parity check guide from unraid team?

[repomanz]

Hey team,

 

I had two back to back unclean shutdowns recently and I'm in the process of running parity check.  @58% it's found 3126 errors.  I suspect this may have been from the 2 unclean shutdowns.

All drives in the array are not reporting any errors and when it completes I assume all parity related errors will be fixed.  What guidance is available here from the unraid team?  I just shucked a new 12tb drive yesterday with the intention of growing parity drive ceiling but it's not in the unraid server yet.

We all know what "assume" actually stands for  

 

The only way to really know if your parity issues are fixed is to run a non-correcting parity check after it's done.  If it comes back as zero, then you're good.  If not, then you've got hardware issues somewhere along the line.

point taken.  Will hold the parity swap until i get a clean check.

Ok - so it ran through, found 3126 errors but says "parity is valid".  I guess this means it was able to correct the parity errors?

So you've rerun it?  Maybe I misread what you were doing.    A check after an unclean reboot is non correcting by default, so nothing's actually been fixed yet

i forced the parity check as I knew i had some unclean shutdowns AND I am planning on swaping the parity drive with a larger one. It went through that parity check, after finding 3126 errors said 'parity is valid'.  I am running it again to ensure no errors found on the 2nd forced check.
