January 28, 20251 yr Author OK, so it seems I have one SATA cable coming out of my modular 750 gold power supply that ends in with a 3-way SATA power daisy chain. I then added a 4-way SATA power splitter (which I had modded to a 5-way) to each one of those. So it seems for the last 6 years that I've been running between 10 and 15 drives off of a single SATA cable . . . Edited January 28, 20251 yr by beatmurph typo
January 28, 20251 yr Author OK, so I pulled out the box with all the odds and ends from my server build and found enough cables to separate the drive power down to 4 drives per power cable. The server has been rebooted and all the drives are recognized. The 2 drives that were disabled Sunday night both returned extended SMART scans with no issues. Since I've not made any changes to server content and had the array and docker off most of the time, I'm curious if there is a way to reintegrate those drives without either rebuilding them or parity? Or is that unavoidable?
January 29, 20251 yr You could New Config/Trust Parity, but then a correcting parity check should be done since something is out-of-sync. Technically it is the disabled disks that are out-of-sync, and if you don't rebuild them you would lose any writes done to the emulated disks while the disks were disabled. It's even possible that some of the missing writes would result in some filesystem corruption.
January 29, 20251 yr Author Thank you Turl & JorgeB. I think I have gotten to a good place. I did some research on this topic and found a thread indicating that while it seemed this would be safe there was also a threat of corruption as you mention. I wasn't sure if it was best to take that chance or the risk of another drive unmounting during a rebuild, but ultimately decided to go with a rebuild of the 2 unmountable disks. That rebuild just finished about 30 min ago. I also added some disks I did preclear on over the weekend. It seems that worked, as they are showing as available space on the array instantly, except for one of them. I'm not sure why, but that one is in the process of being cleared now *shrug*. Again, I can't thank you both enough for this help. Every time I go through one of if these fiascos I learn some new stuff and my server comes out a bit more stable. I can't say it's ever fun in the moment, but your support really helped ease the process.
