Adding drives

[Robotbeat]

I think you can do this, but DEFINITELY backup your data beforehand! We had a customer that almost lost all their data this way.

Yes! I'll backup every volume into tapes just in case Mr Murphy decides to pay a visit.

I just wanted to know if it was a task that I should schedule for the weekend or if a single night would do.

From what I see from the previous posts a single night maintenance will do, but I wellcome more opinions/experiences.

Thanks!

Hi HangaS

The part that will take the longest will be the data migration when adding the new drive.
I cannot tell you exactley how long it will take, it will depend on the size of the drive.

you should add the new disk in this order
add the new disk to the array with your 3ware utility
(the data migration will take a long time, go Have dinner)
then use the PVresize utility in ctrl-alt-x
then the disk should be good to go.

I think you may need to reboot after the pvresize

I've done it a couple of times without data loss

good luck

Hi,

Thanks I already did it.
The migration took a very long time indeed. a couple of days for a 1TB Hitachi drive.

The only thing I was not expecting was that NSS reseted all my connections. And some NFS shares did not came back ok. :S
