gparted fails to grow partition

[captainentropy]

Hi everyone,

So, I have a machine running Ubuntu Server 9.10 installed on an 80GB RAID1 disk. The system has two arrays (one data, the other backup), each of the same size in RAID6 with ext4 fs, connected to separate 3ware 9690 controller cards. I had to increase the size of the arrays from 8TB to 12TB. No problems - added the drives, migrated the new disks into the array, rebooted the server, and everything is visible. I unmounted the drives and then attempted to grow the partition (it's a single partition), starting with the backup array, using gparted. It sees the unallocated space but when I try to grow the partition into the unallocated space it fails. Here's the gparted error details:

libparted messages ( INFO )

The backup GPT table is not at the end of the disk, as it should be. This might mean that another operating system believes the disk is smaller. Fix, by moving the backup to the end (and removing the old backup)?

Not all of the space available to /dev/sdc appears to be used, you can fix the GPT to use all of the space (an extra 7812456448 blocks) or continue with the current setting?

Unable to satisfy all constraints on the partition.


I'm not sure how to proceed with the libparted info and I can't find any useful information for me anywhere. I hoping the experts here can help me :D

Thanks for any help you can offer.

nobody? I'm getting desparate here. I need to get this server online with the added capacity. I have no idea how long it will take to complete registration on the gparted forum to ask that community (it's taking a looong time).

I've repeated this using a liveCD and the results were the same.

I ran parted on it and it sees the disk as 12TB but after following the tutorial here http://wiki.linuxmce.org/index.php/GPT for resizing a partition table it still reports the end point as 8TB. ???

ok, even though parted reported 8TB I ran gparted on the drive and it grew the partition to 12TB. All is good now. All the data is there. I repeated this for the data array and it too is good.

Thanks me for helping me.
