February 6, 20242 yr I have been getting slow response for a while when accessing certain items. but i now have a failed disk apparently. I read some other posts here before doing anything so i have not restarted the machine yet. Diagnostics attached. if it is possible for someone to educate me on how to read these if thats possible. nas1-diagnostics-20240205-1102.zip
February 6, 20242 yr There are constant ATA errors for disk1 and the disabled disk, check/replace cables (including power) and post new diags after array start.
February 6, 20242 yr Author so before i checked everything the array was saying device disabled contents emulated. now it just says disk empty. Have i lost my data? Edit. nvm i disconnected the disk and stopped the array i can see the error saying content emulated now. I am rebuilding with a new disc. this one seems to be the issue. i may do the same with disk 1 also as you mentioned that was showing disconnection errors. Edited February 6, 20242 yr by Driden
February 6, 20242 yr Emulated disk5 has plenty of data, rebuilding looks fine so far. Don't see any reason to rebuild disk1 if that's what you mean. Do any of your disks show SMART warning ( 👎 ) on the Dashboard page?
February 6, 20242 yr Author i just meant about rebuilding disk 5 not disk 1. i think the disk 1 errors might have been a bad sata cable. the only one that shows an error is the disk 5. is that the new one? or left over data from the old one?
February 6, 20242 yr Author i think those last diagnostics should be from after that disk was added. done again just in case nas1-diagnostics-20240206-1907.zip
February 6, 20242 yr Disk5 warning is 199 UDMA_CRC_Error_Count -O--CK 200 200 000 - 47 These are connection problems. Could be old and not a current problem. Click on the warning to acknowledge and it will warn again if it increases.

Unrelated Why do you have 200G docker.img? Have you had problems filling it? 20G is often enough, maybe a little more if you have a lot of dockers. But usage shouldn't grow. The usual cause of increasing docker.img usage is an application writing to a path that isn't mapped to host storage. Also, your system share has files on the array. Ideally, that share, along with appdata and domains, should have all files on fast pool such as cache, with nothing on the array, so dockers/VMs will perform better, and so array disks can spin down since these files are always open.

All rebuilt as of this morning with no smart errors. i will keep an eye on the dashboard in case it appears again. I think i may need to replace a few hardware components in this build altogether. the network seems to be trying to run at 100mbps even though its a 1000 nic as is the switch it is wired to. and i know when i first set this all up there are at least 2 sata ports that cant be used if i use the single available m2 slot. its just an old 350 gaming 3 mobo from my old desktop so possibly time for an upgrade of the main hardware anyway. it only has one usable pcie lane other than the gpu which i do use for some transcoding. so i have the sas splitter card in there and thats me done using the onboard nic to communicate. i have 2.5g networking in the opnsense box so should really get a 2.5g nic in this and wire directly to that i suppose. In ref to Docker that file can probably go. I do a lot of experimentation with various AI and image recognition projects. a lot of which have little to no documentation in terms of what could be using a mounted volume. this is probably left over from me trying to get a docker compose to run and get a functioning product so that i can then determine what folders should have a -v to an appdata folder. I very very rarely use a VM to just serve a specific purpose which it then would be turned off after. is the system folder specifically used for all docker images then? and would always benefit from being cache based? ill clean up the old images and assign that to the cache. once i have put a heatsink on the nvme. as it regularly hits 70C, which is partly why i havent pushed the cache assignment any more. the server is nice and responsive for the main things i use it for, but more performance cant hurt can it !! I dont fully understand the caching part in terms of whats best to assign. i will read up more or find a space invader video to go through. And I will assign the system folder in the meantime. nas1-diagnostics-20240207-2101.zip

Check ports, plugs, cables on switch, router. 1G degrades to 100M if just one wire is missing. 8 minutes ago, Driden said: is the system folder specifically used for all docker images then? That is the usual path for docker.img as you can see in Docker Settings. 12 minutes ago, Driden said: dont fully understand the caching Your Minimum Free for cache may be a little high, probably set automatically because you hadn't set it. It should be larger than the largest file you expect to write to cache. If the cache gets below Minimum Free, new files are written to the array (overflow) for shares that have Secondary storage set. 15 minutes ago, Driden said: assign the system folder Settings for that share are OK, but some of it got created on the array, maybe you had Docker and/or VM Manager enabled when cache was missing or not yet assigned, so they got created on the array. Nothing can move or delete open files, so you have to Disable Docker and VM Manager to clean that up. And mover won't replace files, so if something exists in both places, you will have to decide which to keep. Or just use Dynamix File Manager plugin instead of mover.
