db2purescale异常卸载导致GPFS文件系统无法删除

###GPFS文件系统删除###

1. Unmount all GPFS file systems on all nodes by issuing the mmumount all -a command.

mmlsfs all

mmumount all -a

2. Issue the mmdelfs command for each file system in the cluster to remove GPFS file systems.

mmlsfs all

mmdelfs /dev/gpfs1nsd

3. Issue the mmdelnsd command for each NSD in the cluster to remove the NSD volume ID written on

sector 2.

If the NSD volume ID is not removed and the disk is again used with GPFS at a later time, you will

receive an error message when issuing the mmcrnsd command. See NSD creation fails with a message

referring to an existing NSD in the GPFS: Problem Determination Guide.
