In a site, the N8000 restarts a service node while there has the NFS service, there is a file system is offline, and then causes this file system is not accessible.
1. Login the cluster’s management interface’s “storage” mode, use the “fs fsck fsname” command to implement the file system repair, after completing the repair, we need to use the command “fs online fsname” to make the file system is online.
2. If the “fs fsck” command can’t be executed, we must use the “support” account to login the cluster node. Firstly, use the “cfsmntadm display” command to check if the file system is still in mount, if it’s still in mount, use the “cfsumount” command to uninstall the file system.
3. In the “support” account, execute “fsck –t vxfs –o full –y /dev/vx/dsk/sfsdg/fsname” command to view the file system fully.
4. Use the “fs online fsname” command to make the file system is online
The time of the restarted node is not consistent with the master node’s time, in order to protect the file system’s consistency, the cluster configures the file system’s flag bit as “1” forcibly, and then causes the file system is offline.
