[Lustre-discuss] Correct way to unmount a lustre client?

Tue Jul 8 09:30:19 PDT 2008

Hello,

what is the correct way to unmount a lustre client
when a simple "umount <filesystem>" responds with
"device is busy"? A "umount -l <filesystem>" does
unmount the filesystem however when I reboot the
machine subsequently the shutdown process hangs.
The last messages on console are:

LustreError: 131-3: Received notification of device removal
Please shutdown LNET to allow this to proceed

Best regards,
Hans Schnitzer
