6.2 HP IBRIX 9000 Storage CLI Reference Guide (TA768-96070, December 2012)

ibrix_umount

Unmounts a file system.

Description

ibrix_umount unmounts a file system from file serving nodes, IBRIX 9000 clients, and host

groups. You can also locally unmount a file system from Linux 9000 clients with ibrix_lwumount.

File serving nodes immediately unmount a file system. For IBRIX 9000 clients the intention to unmount

a file system is stored on the Fusion Manager. When IBRIX software services start on a 9000 client,

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

them. If IBRIX software services are already running on a 9000 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.
