change the file system is no longer properly replicated.
重新平衡副本
