Hi @JorgeB I have just had my server crash and have attached diags, is this related to my other crashes you helped me with last week? the server is on 24/7 and this is the first problem since the possible RAM issue/corruption I had last week. Warning: mkdir(): Input/output error in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 351 unraid1-diagnostics-20230221-1113.zip

Hey @KluthR All done, my backups were ok and not broken but I changed my USB location as you advised. I do think the problem is physically reading the files mentioned in Nextcloud, do you think that could be the problem as it still fails. backup.log

Attached, thank you! BackupOptions.json

Hi yes, I have run a couple of manual backups trying to diagnose the issue.

Many thanks! backup.log

Hi, Can anyone please help me out with what could be causing the input/output error I am getting with CA Backup on my Nextcloud container?

Thank you, I will read through this to better monitor the pools, again, huge thanks for your help!

ok, so have scrubbed all 3 pools and no errors found on any of them!

Hi, which pool do you mean please?

Attached, many thanks unraid1-diagnostics-20230218-1125.zip

Thank you @JorgeB 1, I have run the memtest which passed but I have another 4 sticks which I have now replaced the existing RAM with. 2, You say there was existing corruption? how do I address that please? 3, Is this not an NVME problem then? "BTRFS error (device nvme2n1p1): block=161059291136 write time tree block corruption detected" 4, I will look into ipvlan now. Thanks again!

I also, just saw this in the log when I started to shutdown after I took the diags Feb 18 09:48:42 UNRAID1 kernel: BUG: Bad rss-counter state mm:00000000ee5ad6d6 type:MM_ANONPAGES val:1 Feb 18 09:48:45 UNRAID1 kernel: I/O error, dev loop3, sector 83360 op 0x1:(WRITE) flags 0x1800 phys_seg 8 prio class 0 Feb 18 09:48:45 UNRAID1 kernel: BTRFS error (device loop3): bdev /dev/loop3 errs: wr 1, rd 0, flush 0, corrupt 0, gen 0 Feb 18 09:48:45 UNRAID1 kernel: I/O error, dev loop3, sector 188192 op 0x1:(WRITE) flags 0x1800 phys_seg 8 prio class 0 Feb 18 09:48:45 UNRAID1 kernel: BTRFS error (device loop3): bdev /dev/loop3 errs: wr 2, rd 0, flush 0, corrupt 0, gen 0 Feb 18 09:48:45 UNRAID1 kernel: BTRFS: error (device loop3: state A) in __btrfs_update_delayed_inode:999: errno=-5 IO failure Feb 18 09:48:45 UNRAID1 kernel: BTRFS info (device loop3: state EA): forced readonly Feb 18 09:48:45 UNRAID1 kernel: BTRFS: error (device loop3: state EA) in __btrfs_run_delayed_items:1092: errno=-5 IO failure Feb 18 09:48:45 UNRAID1 kernel: BTRFS warning (device loop3: state EA): Skipping commit of aborted transaction.

Hi, I woke this morning to find most of my dockers stopped, it looks like ca backup stopped my dockers ready to backup as the backup folder was created but it is empty and I can see all these BTRFS errors on nvme2n1p1 but I cannot work out which physical drive this is? This is the 3rd nvme related problem I have had on this new motherboard in as many weeks so really need to get to the bottom of it, any help will be greatly appreciated! unraid1-diagnostics-20230218-0934.zip

Hi, I feel I should know the answer to this but can I use the iGPU on my 13600K in a VM and dockers like Plex still have access to it?

Thank you for all your help @JorgeB @trurl

OK, so I carried out a repair and everything is now back looking like it should do but there is no lost+found folder on disk 10 so does that mean I have not lost any files?

Done! Sorry!

So sorry, I forgot to add the Diags! unraid1-diagnostics-20230210-1450.zip

Just this moment thought of something! Last week, I lost all my appdata on my cache drive, the physical drive is a Samsung 970 Evo Plus NVME, one morning I woke up and it was empty! I have now added 2 Rocket NVME drives to create a cache pool and the Samsung I moved to a secondary cache to handle caching for my shares including the TV Shows folder I am having an issue with. It maybe nothing to do with it but it does seem a coincidence?

Hi, Just as the title describes I cannot access one of my subfolders in a share but plex and other dockers seem to be able to? I have attached my diags, if someone could take a look I would really appreciate it! The folder in question is /mnt/user/TV Shows/tv This is a new build, upgraded motherboard & cpu about a week or so ago that has been running fine although yesterday I was unable to access any shares, stopped the array and restarted and all seemed fine but I suspect it was the start of this problem. Many thanks,

Thank you so much for your detailed reply and your blog looks excellent! I am looking forward to working through that later 🙂 I currently have 6 cameras (5X2K and 1X4K) and running Blue Iris I have a cpu usage of approx 6% but obviously there is no AI going on, just recording raw to hard disk and using low res sub streams to the web viewer. I am currently trialing Agent-DVR but really struggling with the interface, I can't be sure that it is doing what it should, it does not fill me with confidence so after some reading, Frigate appears to be the way forward. I will hold off on buying any acceleration as I have a 13600K CPU with iGPU so when the beta is available with iGPU encoding that will be interesting to test. Again, Many thanks for your reply!

Hi, I am very interested in this project as I no longer want to run a VM just for Blue Iris, 1, I have tried to install but finding the instructions very fragmented and not neccassarily relating to unraid, is there a step by step guide to unraid installation anywhere? 2, Do I need an accelerator? I have a 13600K, will I notice a large increase in CPU? Many thanks in advance!

Ever seen this before @JorgeB ?
