July 25, 20223 yr good evening, filled my drives/share, and stop the array to add a hard drive that was excluded from the share. (which i realize after i didn't need to do) restarted the array and now a cache drive is missing. i also have a parity drive missing but i am aware of that as my hard rives have an issue with my lsi controller. my docker is no longer start and i can add any data because when attempt to i receive a catastrophic error. also, i am looking to do a case/mb swap to resolve my parity issue, in the mean time i would like to know how to continue with out data loss given my current error. thank you! nastradamus-diagnostics-20220721-0428.zip
July 25, 20223 yr Community Expert Parity was already disabled at array start, so before the 16th, btrfs balance is failing due to not enough space, reboot and post new diags before array start.
July 25, 20223 yr Community Expert There appear to be two cables connected form the same HBA to two different expanders, Unraid doesn't support SAS multipath, connect just one cable, or both to the same expander if dual link is supported, then post new diags and the output of btrfs fi show
July 25, 20223 yr Author ok wasn't expecting anything like that, i assumed i would be deleting data or changing values since it was full. i did my research to built this almost three years ago. it seems i have forgotten a lot of the basic things. however, if i am understanding you correctly, i need to remove one cable from my BPN-SAS2-836EL1 and/or add another HBA/LSI controller to the second cable.

EL1 is a single expander backplane, took another look and you have two HBAs, so looks like you have both connected to the same expander, use just one, you can connect both cables form one HBA to the expander for increased bandwidth, but don't connect two HBAs to the same expander, that can be done for redundancy when supported by the OS, Unraid doesn't not support that.
July 25, 20223 yr Author ive shutdown,removed the extra third sas cable and rebooted. Second cache is showing, posting diagnostic without array start. btrfs fi show nastradamus-diagnostics-20220725-1742.zip
July 26, 20223 yr Community Expert Solution OK, logs is clean now, first lets cancel the btrfs balance, to do that: mkdir /temp mount -o skip_balance /dev/sdj1 /temp If mount is successful type: btrfs balance cancel /temp then umount /temp Now unassign cache1, start array, stop array, re-assign both cache devices, start array and post new diags.
July 26, 20223 yr Author here you go , checked docker and it loaded! nastradamus-diagnostics-20220726-0331.zip
July 26, 20223 yr Community Expert Run a scrub on the pool to see if it can sync both devices, check output in end, check all errors were corrected, possibly some device issues with sdi, pool is also very full, should avoid that, try keeping it under 80% used, 90% tops.
July 26, 20223 yr Author thanks you, im going start to unbalnce the drives back to 80% as i was in the middle of including a new drive. i tried to look up scrubbing etc as the terms you mentioned were over my head. giv4n the current state would it be safe to do a mb swap before i do this, or after? i would like to also fic my parity situation while doing any other data integrity check.

Click on cache and there will be a scrub option, need to scroll down. 4 minutes ago, Olymoly said: giv4n the current state would it be safe to do a mb swap before i do this, or after? Should be safe before, but I would recommend after just in case there are some unexpected issues.
July 29, 20223 yr Author scrub and read check all passed with no errors, i added an 8tb drive and i've been moving data to allow for 10% free peace across all disks. question, my vms tab says "libvirt" service failed to start. do you know or see anything in the diagnostics that would cause this?Sent from my iPhone using Tapatalk

July 30, 20223 yr Author rebooted and added some drives to preclear, however docker is failing to start again, seems to be the same drive and now failed smart, old age. i hardened to have already ordered larger ssd for replacement cache drives that should arrive today to help either way. i just have to figure out the procedure to swap them. nastradamus-diagnostics-20220730-0156.zip
July 30, 20223 yr Community Expert Docker image is corrupt, you need to delete and re-create, before doing that run a scrub on the pool and make sure all errors are corrected, no signs of a device problem that I can see, at least in these diags.
July 30, 20223 yr Author oh no! does that mean i have lost all my docker app's data? how do i recreate/delete the docker image? ive scrubbed pool and didnt get any errors. hmm i will do it again and check error correction. thanks again for your help.
July 30, 20223 yr Author i wanted to increase my cache drive size anyways would it better to go that route, regardless of erros kn the pool. im guessing this pool needs to be fix either way before i move on to the new drives.

July 31, 20223 yr Community Expert Lots of uncorrectable errors, run another one and post the diags after it's done.
