Before doing anything of this type back up your information to different media and also validate the back-up using sha1sum.

The procedure from there would certainly resemble

• Break the RAID1 matching to make sure that among the drives is free
• Create an abject RAID5 out of the new drive and also the one without the RAID1
• Copy the information over to the RAID5 quantity
• Add the RAID1 disk to the RAID5 quantity, and also offer it a lot of time to integrate itself effectively.
• Validate that the information on the new quantity matches the back-up

I've thought that you're making use of Linux's software RAID assistance, in which instance every one of this would certainly be taken care of by the mdadm command.

Many wonderful RAID controllers can take a RAID 1 array, and also when you add an additional drive, permit you to transform it on the fly to RAID5, certainly, currently two times the size.

The AMI/LSI based controllers have been doing this for a couple of years (is it a years yet?). Dell PERC's, Compaq/HP's Smart Array controllers have actually usually made use of these chipsets.
