Been working on standing up a new VM, and noticed after a restart the "domain" folder was empty where i was keeping the Vm image. I thought maybe i was crazy and saved it elsewhere so i set it up again. After a few hours I noticed some bad performance issues on the server (Not the VM). So i took a look at the active log, and saw some mcelog: Fallback Socket Memory error and mcelog: running trigger "socket-memory-error-trigger" (I have screen shots of that). 

 

So i thought maybe i was having some memory issues... so i tried to run memtest, but was unable to get it to boot from any USB drive i have... 

 

So just booted back into Unraid and noticed my unraid name reverted back to "TOWER" as well as the files again missing from the "Domains" share.  

 

I then noticed my cache pool of two SSDs were offline, and tried to  mount them with "fail" error. I was however able to brows them and it looks like the "domains" files are there... 

 

I shut the system down and took a look inside and tried to "re-seat" them with no luck... They are on their own power rail then the rest of the drives... so maybe that rail is bad... I can put a voltmeter on it.. but wanted to come here and ask some next steps before i mess anything up. Also for waterer reason i changed the name back to FS03...

 

I've uploaded the log files. 

 

-Thanks!

What filesystem is the pool, if it was a pool, with v6.11, it must be btrfs, but nothing is being found.

Followed a space invader tutorial years ago, but yea i think it was btrfs and yes a pool of two drives. I can brows it on the drives if i try. 

Then it should appear in that output, mount the pool and send the output of:

 

btrfs fi usage -T /mnt/disks/UD_name

 

When you say "mount the pool" are you saying just clicking "Mount" on both of those drives? If so I get an error mounting, below: 

 

 

Here are the results to "btrfs fi usage -T /mnt/disks/UD_name"

"ERROR: cannot access '/mnt/disks/UD_name': No such file or directory"

 

Thanks for taking the time to help me with this! 

 

Didn't you say the pool was mounting?

How did you browse it?

Sorry I may have misunderstood what i was doing. 

After manually mounting them by clicking the "Browse Disk Share". Is how to though i was looking at the contents. 

 

 

EDIT: If i browse the share normally the "Domains" folder is empty. However if i do it in the way i mentioned above the two ISOs are in there.

I'm still not sure what you mean, you cannot browse an unmounted device.

I click mount for the two drives. It gives me the error above (FAIL). 

But it shows this

 

and i click the GS01104.....(Link in blue) and browse a file structure. I assumed that what i was browsing was the contents on the pool... but you're leading me to believe that's not the case. 

OK, so there's an error but it mounts, by UD_name I meant the UD device name, post the output of:

 

 

 

btrfs fi usage -T /mnt/disks/130863404374"

 

Sure thing. I did the command for both drives:

Just needed one, both will show the same, still not sure why the pool doesn't show up under the other output, but do this:

 

-unmount the pool from UD

-create a new pool in Unraid

-set slots to two

-assign both devices to the pool

-start the array

 

Existing pool should import, but if it doesn't post new diags.

I did as you said. It it seems to work... in that if i browse the share via network i see the files again.. however it's saying I have two.. but one is encrypted... That was never the case... 

 

I've also posted the diags.

fs03-syslog-20240722-1758.zip

They were not assigned to the same pool as instructed, lets try one more time.

 

-stop the array

-unassign both devices

-delete both pools from the GUI

-create a new pool in Unraid

-set slots to two

-assign both devices to the same pool

-start the array

My apologies. Just did that and it seems to have worked! 

 

I'm uploading the diags just in case. 

 

I'm assuming i would run a parity check now. 

 

Any reason why this may have happened as well as why the name converted back? 

Was i on the right track with possible some bad RAM with "socket-memory-error-trigger" error i got?

Should be OK, but that is just the syslog, post the complete diags.

Possibly some files went missing from the flash drive, that can happen sometimes if there's fs corruption.
