The scrub started Sunday at 2:00am. Checking the logs I have disk errors on disk 2. I have a fresh spare ready. Can I stop the scrub to replace the disk without damaging the data? It’s set up with xraid2 with dual redundancy & RAIDar 4.2.31. If so what’s the best way to do this?rebooting the NAS should stop the scrub. If it does, then you can just hot-swap the disks.
You could also try just removing the failed disk with the NAS running. I think the scrub will continue, since you have dual redundancy. But it should complete faster because the errors will stop. After the dust settles, you could hot-insert the replacement.

- The reboot stopped the scrub & I was able to replace the bad drive & it’s rebuilding. Thanks for your help!
