Unraid v 6.12.10

 

I replaced my parity drive with a larger one, and it's currently rebuilding. My cat stepped on the server's off button half-way through, and I was expecting to have to re-start the rebuild when the server booted again. However it appeared to pick up where the rebuild left off, and will be done in the next few hours.

 

So should I be confident that the parity rebuild is good to use even though it was interrupted by an unexpected shut-down, or should I immediately run a parity check when it finished rebuilding?

Thanks!

Stock Unraid would start over, I assume you are using the plugin?

With stock Unraid I would expect it to start again from the beginning.    The Parity Check Tuning plugin provides an option to restart from point last reached, but only if there was a clean shutdown which I would not expect if the system suddenly lost power.

That's helpful - thanks all. I must have mis-interpreted what I saw when it restarted. It's just finished rebuilding parity on an 18TBC drive in about 30 hours - not bad going.

Good to hear you are now good to go.

 

Since parity checks would take the same amount of time as a parity build you may well find that the Parity Check Tuning plugin would be useful to allow you run the check in increments outside prime time spread over several days to minimise the impact on you while actively doing things on the server.
