Oh wow, this is extremely valuable, thanks!!

Alright, looks like I know what to do now :) Thanks bmartino and AI

Great info! Thanks for this! I have enough backups of everything, so wiping isn't a problem at all. What are the advantages of the ZFS pool instead of the traditional array? The ZFS pool for cache makes total sense, but: Do I add 1TB to each cache in mirror: 2 x 1TB ZFS in mirror for docker 2 x 1TB ZFS in mirror for VMs Or do I merge everything in 1 big 4tb pool in let's say zraid1 or 2?

Hi all, After reading and watching a lot of content on ZFS and the new stuff in 7.1, I'm still confused on what the best path forward is. I currently have an Array with 2 parity drives that I'm in the process of growing (I'm merging an old NAS into my Unraid server). The array houses all my media (photos, music, videos), which will account for about 19 TB when all NAS migration has been done. I then have 1 SATA SSD for Frigate Camera footage, 1 NVME for dockers and another NVME for VMs. Again, here I will get another 2 NVMEs coming from the old NAS. From what I gathered, a typical Unraid array is still the way to go after 7.1, but I need to do something with my cache pool for sure. Can someone guide me on what would be the best way to structure my drives?

Well tried with Truenas, which gave me smart errors on 2 disks, so got rid of those. Then swapped the backplane board and I don't have the power errors anymore. Now all that's left are those I/O errors, so I'll try the PERC cable once it arrives. There is light at the end of the tunnel!

oh man that doesn't sound good, before I start ordering parts, is it worth trying with another distro like Truenas or something, just to rule out any software issue?

Yes it's a dell r730xd with 12 trays. a backplane issue you tihnk? Temps don't pass 27C

Here you go, thanks for the help with this, I'm at a complete loss unraid-diagnostics-20240320-2137.zip

Ha yes, more logic, started a new config, just repeated the array

Switched the drives to other bays no difference. I did a smart test on all drives separately, the 74CC threw a read error, nothing on the others Started over with a new config ,and it's completely different and completely random, look at the screenshot. I can't format the disks 1 and 4, disk 2 keeps erroring out.

Apologies, just noticed those entries, no that wasn't me. I've checked the server logs on lifecycle, it doesn't show anything of the sort. Last hard reset was on March 5th, there are 2 redundant power supplies, no way anything shut down without me doing something. Looks like you found something else that's pretty odd

That's my manual intervention when everything got stuck during a pre-clear, PSUs are fine iDRAC says everything is fine disk wise, any idea on what to check? Not sure how my RAM could be linked to this, I indeed skipped the MEM check, having 128Gb of RAM and fearing the 5 days of checks while still figuring out how to get things running I started hot swapping disks to get smart tests separately on another computer, identified 2 with READ errors, but the other 4 are fine. Unraid didn't have an issue with the 2 errored disks. The parity disk and the 9VV didn't raise a smart error...

Hi everyone, It's been a month now that I have been trying the most basic thing, get my array setup. Haven't even reached creating shares because of this and I'm getting very disappointed in the process. Sometimes it's the parity disk that doesn't activate, other times it's a drive that gets unassigned, it's simply horrible. I've attached screenshots and diagnostic file. I have so far: - reset the config twice, with reboots in between. - ran smart tests multiple times,sometimes all passed, sometimes it got stuck at 10% and had to reboot - ran preclear, got it to run successfully on almost all drives, but it also crashes midway and at 40h per drive I gave up - formatted, rebooted, rebuilt the array, rebooted, started the array, never any luck. I have nothing yet on my disks, so I'm not loosing anytime except a lot of time, but this is getting very frustrating. The problem is, with the smart tests failing to run, I can't even tell if I have a bad disk. The thing is, the disks came from a QNAP that was running fine, so I wasn't expecting so much trouble. Maybe the next thing I can think of, is removing the disks and running a smart test on another computer? unraid-diagnostics-20240317-0932.zip

Whelp, maybe 2 years later, but still wanted to say thank you, this was super useful
