Greetings all (and Thanks in advance for any and all feedback).

I've currently got a Pegasus2 R2+ with 2 3TB Hard Drives in a RAID1 (mirrored 3TB) configuration. I'm considering a drive upgrade, but wanted to gather some info before I went forward with it. Here's my questions....

1.) Is it possible to upgrade 1 drive at a time (i.e. remove the secondary drive, install a new drive and wait for it to populate then install second drive and wait to populate)?

2.) Is it possible to migrate to a new RAID configuration (i.e. convert from RAID1 to RAID0) without losing all of the data? My assumption is that the mirrored drive would lose all data as the migration progressed, but the original drive would stay whole.

My apologies if these are basic questions. I'm relatively new to the RAID game. ;)

Hi Eric,

Thank you for choosing Promise Technologies, Inc. for your storage needs.

1. The best way to upgrade the drives to make a new array with large capacity drives to get the full space otherwise, if you replace one drive at a time, the volume space will be truncated to the same size as your current 3 TB drives. So if you have a data backup. (everyone should backup critical data), you can just make a new array and then copy the data to the new disk setup. If you don't have a backup, It is best to backup all your data to another location, then make a new array and then restore your data.

2. We don't have migration option on the Pegasus2 R2+ unit.

We are sorry for the inconvenience caused.

Thank you.

Thanks. I was pretty sure that that was the direction it was going to have to go.

I swear that I read this and thought, "Wow, I've already uploaded my 2 questions!" As it turns out, it was you, not me, that posted my questions! :)
