unraid wiki check disk filesystems

So  i followed your link, used the "[Plugin] Fix Common Problems".

The initial scan showed me this:

Then when is re-scanned this (the system file errror disappeared, is this because of maintenance mode?):

 

And the information i get when i start the array in "maintenance mode":

How did the file system type get set to BTRFS? It should be ReiserFS like your previous screenshot showed.

Yes

How did the file system type get set to BTRFS? It should be ReiserFS like your previous screenshot showed.

Because he was playing with the different FS types trying to get it to mount.  Probably left it at btrfs.

 

Should switch it to ReiserFS before running the FS checks (since OP is coming from V5 it's going to be Reiser)

Since the disk was used in V5, it should be ReiserFS. I'd try manually setting the file system type in the disk setting to Reiser and see if it mounts.

I tried it out(ReiserFS,see screenshots), It's says: "unmountable Disk"

After that i tried to mount it as the other two disk formats(xfs and the third one), same result:"unmountable Disk"

Squid is right, file format was still on BTRF, now i returned it ReiserFS and got this:

So what should be my next step?

Run the file system check previously linked

My result of  using file system check:

It seems my main problem is the missing superblock?!

It looked it up and found this instruction on:

https://lime-technology.com/wiki/index.php/Check_Disk_Filesystems#Checking_and_fixing_drives_in_the_webGui

 

Would you recommend these steps? or should i try the "reiserfsck --fix-fixable /dev/md3 -> fixes file system errors" first?

And can i use the "answers" from the example below for my drive(it is noticed that inaccurate answers could damage the system)?

Just follow the instructions exactly as reiserfsck gives them, assisted by that section from Check Disk File systems.  Without a ReiserFS superblock, you can't try any other options, as they won't even be able to start.  Once you have a valid ReiserFS superblock, you will be instructed to run it again with the --rebuild-tree option.  Just do whatever it says.

Tried it with this result:

Then i tried to rebuild the root tree with following result:

That means the disk has bad sectors, you can try using -B, but there will/could be some data loss.

No other way?  What does -B mean? For not running in background? I just know --rebuild-tree -S /Dev/md2

You basicalyy have 2 options:

 

Try to remap the bad sectors with HDD Regenerator (or similar) and then run reiserfsck again.

 

or

 

Run badblocks to generate a list of bad sectors on that disk, then run reiserfsck --rebuild-tree -B file.txt (using the previously generated file so reiserfsk knows how to handle those sectors)

 

 

If the disk is severely damaged with lots of bad sectors it may not work, with either option.

Is the Command "reiserfsck --rebuild-tree -B file.txt" or "reiserfsck --rebuild-tree -B /Dev/md2" (in my case disk2)?

It would be something like this:

 

reiserfsck --rebuild-tree -B /boot/badblocks.log /dev/md2

 

Obviously indicating the right path/name to the badblocks output.

It would be something like this:

 

reiserfsck --rebuild-tree -B /boot/badblocks.log /dev/md2

"reiserfsck --rebuild-tree -B /boot/badblocks.log /dev/md2" doesn't work(oh wonder) so i tried:

 

"reiserfsck --rebuild-tree -B /boot/stdout.log /dev/md2" doesn't work ether, tried it because it console said "...write log file into 'stdrou' "

 

What i'm doing wrong?

Did you run badblocks first?

Sorry, can't find/know the command for that?!
