[Drive pool losing assigned letter when adding drive]

With SATA, is it possible to add a drive while the system is powered(hotswap), or is it card/mb dependant?

[Drive pool losing assigned letter when adding drive]

I was having a problem with my 2TB green drives and the head cycle count, so I started pulling out drives out of my pool, and replacing them with a spare, one at a time, so I could remove the timer in the firmware.

The first one removed no problem, drivepool removed the data from the drive, I put in a new 3TB red, and added it to the pool. No issues.

A couple of days later, I do the same thing, but I put in the green I pulled out. This time though, when I rebooted the server, errors started popping up, and the drive pool had changed from F: to L:, so all my shares disappeared, including my NFS shares.

I pulled out the new drive, rebooted, same issue.

I had to go into the "Manage", and reassign the drive from L to F, and reboot, then re-add the shares.

Anyone else seen this?  I had added other drives in the past, with no issues, the pool stayed at F:, for some reason today, it changed.
