Big Sur is NOT compatible with Terra-Master D5 thunderbolt.
I tested it first with my laptop on Big Sur and it mounted and worked ok. Then I updated my iMac to Big Sur and connected the D5. Initially, it was ok, working fine mounting my raid drive 70TB in total.
Then after half a day - it failed the raid array completely. There is nothing wrong with my drives, the D5 and was working fine yesterday under Catalina.

Big Sur
Re: Big Sur
I can confirm the same on my D4, working flawlessly, then upgrade to Big Sur last night and now failing, we need this fixed ASAP and disapointed that nobody tested this with any of the betas over the past 3 months
Re: Big Sur
I've logged a support ticket with Terra Master - support(a)terra-master.com and also with Highpoint-tech who make the Raid controller: https://www.highpoint-tech.com/websupport/
Re: Big Sur
After update from Catalina to Big Sur, please try to re-install the RAID driver and RAID manager pro on your MAC.

Re: Big Sur
For new customer, the newly purchased D4/D5 Thunderbolt 3 can be configured and work well on Big Sur. BUT for those who has been using the device on Catalina for a while, this could be a challenge. If you found your D4/D5 RAID system does not support by Big Sur, please try to re-install the RAID driver and RAID manager pro. If that still failed, you may have to rebuild your RAID on Big Sur, that means you will lose your data, please backup your data before you do that.
One thing need to be clear, if a device has been well set on Catalina and working well on Catalina, but Big Sur does not support it, this is Big Sur problem, not the device's problem!

Re: Big Sur
By the way, when your D4 failed on Big Sur, what message prompt to you? may I have more specifics how it failed?

Re: Big Sur
When it fails I get the following message, I have tried reinstalling the driver and the raid pro manager. It isn't always the same drives, the drive or drives that fail is random.

Re: Big Sur
As a follow up to this, I have found that if it keeps failing, if you keep powering off and back on the Terra Master until it completes it's rebuild process, mine took 2 1/2 days, it will then reset it's status to normal and operate correctly.
Re: Big Sur
I spoke too soon, after about 2 hours it failed again, and started the rebuild process at 0%, so yeah we need to find a fix for this
