January 16, 20251 yr Im not sure if its my LSI controller or my external DAS and its connections but since unraid 7 and uninstalling nerd tools - it says i have drive errors - then when i put replacement ready to go (already zerod and formatted) drive - it then has really really slow write speed from other drives to try and rebuild drive - i dont think it was faulty drive.... I did a diagnostic and because i didn't want to mess with anything - i turned server off (for now) Anyone else exoerience anything like this since uninstalling U7 and Uninstalling NERD Thanks Ric
January 16, 20251 yr Community Expert Without diagnostics someone like Jorgeb won't be able to pinpoint the actual error here so suggest getting that attached if possible. My input is to check your cables, both data and power. I've had those thin blue data cables get really finicky when being wiggled even when the sata/sas port is connected good.

January 16, 20251 yr Community Expert Don't see any read or write errors so far, do see a reset error with party, this is usually a power/connection issue: Jan 14 12:47:16 Chip kernel: sd 10:0:0:0: Power-on or device reset occurred Also see problems with the pool, both devices dropped offline in the past, run a scrub and post the results. Jan 14 12:36:56 Chip kernel: BTRFS info (device sdb1): bdev /dev/sdb1 errs: wr 10234409, rd 18641, flush 0, corrupt 11554, gen 0 Jan 14 12:36:56 Chip kernel: BTRFS info (device sdb1): bdev /dev/sdc1 errs: wr 59873958, rd 215010, flush 1936768, corrupt 28667, gen 0
January 16, 20251 yr Author ahh the resets are because my server became unresponsive when copying some files over network a few times, so power cycled it... again i think this is to do with controllers etc will turn it on and do a scrub
January 16, 20251 yr Author ok, so those sdb1 (sdb1 and sdc1) are my cachepool Originally i had "Cache" then i created a new one called "Newcache" and got rid of old one - a while ago now See attached Screenshot of Scrub
January 16, 20251 yr Author I am now data rebuilding onto that new drive (16tb) and the old drive i will remove and inspect and afterwards - run a preclear and fully zero it to make sure its ok - then re-add it to a pool - or use it for something else... I have now set up a monthly scrub too Once the drive is all rebuilt, and thats all done I will be re-checking all cables being tidy and organised along the way In fact once its all done - i will come back and ask how i can re jig this so its neater (attached) I unbalanced and removed old 4tbs ages ago and bought a few 16s - so i have basically gaps Disk 2 Disk 3 Disk 4 etc i wanna rejig it so i dont have gaps is it just a case of stopping array and making new config? but with the checkbox to Preserve current assignments: ?

Likely win a parity rebuild in the process. I have some skipped disks from the same scenario. I force myself to leave it alone and call it mental toughening.
