I've been using Unraid for years with little to no issues. i run a C220M4S head unit with 2 SSDs for cache in an HBA. I have 2 Netapp DS4246 shelves connected with 30 8TB drives. Ran this way for a few years now and all of a sudden after a sudden power failure/reboot i'm getting Kernel Panic -- Not Syncing: Fatal Error in inturrupt Kernel Offset Disabled -- end kernel panic -- not syncing fatal exception in interupt and that's where the boot process stops. I've tried to reimage with same version and newer version of unraid 6.7.2 and tried 6.8 with same errors using my config folder and fresh install with same issues. I tried swapping hba card thinking it might be that. I can get it boot 100% if i pull out expansion cables to sas shelves but then i don't have any disks and if i plug cable back in system goes unresponsive. Ideas, thoughts, helpful tips?

I have a Cisco C220M4 with 56 Logical Cores, 768GB of ram, 5 1.92TB SSD (in cache pool) and that's connected to 2 24-bay (Netapp DS2446) shelves via Netapp x2065 qfsp card. I'm using 24 x 8TB in one system and 6 x 8TB to complete my 30 disk (28+2) array. I have enough room to make a 48 bay array with the same connection and hardware setup. I know i could buy larger drives as you already stated but i have another 6 x 8TB drives, 9 x 6TB drives, and 7 x 4TB drives. I could always go with a freenas solution but with the mixture of different drive sizes and parity protecting i want a larger array. I'm aware i don't hold unraid accountable for any of my gear besides the OS working. When i tried to use multi-pathing it showed 60 disks instead of 30 (2 separate paths) but wasn't smart enough to show multiple paths to each drive. I would be willing to take on an "experimental" larger than 30+ "At my own risk" if at all possible. I do have 2 60 bay expansion shelves fully populated with 3TB drives that would love to use at some point but honestly i think 60 disks total in an array and i'd be happy since 8/10TB drives are in a happy price point right now.

I tried switching to official plex docker from the linux repo one and what finally fixed my issues was stopping the docker then going to /mnt/cache/appdata/plex/Library/Application\ Support/Plex\ Media\ Server/Codecs/ and deleted the 2 files out of the codecs. Then I restarted the docker and it redownloaded the codecs and bam everything is FINALLY working. Didn't have to revert the plex versions from the latest. Tested on both dockers with success.

I agree I used to run 3 servers with msa's attached and using Unraid have been able to get down to 1 24 bay supermicro running vm's. If I were able to put more disk into a single system with multiple arrays similar to glusterFS, or implement a way that I can break my 24 bay into 4 arrays that each take up a spot. I have 2 power cords, 2 ethernets, and 2 10g SFP+ from one box that can run to network or other devices when I expand.

I would love 5 12 disk arrays. I have the chance to get a netapp eseries 60 disk in a 4u chassis. It’s 5 shelf’s of 12 disks. I’m perfectly ok with 5 arrays and then it all be concatinated together. Food for thought I guess

I agree with you on those are must haves! After spending hours diving down the rabbit hole I realize this is a much debated thing but for some of us we want ability to run large “enterprise” type systems with easy to manage interfaces like unraid at home

For companies that use 45 or 60 drives I would love to see support for 60 data disks. Is there any thoughts on implementing this possibly a triple parity? bacn8r
