6.5 HP StoreAll OS CLI Reference Guide

ibrix_umount
Unmounts a file system.
Description
ibrix_umount unmounts a file system from file serving nodes, StoreAll clients, and host groups.
You can also locally unmount a file system from StoreAll Linux clients with ibrix_lwumount.
File serving nodes immediately unmount a file system. For StoreAll clients the intention to unmount
a file system is stored on the Fusion Manager. When StoreAll software services start on a StoreAll
client, the client queries the Fusion Manager for the file systems to be unmounted and then unmounts
them. If StoreAll software services are already running on a StoreAll client, you can force the client
to query the Fusion Manager by either executing ibrix_lwmount -a on the client or by rebooting
it.
The root segment must be the last segment unmounted. Attempting to unmount it while other segments
are still mounted will fail.
If the file system has been exported using NFS, you must unexport it with ibrix_exportfs before
you unmount it.
