hmmmm disk 8 seems to be having read/write errors on data rebuild. could just be a power issue. should i let the rebuild run its course and figure out disk 8 afterwards? tower-diagnostics-20230330-1505.zip

Yeah, Its asking for -L repair on the disk (5) im doing so now. Should i do the same for disk 14 if it asks for the -L repair. Once i finish this i should reboot or just start array and let it rebuild?

hi, I have done so and the parity seems ok now. Though disk 8 is now having read errors. i did not touch this disk. This must be coming from wire/card. I will investigate this further and post a new diagonostic. It has started rebuilding disk 5 and 14. Should i allow this? even tho they are in an 'unmountable' state? tower-diagnostics-20230330-1351.zip

I should add it is currently rebuilding right now.

Hi guys, This morning my server lost power. I believe the UPS saved it and put it into a safe shutdown. The same cant be said for the JBOD attached to my unraid server. Basically i have 2 drives that needed i file system repair which i did and restarted the array. The 2nd parity drive started to show errors I am not amazing at unraid and fixing disk errors etc. as you can see from my post history. But i do have a basic understanding I have attached my diagnostics. if anyone can chime in as to what i should do next it would be appreciated tower-diagnostics-20230330-1317.zip

Ok when doing new config do I “preserve any current assignments” ? again I really appreciate your help

I will only have one parity drive. Since one of my parity drives is 'missing/dead' Also I am still having the original problem of the Red X on drive 1 and 9, Both are present before i start the array. Can these also be repaired? or will they be emulated from the one pairty?

can you tell me how to do that?

Ok. I’m gonna test the drives one last time on a driver reader that I bought from Amazon. From there I will ask you how to do the new config. I want to say I appreciate everything and everyone in this forum. It’s really great how you guys help us newbs

Yes I have tried that. I have 2 chassis and a lot of spare external hba and internal hba. so I have tried the disks across 2 chassis with the same problems on the same disks. more disks show up on my spare chassis so it has lead me to believe it is a backplane problem with the norco 4024 chassis.

Ok as it seems the drives are no longer good. I think my backplane might have fried them. In this case with loosing so many disks at once, Inc a parity. Is it just a start over scenario? (no i dont have a back up, This was mainly a media server with all replaceable content.)

can i safely plug them into my windows gaming pc? would i just check in the bios? sorry im fairly new, but do understand most concepts and instrucitons.

Ok as of today I have replaced all sas cables and have tried to use different power supplies. My problem has progressed. Since changing out all the wiring my chassis (norco 4224) isn’t recognizing a lot of disk. I have swapped hba to test that. have swapped sas expanders to check that have hooked the hba direct to each back plane to test. I even have a spare chassis (norco 4220) And still some drives don’t show up. let me know if I should post diagnostics. Tho I can’t start my array.

ok, should i try a repair of disk 8 and 10? i also have replacement drives on standby

I tried to do it from the GUI, tho before i had tried it from the command line. Let me know a command to try and i will give it a shot.

Diagnostics posted, the emulated disks are unmountable yes. tower-diagnostics-20210902-0751.zip

Phase 1 - find and verify superblock... bad primary superblock - bad CRC in superblock !!! attempting to find secondary superblock... ...Sorry, could not find valid secondary superblock Exiting now. Im still unable to xfs repair the 2 disks that have the red X on them. What steps should or can i take from here?

Still struggling with this, Replacing wires and SAS expanders and SAS card on monday. Is there anything i should post here to show you guys whats going on?? im fairly lost

I mean I would change the disk. Change the slot on my chassis. Now that I look closer it’s just indiscriminately throwing errors it seems. I have 2 molex lines coming from my 1300w power supply. I am thinking about getting some sata to molex to spread the power across another cord they are both used to power the fan wall and the 6 molex connections on the backplane. I will buy new splitters and test with those. I also bought new sas cables to test from hba to backplane.

Thank you for the guidance, Attached are the Diagnostics When the parity rebuild starts, disks 1, 2, 7,8,9, 13 start to throw millions of read errors. and Disk 8 has an unmountable file system tower-diagnostics-20210704-0620.zip

Ok so i did that, but it seemed to follow the slots in unraid, then one would get better, and others would fail. It seems i lost a few disks. I replaced them, but still having the same problems. @itimpi i have attached the latest logs. I lost 3-4 disks, my shares are unavail. Some of the drives were formated. I think i totally Effed myself please give any advice. or recomend i restart from the start? I would be sad to lose everything but nothing was irreplaceable. Just a big media collection. No backups except for music tower-syslog-20210704-0327.zip

Yes I have tried that. Seems to be same problem. I have even changed my sas expander. Changed some wires too. is it possible it’s a power problem. I have 16 drives on one molex line.

Hello Everyone. I ran into a problem today when i accidentally took out a drive from my array while it was still running. I quickly put it back *hotswap* and then shut down the server and did a reboot. When rebooting it gave me disk errors on a few disks and i could not start the array. I refreshed the config to be able to start the array and get some info. It seems that 3 disks are having write errors. but only when the array starts. I have tried reseating my mini sas cables and believe it to be a problem with the HBA. But just to make sure i have attached my diagnostics. The drives giving me trouble are SDQ SDR & SDS They seem to show up and be able to work, but then they throw errors and show up as unassigned disks. If anyone has the time to look at this and can confirm my suspicions. Or tell me if im totally eff'd and should just buy new drives. or to be ready to kiss my media goodbye. Whatever the case i would really appreciate any knowledge on the subject and any guidance tower-diagnostics-20210622-1914.zip

@Alec.Dalessandro I seem to be having the same problem as of about 12 hours ago. Have a bunch cued stuff not connecting to peers. if anyone has a solution please let me know

here are the Diagnostics with the array running, in safe mode GUI tower-diagnostics-20191215-1342.zip
