SoftRAID Volume Locked error
Here is a test you can do. Run AJA Systems test (free on app store for Lite version)
Set video to 5K, file size to 16GB, codec to RGBA, select your volume over ethernet and run a test.
then click the "graph" icon, to expose the chart. If you have an ethernet issue, you will see full periodic dropouts. Otherwise, it should be reasonably consistent throughput.
Thanks for the tip. I ran AJA System Test Lite from the Mac App Store and also Blackmagic Disk Speed Test and the throughput is consistent, but not as fast as I'd like. I have jumbo frames enabled on my Mac and on my network, and the connection from my Mac to the 10G switch is using a pair of Cat 6 cables with the interface set to 10Gb/s in a Link Aggregation Group for load balancing. The connection from the switch to the NAS is using a pair of SFP+ DAC cables also set to 10G/s in a Link Aggregation Group. The NAS may just be busy indexing and doing other tasks (it seems to be faster just after a restart), but I'll keep monitoring it. I'm planning to add an SSD cache that will further speed things up.
Regarding the SoftRAID issues, I'd like to report one more. I was running Clean My Mac today and I noticed that at some point SoftRAID 6.2.1 had installed a broken login item on my Mac. The file in question is /Library/LaunchDaemons/com.OWC.HelperTool.RepairSRTool.plist. I opened the file in a text editor and it references a non-existent helper tool with the path /Library/PrivilegedHelperTools/com.OWC.HelperTool.RepairSRTool. Just thought I'd mention this in case engineering wants to address that issue as well.
Sometimes blades (especially after getting hot from use) fall into a state where the unit needs to be power cycled, or powered off for a little while to get them working again. I think something like that happened.
This volume locked error was first reported here in August 2020 and it is still not resolved. Apparently there is a new driver but I do not dare load it in case it causes my external drives to crash and I waste time again.
SoftRAID keeps blaming Apple for causing the issue. Surely the CEOs of OWC and SoftRAID can put a call into Tim Cook and get him to get this problem sorted (or find out whether it is actually an Apple caused issue). If they cannot get to Cook then it shows that OWC and SoftRAID have no cache with Apple.
There was a component of the volume locking that was a "false alarm", fixed in 6.2.1, which you may want to try.
remove your disks, uninstall SoftRAID driver, then install 6.2.1 and make sure you "Allow" OWC again.
If you keep getting this, yes it is the hardware issue and while Apple engineering is "working on it", we have not had resolution, no.
We do not have a line to Tim Cook, no. But we do communicate directly with the kernel team.
@softraid-support Thank you the update. I've too much important work at the moment to experiment with a replacement driver.
If it is an Apple problem then the problem needs to be escalated above the kernel team as they have had enough time to fix their problem.
I'd just like to add that I have eliminated the SoftRAID volume locked error and sleep issues on my Mac by fully removing the Thunderbolt enclosure from my system and moving the disks to a NAS. I'm very happy with the performance I'm able to get over 10GbE and SMB3 with both encryption and AFP disabled on the NAS.
