I asked this earlier in the month, at present you can't, the resize
command will be released in ocfs2-tools 1.2.2.

>From sunil's last email about this, the release should be coming out
next month?

Subject: [Ocfs2-users] Is there a way to expand a formated ocfs2
partitionwithout loosi ng the data on it?

Hello

I have the feeling this may not be the right forum for the following
question, but I d like to try it here anyway:

This is the case:

I had a 3x72GB HDD  RAID5 shared external disk drives (HP MSA500),
totalizing about 145,6 GB of data.
I needed to increase the available amount of data, so I added a 4th 72GB
HDD and using HP ACU I expanded my existing RAID5 Array, I have now
about 218,5 GB available.

But this is of course not reflected in my partition table.  I had
created 2 partitions on my drives, both formatted with ocfs2. I also run
HP Mutlipath.
See the status here under:

[root at erasme ~]# fdisk -l

Disk /dev/md0 doesn't contain a valid partition table

Disk /dev/md1: 143.6 GB, 143675555840 bytes
2 heads, 4 sectors/track, 35077040 cylinders
Units = cylinders of 8 * 512 = 4096 bytes

My question is :
I would like to know how to resize my partitions to reflect the changes.
The problem is that I cannot afford loosing the data already on the
ocfs2 partition. (the database).
Is there a way to expand a formated ocfs2 partition without loosing the
data on it?

Thanks in advance for your answers,

Philippe Andries
