Chapter 5. Managing GFS 35
Option Description
oopses_ok
This option allows a GFS node to not panic
when an oops occurs. (By default, a GFS node
panics when an oops occurs, causing the file
system used by that node to stall for other GFS
nodes.) A GFS node not panicking when an
oops occurs minimizes the failure on other
GFS nodes using the file system that the failed
node is using. There may be circumstances
where you do not want to use this option —
for example, when you need more detailed
troubleshooting information. Use this option
with care.
Note: This option is turned on automatically if
lock_nolock
locking is specified; however,
you can override it by using the
ignore_local_fs
option.
upgrade
Upgrade the on-disk format of the file system so
that it can be used by newer versions of GFS.

The GFS file system can be unmounted the same way as any Linux file system — by using
the
umount
command.
Note
The
umount
command is a Linux system command. Information about this command can
be found in the Linux
umount
command man pages.
