Unmounting a file system through GUI
You can use the IBM Storage Scale GUI to mount or unmount individual file systems or multiple file systems on the selected nodes. Use the , , or page in the GUI to mount or unmount a file system.
You can utilize the following options that are supported in the GUI to unmount
file systems:
- Unmount local file system from local nodes and remote nodes.
- Unmount a remote file system from the local nodes. When a local file system is unmounted from the remote nodes, the remote nodes can no longer be seen in the GUI. The page lists the remote nodes that currently mount the selected file system. The selected file system can be a local or a remote file system but the GUI permits to unmount only local file systems from the remote nodes.
- Select individual nodes, protocol nodes, or nodes by node class while selecting nodes from which the file system needs to be unmounted.
- Specify whether to force unmount. Selecting the Force unmount option while unmounting the file system unmounts the file system even if it is still busy in performing the I/O operations. Forcing the unmount operation affects the outstanding operations and causes data integrity issues. The IBM Storage Scale system relies on the native unmount command to carry out the unmount operation. The semantics of forced unmount are platform-specific. On certain platforms such as Linux®, even when forced unmount is requested, file system cannot be unmounted if it is still referenced by system kernel. To unmount a file system in such cases, identify and stop the processes that are referencing the file system. You can use system utilities like lsof and fuser for this.
