RAID 5, Degraded - Missing Disk

Hey Everyone,

I have SoftRAID for Thunderbay v 5.5.6 on a Thunderbay 4, connected via Thunderbolt 2, running four Toshiba 6TB disks in a RAID 5 configuration (I have two RAID volumes). Everything seemed fine, but when I upgraded to v5.5.6, I got an error message, and both volumes reported that disks were missing (and the missing disk seemed to change). I did not remove any disks (it's a 4-disk external array).

Since the error message, I verified the disk that is no longer associated with the RAID volumes, and it has no errors.

I'm not sure what to do now. All 4 disks in the Thunderbay are identical, and none are reporting errors ... How do I "reintegrate" the "missing disk" back into my RAID 5 array?

I'm running a 15-inch MacBook Pro (2016), MacOS 10.12.6. The Thunderbay 4 is connected via its Thunderbold 2 interface, and I have an apple Thunderbold 2 to Thunderbolt 3 converter so it can connect directly to the Mac.

From the SoftRAID software, I went ahead and generated a "Report for Tech Support" ... but I don't know if that was automatically sent or what. (it created a file and saved it to my desktop, which I tried to attached to this post (but couldn't) - do I need to email that to you guys?)

Thanks for the help!

You need to send the report to support at softraid. We will take a look.

Was there any resolution to this query that might apply to the rest of us?

Cases like this, where the partition maps on disks are damaged, need to be handled individually.

In this case, two disks ended up with identical identifiers and we walked the user through the process of fixing his volume.
