One of my drives started having the odd read error last week. As its one of my older 4tb drives I shrugged and ordered a replacement drive.
Shortly after Unraid disabled the drive. No problem, iIhave dual parity and a replacement is on its way.
before the arrival of my new drive another drive became disabled.
My replacement drive is now here and I'm trying to rebuild the first of the disabled drive onto this new 8tb disk. However the rebuild gets to somewhere in the high 40gigs of rebuild and consistently hangs. Plex and LMS non responsive, Unraid web interface unresponsive and neither will the server respond to a simple ping.
A hard power off and restart brings the box back into the same state, array comes up and the rebuild begins again. hits 40 something gig into the rebuild and repeat.
Unraid Version is 6.8.2 , i was planning to upgrade this week but issues got in the way
Not sure if related but the week previously I had an issue with the logs hitting 100% utilisation and the CPU display on the summary page not working. Since the server hadn't been rebooted in over a year, I rebooted and both issues disappeared.
thoughts appreciated as I'm running on borrowed time with no protection at the moment
