Parity Logs Disabled but Healthy

[liynus]

Trying to figure out what happened to my Parity drive to disable it, can you guys clarify through the logs:

Thanks. Edited attached the logs.

I very much doubt that you are going to get anyone to try and work through the information you posted as it is unformatted and not amenable to being analysed.    You should include such information as an attached file (which hopefully retains its original formatting) if you want anyone to try and give you any useful feedback.

Looks more like a controller problem, you're using a Marvell controller with/connected to SATA port multipliers, either one is not recommended, and especially not both together, still good idea to run an extended SMART test on parity.

Forgot to mention, CPU is overheating and throttling down, check cooling.

And in case you don't know, you will have to rebuild parity (after you get your hardware problems resolved) to get it enabled again.

Thanks. This was a case from BackBlaze 2.0 which they gave out for free. It's sitting in my garage and it's summer, so I'm not surprised about the cooling. I'll probably turn on the fans. I'm a relative unRAID newbie. It's a long rabbit hole.

Can I ask how did you work out that it is a controller problem?

I said it looks more like a controller issue, you can (and should) still run an extended SMART test on parity to confirm, but even if the disk is the problem for now I would still recommend replacing that controller since it will likely cause trouble sooner or later.

thanks. finally got around to it today. I took out the controller cards and plugged all the drives directly into the motherboard. startup errors went away.

 

it's rebuilding parity now. was afraid i was going to lose my data, but your advice and spaceinvader video on xfs corruption saved my butt <https://www.youtube.com/watch?v=JVjB0ROdLBA> wife is SO happy about your unraid hobby.

 

also my docker was hanging my whole system, deleted the docker.img and just reinstalled, nice that the app data is separate, so all my plex data is unchanged!!

 

unraid is so powerful, but also so complicated for average nubes. it's a long learning curve at times for sures. thanks teeteejorge for all the work that you and others do on this forum. unraid's also a pathway to linux learning and learning to program in python for me. what a rabbit hole!!

also find it interesting this was a homegrown solution to have 48 drive for backblaze, perhaps they run proprietary software that compensates? any thoughts on what to do the controllers/port multipliers?

Recommend one or more LSI HBAs with SAS expanders as needed, you can reliably use many devices with these.
