preclear of 1 disk and parity check was running. the system locked up and i had to hard reboot. been happening for 2 days and so i log to the usb thumb drive and see the above.

syslog(1)

That's the Unraid driver, only LT might be able to help with that.

I'll ask again... What's the unRAID driver 2.9.17?

 

Just trying to understand things. I'd like to know what "md:" and "kernel:" mean as well?... I think I know the kernel is the "core" OS. What is "md:"?

 

@etegration please remove your syslog file. (Or maybe a mod/admin could?)

The UnRaid driver is the one that Limetech provide to handle array devices which when in use are mounted with names of the form /dev/mdX (where X corresponds to the disk number.   ‘Kernel’ is the underlying Linux.

Thank you itimpl!... That makes perfect sense (drives can't "parity" themselves :)... I really hate to ask, but... what is, "md:"?

 

If I said, "Enquiring minds want to know"... Would you laugh?... 

 

I don't know what "md:" is. Live and learn.

It is the name that Linux developers for some obscure reason used to refer to array devices under Linux.   Limetech re-purposed the standard Linux array (md) driver with their own special variant.

According to this man page, md stands for "multiple device".
