This is interesting. Started out at 6.6.2. Upgraded the other day to 6.6.3 after backup of flash drive. No problems at all.

 

Today I update (after backing up flash) to 6.6.4, and now I get random missing disks after reboot. The disks are there, bios & controller sees them fine.

 

GUI reports stale configuration.

 

Thoughts, anyone?

 

Edit: Now it's running fine. Restarted computer about 3 or 4 times and all the disks finally showed up. Started array. All is good. So far.

I know some errors in log files can safely be ignored, but this probably isn't that case:

Started going though log files and found this, it seems to be repeating depending on system activity. Looks like the errors are the same each time.

 

System is running properly though; parity check ran with zero errors.

 

Thanks for any insight into what this might mean.

You have some bad memory.

Check the board's system event log, it should identify the problem DIMM.
