Title: Message
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:

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
