Did I get the whole concept of FlexRAID wrong?
« on: November 12, 2017, 03:49:00 pm »
I setup a FlexRAID storage pool with DRU1 (1x 4 TB HDD), DRU2 (2x 2 TB HDD), DRU3 (1x 4 TB) and 1 PPU (4 TB). Recently, one of the 2 TB HDDs in DRU2 failed. I did a swap-and-restore operation, but FlexRAID reported an error: "too many failed devices = 2" and the maximum of failed devices would be 1. The second disk in DRU2 works just fine. What did I do wrong? Did I get the whole concept wrong?

Essentially, yes. It should work, but doesn't. Product hasn't so much as had a bug fix in 2 years now - it'd dead Jim. I had this same error, as did quite a few other folks on the forum. You can read more about it here: http://forum.flexraid.com/index.php/topic,49386.0.html

But the short version is, your data is gone, and there's nobody to help you out. I suggest you move all your data to something that is actually routinely bug fixed and and supported, where you can actually get help if you need it. A standard RAID card, Windows Storage Spaces, a Synology, etc - anything that is known to work, with a large community, etc.

Best of luck.

The logs should have more hints on what's going on.
More likely than not, the RAID is out of sync with many deleted files on another DRU. See: http://wiki.flexraid.com/2011/10/18/understanding-the-limitations-of-snapshot-raid/
