Okay, so, I was here a couple days ago about my backup Raid failing. I've wiped the backup raid, built a new clean volume, everything is good.

I turn on the main raid, followed by the backup raid, and then a third additional raid I have as extra misc. storage, all daisy chained by Thunderbolt 3. Main Raid > Backup Raid > Misc Raid.

Go to start copying data from my main raid, open a Finder window with my main raid, when Finder says my main raid is "loading" in the Finder window, and giving me a spinny wheel. Then, suddenly, I get a SoftRaid error that 4 drives on my main raid are degraded/missing. Just out of the blue. No errors or warnings for the disks on this Raid previously.

After I have about 15 heart attacks, I restart my machine, power up only the main raid, and my main raid seems to be loading fine now, still with no errors on the disks.

 

What happened? Could it have been an issue with the daisy chain? Thunderbolt connection? Mounting too many raids? I'm terrified to do anything at the moment for fear my main raid will encounter another error like this and then all my data would be killed. Only my main raid is powered up at the moment.

 

Log attached. Thanks in advance.

Your drives did hang:

Oct 02 16:48:18 - SoftRAID Driver: A disk (disk12, SoftRAID ID: 0892641D96BF1E80) for the SoftRAID volume "112TB ThunderBay Flex" (disk22) was removed or stopped responding while the volume was mounted and in use.

 

This is a Thunderbolt issue. Make sure the cables are tight. You dont lose data from an event like this, but the volume's directory could get damaged. That is about the worst. (and Disk Warrior would be able to fix it)

So its getting to understand what is causing the eject or hang. Most of the time it is the cable (you have sleep settings disabled, which is good). But it could be computer or enclosure, of course.

Okay thank you! Cable connection might make sense since I was sliding the raids around on my desk. I will make sure they are fully seated. Thanks again!
