6.1 HP IBRIX X9000 Network Storage System CLI Reference (TA768-96057, June 2012)

ibrix_umount

Unmounts a file system.

Description

ibrix_umount unmounts a file system from file serving nodes, X9000 clients, and hostgroups.

You can also locally unmount a file system from Linux X9000 clients with ibrix_lwumount.

File serving nodes immediately unmount a file system. For X9000 clients the intention to unmount

a file system is stored on the Fusion Manager. When X9000 software services start on a X9000

client, the client queries the Fusion Manager for the file systems to be unmounted and then unmounts

them. If X9000 software services are already running on a X9000 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.
