RHBA-2009:0132 - Bug Fix Advisory

Topic

Updated gfs-kmod packages which fix several issues are now available.

Description

The gfs-kmod packages contain kernel modules that provide the functionality
to mount and use GFS file systems.

These updated packages apply the following bug fixes:

• A bug was fixed which caused a 'gfs_glock_is_locked_by_me(ip->i_gl)'

error in the system log.

• gfs mount attempts no longer hang if no more journals are available.
• GFS filesystems on devices that are not in '/dev/' can now be mounted

properly.

• An assertion (!(lck_ret & LM_OUT_ERROR)) triggered by gfs_grow has been

fixed.

• The noatime and nodiratime options mount options are now properly honored

by the gfs kernel module.

• It was possible for the inode glock holder to never be dequeued through

gfs_readpage which would cause an assertion.

• A bug which caused corruption when a node was forced to withdraw has been

fixed.

• A bug which caused a fault in posix_lock_file() was fixed by implementing

the F_CANCELLK command in gfs_lock().

• A bug which caused gfs to appear to hang due to wasteful prefetching of

locks has been fixed.

Users are advised to upgrade to these latest gfs-kmod packages, which are
updated for use with Red Hat Enterprise Linux 5.
