How to format 64TB disk array in RHEL 6.3


Hello.

We just got a new server in our lab (we do all of our own IT support) and the beast comes with a massive disk array of 64TB in RAID 6.

We would like to mount the entire space as /data on the server.

The problem is I can't seem to format the disk space as either EXT2/3/4 because of the size of it.

Can anyone suggest how I might go about achieveing my goal?
LVM? Software raid from lots of smaller partitions? etc...

The machine is running RHEL 6.3 (64 bit).
It's an HP Proliant server with the P812 disk array.

Thanks in advance for any and all help

Ext4 should be able to handle volumes with 1 EiB, so a 64TB partition shouldn't make problems. Which error messages do you get and which command do you use for formatting?

Thanks for your replies.
I ended up formatting the disk as XFS.

TobiSGD: The error message was that the partition was too large?????
I don't know why I was getting this error message.

In the end XFS did the trick. I don't think I'll be taking a big hit in performance with XFS over EXT4.

Thanks again guys.

If you have large files XFS may even be a better choice.

Please mark this thread as solved using the thread tools at the top of the thread.
