How to use a SoftRAID startup volume with High Sierra

If you're using High Sierra, and booting up from a SoftRAID volume, you'll need to follow the steps given in this forum post, since the macOS High Sierra Installer does not recognize SoftRAID volumes as valid startup volumes.

Tried RAID on another machine, now all disk failed
#1
Hi all,

I have a Thunderbay 4 with 4x 3TB drives in there in what I believe is RAID 5. I always use it on my Bin MacPro (running macOS High Sierra 10.13.3). Apart from the day I set it up, I never had issues.

Today, I installed the SoftRaid Trial on my laptop to that my assistant can access the content of the RIAD without having to use my machine. Once the setup was finished, I rebooted the laptop, started softraid and plugged the Thunderbay. I started seeing a bunch of errors and got really worried. So I unmounted the volume, turned the lot off, and plugged it back onto my MacPro.

I'm now getting the same errors: All my 4 drives have "i/o Errors - data and parity disk - failed" in red. I'm extremely worried I'm losing all the drives in one go.

HELP!

You need to send a tech support file to support at softraid.

We will help you. Probably this is easily resolved.

Thanks!!

Will do asap then. For now I have turned it off as I’m away for a week from Monday onwards and wouldn’t want to risk the data on it to be corrupted.

Hi did this get resolved? I recently updated to High Sierra and now have three drives with same red warning. The machine locks up after about a minute, but is fine when I disconnect the RAID.

thanks,

Matt

You contacted us directly and note that you have three disks with reallocated sectors and thousands of unreliable sectors. I do not know what happened, but three disks are failing.

(Wonder if perhaps you bumped the drives when they were still powered on, or the enclosure was jarred enough to cause damage to the heads? that is a possiblity)
