If a GFS Shared File System is used, mount it on all the nodes. In such a case, execute the "sfcmntgl(8)" command on any one of the nodes where the GFS Shared File System will be used.
If it is only used on one node, mount the file system using sfcmount(8). If this command is executed, sfcfsd and MDS will be started on a MDS node is configured. Then, the file system will be mounted on all the nodes.
Note
If the file system is not added in /etc/fstab, mounting of the file system will fail. Also, sfcmntgl(8) and sfcmount(8) are not used for the mount option. If either of them is executed, the current mount option that is specified for the mount option filed of /etc/fstab will be used.
If the file system is mounted on all the nodes, execute sfcmntgl(8) on any one of the nodes.
See
For details on sfcmntgl(8), see sfcmntgl(8).
You can mount the file system on all the nodes as follows:
When the mount point is specified:
# sfcmntgl /mnt/fs1 <Enter> Mount point: /mnt/fs1 |
When a representative partition is specified:
# sfcmntgl /dev/sfdsk/gfs01/dsk/volume01 <Enter> Representative partition: /dev/sfdsk/gfs01/dsk/volume01 |
When both the mount point and a representative partition are specified:
# sfcmntgl /dev/sfdsk/gfs01/dsk/volume01 /mnt/fs1 <Enter> Representative partition: /dev/sfdsk/gfs01/dsk/volume01 Mount point: /mnt/fs1 |
If mounting fails for a node, the name of the node on which the failure occurred is reported.
If you want to mount a file system on specific nodes, use sfcmount(8). Then, the file system will only be mounted on the nodes where the file system will be shared.
Note
After the GFS Shared File System is mounted on one or more MDS nodes, it should be mounted on a node which is not the MDS node. Or, the GFS Shared File System should be mounted at the same time on all nodes by using sfcmntgl(8). The GFS Shared File System cannot be mounted first on a node which is not the MDS node.
See
For details on sfcmount(8), see sfcmount (8).
For details on sfcmntgl(8), see sfcmntgl (8).
Mount the GFS Shared File System on the node as shown below:
When the mount point is specified:
# sfcmount /mnt/fs1 <Enter> Mount point: /mnt/fs1 |
When a representative partition is specified:
# sfcmount /dev/sfdsk/gfs01/dsk/volume01 <Enter> Representative partition: /dev/sfdsk/gfs01/dsk/volume01 |
When both the mount point and a representative partition are specified:
# sfcmount /dev/sfdsk/gfs01/dsk/volume01 /mnt/fs1 <Enter> Representative partition: /dev/sfdsk/gfs01/dsk/volume01 Mount point: /mnt/fs1 |
