gfs_grow - Expand a GFS filesystem
SYNOPSIS
gfs_grow [OPTION]... <DEVICE|MOINTPOINT>...
DESCRIPTION
gfs_grow is used to expand a GFS filesystem after the device upon which the filesystem resides has also been expanded. By running gfs_grow
on a GFS filesystem, you are requesting that any spare space between the current end of the filesystem and the end of the device is filled
with a newly initialized GFS filesystem extension. When this operation is complete, the resource index for the filesystem is updated so
that all nodes in the cluster can use the extra storage space which has been added.
You may only run gfs_grow on a mounted filesystem; expansion of unmounted filesystems is not supported. You only need to run gfs_grow on
one node in the cluster. All the other nodes will see the expansion has occurred and automatically start to use the newly available space.
You must be superuser to execute gfs_grow. The gfs_grow tool tries to prevent you from corrupting your filesystem by checking as many of
the likely problems as it can. When expanding a filesystem, only the last step of updating the resource index affects the currently
mounted filesystem and so failure part way through the expansion process should leave your filesystem in its original unexpanded state.
You can run gfs_grow with the -Tv flags to get a display of the current state of a mounted GFS filesystem. This can be useful to do after
the expansion process to see if the changes have been successful.
gfs_grow will consume all the remaining space in a device and add it to the filesystem. If you want to add journals too, you need to add
the journals first using gfs_jadd.
OPTIONS -h Prints out a short usage message and exits.
-q Quiet. Turns down the verbosity level.
-T Test. Do all calculations, but do not write any data to the disk and do not expand the filesystem. This is used to discover what the
tool would have done were it run without this flag. You probably want to turn the verbosity level up in order to gain most informa-
tion from this option.
-V Version. Print out version information, then exit.
-v Verbose. Turn up verbosity of messages.

I have a CentOS release 5.2 (Final)host running kernel 2.6.18-92.el5 with at raid 10 that had two mirrored drives fail. The drives were re-inserted and now the raid shows healthy (for now). I tried to mount but got an Input/output error. I then attempted a fsck:

Looking for suggestions as to which filesystem to go with. I currently use gfs2 on hosts with 3.4tb useable. I understand gfs2 is being left behind but xfs and ext4 are not quite certified completely on CentOS 5.2. I have email storage hosts that have a decent i/o requirement and 12TB usable after...

Hi,
I have a bit knowledge of GFS. As per my understanding it is the file system used in the cluster environment.
I have a question. Is GFS 6.2 same as GFS 2 files system?
Please some one clear my confusion.
Thanks in advance. (1 Reply)
Hey everyone. I am in the process of setting up an iSCSI SAN to function as a log storage device for a number of servers. All of the initiators see the volume, and originally I formatted it with ext3 and went on my merry way. However after some research I'm having concerns that I should nuke the... (1 Reply)

Hi all,
I'm a bit new to advanced filesystem types. I've just only learned that if you wish to share a single fibre channel extent with many servers you need to use a clustered filesystem to prevent data corruption.
