F4-425

I had a TRAID using 3x 10TB drives, then I added a 4th 10TB drive.

I can't remember now, but I think when I added the 4th drive I may have selected an upgrade to TRAID+ thinking it was just a more advanced version of the TRAID system. I now know it is actually double redundant parity drives, but I would prefer the higher capacity and only one redundant drive. The system has completed one full synchronization task and is currently still listed as just TRAID, and it looks like I could expand the volume BUT it has immediately started a new synchronization task and I'm worried it's converting to TRAID+

Is there a way to see what the sync task is doing? Or to cancel a sync task or TRAID to TRAID+ upgrade? I'm happy to use ssh terminal if that's possible.

You can enter the following command in the terminal to view the current array status:

Code: Select all

cat /proc/mdstat

okay, I think the raid has turned out the way I need it regardless - thanks for the advice anyway

Code: Select all

cat /proc/mdstat

It seems the current array is still TRAID, with only one hard drive's worth of redundancy remaining.
