Full Discussion: Increase Linux partition size
Operating Systems Linux Red Hat Increase Linux partition size Post 302492291 by STOIE on Sunday 30th of January 2011 11:27:09 PM

Option is this:

Create a new partition same size as the old one.
Copy contents to it.
umount the old one, mount the new one... (a few seconds downtime)... will have to bounce services.
Expand the old partition:
fdisk /dev/cciss/c0d0
d
u
u
p
n
p
1,2,3,4???
start
end
w
q
resize2fs /dev/cciss/c0d0p9
fsck.ext3 -f /dev/cciss/c0d0p9
Then umount the new partition, and mount the expanded old one. (a few secs and service reboots again).

What would be so much more easy, is if you can provision a new partition then just mount it in the same location, however, your device path will have to change. (if that matters)

On the other hand, if you want to change things "live" live, then you will need something like zfs

mkfs.bfs

MKFS.BFS(8)						Linux System Administrator's Manual					       MKFS.BFS(8)

NAME

       mkfs.bfs - make an SCO bfs filesystem

SYNOPSIS

       mkfs.bfs [-N nr-of-inodes] [-V volume-name] [-F fsname] device [size-in-blocks]

DESCRIPTION

       mkfs.bfs creates an SCO bfs file-system on a block device (usually a disk partition or a file accessed via the loop device).

       The  size-in-blocks  parameter  is  the	desired size of the file system, in blocks.  If nothing is specified, the entire partition will be
       used.

OPTIONS

       -N     Specify the desired number of inodes (at most 512).  If nothing is specified some default number	in  the  range	48-512	is  picked
	      depending on the size of the partition.

       -V volume-label
	      Specify the volume label. I have no idea if/where this is used.

       -F fsname
	      Specify the fsname. I have no idea if/where this is used.

       -v     Be verbose.

EXIT CODES

       The exit code returned by mkfs.bfs is 0 when all went well, and 1 when something went wrong.

SEE ALSO

       mkfs(8).

AVAILABILITY

       The mkfs.bfs command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
