To change the GFS Shared File System, unmount it on all the nodes.
First, stop using the file system by stopping applications.
Then, unmount the file system.
Check if the file system is unmounted properly on all the nodes using sfcrscinfo(8).
See
In order to use the process of the file system, execute fuser(1). For details about the command, see the online manual page.
For information on how to check the file system status using sfcrscinfo(8), see "11.2.5 Checking file system status."
To unmount the file system on all the nodes, use sfcumntgl(8). Execute the command on any one of the nodes where the file system is shared.
See
For details on sfcumntgl(8), see sfcumntgl(8).
When the mount point is specified:
# sfcumntgl /mnt/fs1 <Enter> Mount point: /mnt/fs1 |
When a representative partition is specified:
# sfcumntgl /dev/sfdsk/gfs01/dsk/volume01 <Enter> Representative partition: /dev/sfdsk/gfs01/dsk/volume01 |
If unmounting fails on a node, the name of the node on which the failure occurred is reported.
To unmount the file system on specific nodes, use sfcumount(8). Execute the command on any one of the nodes where the file system is shared.
Note
In the GFS Shared File System without running the secondary MDS, when you unmount the file system on the primary MDS node, please finish the unmount on all other nodes or use sfcumntgl(8). Otherwise the state of GFS Shared File System on the other nodes becomes blockade.
See
For details on sfcumount(8), see sfcumount(8).
For details on sfcumntgl(8), see sfcumntgl(8).
Unmount the GFS Shared File System on the node as shown below:
When the mount point is specified:
# sfcumount /mnt/fs1 <Enter> Mount point: /mnt/fs1 |
When a representative partition is specified:
# sfcumount /dev/sfdsk/gfs01/dsk/volume01 <Enter> Representative partition: /dev/sfdsk/gfs01/dsk/volume01 |
Note
To unmount the GFS Shared File System, be sure to use sfcumount(8).
