Did you clear the IO counters? My guess if you expected the validate to clear the counters. They are independent. Validate resets all parity bits and assures the volume is readable..
Cheers, how do you clear the I/O counters and what is the 'combo updater' please?

Okay, found the I/O counter bit. Does this actually do anything to the data/ drives - as in, do I need to clone the 'cleared' RAID again please?

Okay, hopefully last question. The RAID that I validated twice, then removed I/O and error counters is still showing degraded/ failed but each single drive is not showing any errors.
Presumably the data is intact, and since I have just CC'd it across to another RAID enclosure, can I now wipe this original RAID and re-CC'd the backup across?

Okay, I chose 'recover failed disks' and it seems to be okay now.

Okay, so now I've several RAID 5 volumes in enclosures CC'd to several other RAID 5 volumes in other enclosures. Would I be better off doing 1+0, and if so, is there any easy way to do it please?

What RAID level depends on your need for speed/capacity/performance and redundancy. I prefer RAID 5, but if the data is truly mission critical, then RAID 1+0 is somewhat safer.

You can send a support file to support at softraid and we can take a look. Kernel panics can be difficult to troubleshoot, but we can see if SoftRAID was involved in the last IO to the disks, or if it was a graphics read/write, etc.

If your volume "was" in sync, before say a crash, then recover failed disks is fine.
What this command does is assume the volume is OK, then clears the parity data, then rebuilds it from scratch. this is a bad thing to do if you just replaced a disk, however!

Each disk has a status partition where SoftRAID stores things like IO error counters. That is all it is, a counter and does not affect data inside the volume in any way.
