I've taken it out of the unraid box and its connected to my main linux machine to see if i could do anything here but all i get is "Error mounting /dev/sde1 at /media...: mount(2): system call failed: No such file or directory"

 

How to proceed? Is there anything that can be done?

 

While googling some things I saw another unraid post mention running the command "btrfs fi show /dev/sde1" which outputs the following, it still shows used space.

Label: none  uuid: 3346e7ab-0a8a-4c11-bb04-9ccbcdc4e414
	Total devices 1 FS bytes used 87.25GiB
	devid    1 size 232.89GiB used 126.02GiB path /dev/sde1

 

See below for some recovery options:

The 3rd command listed under the read-only section "ro,notreelog,nologreplay" worked and I'm copying as we speak.

 

It's unclear to me if this is a failing drive or something else happened and i'm safe to just reformat and put it back into service.

 

I grabbed diagnostics before shutting it down the first time, according to my emailed errors this happened at exactly 9AM my time.

Drive looks fine, could still be hardware related, like a RAM or similar issue, not bad idea to run at least one pass of memtest.

I reconnected the drive to the system and ran memtest which found no errors. Upon restarting into unraid the cache drive is randomly back. Should I trust this is ok?

 

Edit: I didn't trust it and attempted to rm the appdata folder because i had already restored that using a backup directly to the array and i didn't want things to get mixed. I'm hit with the following message on hundreds of files

 

rm: cannot remove 'appdata/jellyfin/dlna/system/Sony Bravia (2014).xml': Read-only file system
rm: cannot remove 'appdata/jellyfin/dlna/system/Sony PlayStation 3.xml': Read-only file system
rm: cannot remove 'appdata/jellyfin/dlna/system/Sony PlayStation 4.xml': Read-only file system
rm: cannot remove 'appdata/jellyfin/dlna/system/WDTV Live.xml': Read-only file system
rm: cannot remove 'appdata/jellyfin/dlna/system/Xbox One.xml': Read-only file system
rm: cannot remove 'appdata/jellyfin/dlna/user': Read-only file system

But other files on the system can be deleted without issue.

 

Edit 2: I'm now hunting for a way to somehow verify every bit of an ssd to see if it catches some kind of error? I'm not sure if thats possible.

No, you should re-format.
