Topic: Raid1 drive upgrade

[tcarroll]

Good evening all.  I am running a fairly customized SME 5.6UDR (U4) and have recently purchased two new Seagate 300gb HDDs.  I would like to replace the two WD 100gb HDDs without going through a new install.

I have had no luck using the built in SME backup to desktop.  I have looked at the BackupPC option also but was wondering if there is a way I can just pull one of the 100gb drives, insert the 300gb drive and let the system build it as if the 100gb drive failed.  Once the rebuild is done, remove the other 100gb drive and insert the other 300gb drive and allow the raid software to rebuild it to match the other drive.  The problem though is that the partitions would only be 100gb - right?  Maybe I should use a disk utility to expand the partitions out to the 300gb range?

Is this crazy, or will it work?

Thanks!

Ok. Im assuming you mean raid1 as raid0 is just two disks with different data written to them (no redundancy)

You possibly could pull one of the drives under raid1 but the partition table would need to be the same as the  old disk so what you would end up with is a copy of the 100GB disks and 200GB of unpartitioned space which you would need to create a new raid partition on.

Not so much fun.

Im not sure if swapping out the disks then running an upgrade in place would expand the / partition. Perhaps someone else would know?

cheers

Thanks Patrick.

I am curious if I could use Partition Magic to expand the partitions out to 300gb after having the two drives rebuilt by the raid software.

And yes, I did mean Raid1...

Im not sure how partition magic works with software raid, but it possibly could work.

I would test it on a non-production system first.

sorry I couldnt be of more help.
