I upgraded to 6.12.6 this morning from 6.12.4. When I rebooted, 8 of my drives showed missing.  I tried rebooting again, but no luck.

 

I've attached my diagnostics from just after the upgrade.

 

I have downgraded back to 6.12.4 to try and get my system running again.

 

EDIT - Downgrading didn't work. Upon reboot the drives were still missing.

He disks are not being seen at the SMART level in the diagnostics.

 

is there anything the disk having the problem share?    If so that may well be the cause of the issue.

Looks like power or controller problem. Are these disks on the same controller? Any power splitters?

I'm just starting to dig around in the case. I think they may all be on my HBA.  I can't verify until I check the serial numbers against the list.  But, if that is the problem, then could the update have messed with the HBA drivers?  I'm concerned that they didn't come back online when I downgraded, if it is a drivers issue.

No - if downgrading does not fix it then it is almost certainly a hardware issue.    If you think all the drives are on the HBA check it is properly seated in the motherboard, and no cabling to it has come loose.

Alright, so I'm back up and running now. I don't know why exactly.
I shut everything down so I could pull each drive and mark it's location on my spreadsheet. I checked the HBA, it and its cables seemed fine. 

I went back to my list of 'missing' drives. None of them were on the HBA. All 8 drives were in one external USB enclosure. 

I'm guessing that when I powered down the enclosure to get at the drive serial numbers, it reset something in it, and let unRaid see them all again.

I successfully upgraded back to 6.12.6.

USB not recommended for array or pools for many reasons. Don't be surprised if you have additional problems in future because of this.

Yeah. I know. It's my current only way of getting the extra drives into the array.  I've been running this for over a year now and never had that specific problem. I get that it is risky, and I'm willing to accept that. In the meantime, I'm slowly saving money to get a larger case and a few more HBA's in order to move all the drives to an internal configuration.
