dunklesexil Posted August 5 Share Posted August 5 Start off with the basics os version 6.12.11 Ok so this started a few months ago, I would logon to server and see there was a FEW drives in unassigned devices which turned out were duplicates of drives on the array. I would restart and when it booted back it would be fine for a few days or a week or something. Well now its widespread currently there's 10 of my 26 drives showing up in the array AND the unassigned devices. Everything seems to be working fine no lost data, now here's the kicker it just did a parity check and found 1500+ errors. Weird thing was there was no errors on the array. All the errors were on the unassigned drives duplicates. They aren't even "mounted" so i'm really confused by all of this. I backed up flash drive and shut down server took usb key to my main pc, well it seemed like it was causing issues with my desktop AH HA! got a new usb key put my flash backup on it swapped out the registration key boom same issues. Curious if anyone has any ideas what could be the issue? Ill Upload server diagnostics. Thankyou for any help or suggestions! thequarry-diagnostics-20240805-1327.zip Quote Link to comment
JorgeB Posted August 5 Share Posted August 5 Aug 3 19:11:34 TheQuarry emhttpd: device /dev/sdan problem getting id This means Unraid is detecting some devices twice, note that Unraid doesn't support SAS multipath, so connect only one cable from the server to the enclosure, and that should be resolved.

dunklesexil Posted August 5 Author Share Posted August 5 So I have a super micro server and the backplane which supports 24 drives has places for i think up to 4 ssf cables to my hba, youre saying I should only have one for the entire backplane? Quote Link to comment

dunklesexil Posted August 5 Author Share Posted August 5 The weird thing is I got this server case probably december of last year. I had never (noticed at least) it doing this until the last couple months. The server actually has 2 backplanes and only some on each one seems to pop up on the unassigned devices?

JorgeB Posted August 5 Share Posted August 5 Make sure you only use one expander from each backplane and that issue should stop. Quote Link to comment
dunklesexil Posted August 5 Author Share Posted August 5 Ok! Ill give that a shot. Will that slow down my speeds? Quote Link to comment
dunklesexil Posted August 7 Author Share Posted August 7 OK! so I unplugged the extra sas cable to the backplane today started up server PERFECT. Went several hours just fine. Check up on it later today, 2 hard drives "died" restarted server got it back online running parity check boom one of the same ones died again. Seems extremely....suspucious that its been running solid forever then 2 hard drives "fail" they didnt fail more like they was disconnected and it disabled them. Any ideas on what this could be? for the time being i hooked the cable back up letting it run the parity before...more drives fail and i actually lose data. I have several cables I understand first step might be to replace it but these were new and I dont feel like its the cable, or the backplane for that matter. The real odd thing is I didnt REALLY start having the hard drive issues going to unassigned devices untiil the latest 6.12.11 im kinda debatiing rolling back? Thanks! Quote Link to comment
