No files share, but still on the disk and I can access them

[djonesax]

Hi,

 

I just noticed that in my movies share there are no files in the share but the files appear to be on the disk and I can access them.  All the disks show active and healthy.  I wouldn't call my self an unraid superuser so I am looking for some pointers on where to start troubleshooting. I set this up years ago and its been a bit of set it and forget it aside from the occasional failed disk or USB stick death.  I have done some googleing but nothing that stands out as a solution.

 

Ideas?

You should provide your system diagnostics zip file (obtained via Tools >> Diagnostics) to get any sort of informed feedback.

Thanks, I added it to the original post.  Anything else helpful I can add?

It looks as if your cache disk has dropped offline.    Whether it has failed or not is not clear.

 

your best bet is to power-cycle the system to see if the cache drive comes back online.    After bringing the system back up post new diagnostics so we can see if the cache drive is now showing up, and if so what state it is in.

You have a share   'm-----k'  and another share 'M----s'.  The second share is exported and the first share is not.  I would suspect that is the problem.

 

Now, one more thing.  From what I see, these two shares have different names with one ending in 's' and the other in 'k'.  However, one share begins with a capital letter and the other with a small letter.  Let mean explain one thing.  With Linux, I can have a folder/directory named    movies    and a second one named     Movies   and everything would be fine.  I could look at them both with a Linux system because Linux recognizes that a capital letter is a different character than a small letter.  Windows does NOT make that distinction and you will only see one of the folders.   

 

EDIT:  When you post up that new diagnostics, please put in a new post.  That way thing make sense to the readers of this thread.

So I found that I dont have access to the mount but the permissions look the same as the other folders.

Its the one ending in "s"  The other is "mackbook" and its exported with AFP for timemachine backups.

[Frank1940]

It appears that your  Movies   share is using the cache drive.  If that drive (and it appears it is) is down, that is where I would suspect the issue lays.  You could turn off the Use Cache Drive setting in the share and see if that fixes this 'missing files' problem.   But you should still address that issue. 

 

Edit fixed typing errors...

I am with you, i was just looking at that.  Something has gone awry on that folder for sure.

 

root@Tower:~# ls -lath /mnt/cache/Movies/
/bin/ls: cannot access '/mnt/cache/Movies/HighResMovies': Permission denied
total 0
drwxrwx--- 9 nobody users 200 Jan  6  2018 ../
drwxrwx--- 3 nobody users  80 Oct 11  2014 ./
?????????? ? ?      ?       ?            ? HighResMovies

root@Tower:~# chown nobody /mnt/cache/Movies/HighResMovies
chown: cannot access '/mnt/cache/Movies/HighResMovies': Permission denied

 

[djonesax]

I turned the cache disk off for that share but I still get access denied.

[itimpi]

You also need to get the cache drive online as the system will be trying to access it to check if there are any files for that share on the cache (regardless of the Use Cache setting)..

[djonesax]

The cahe drive is online, and it being used right now for a separate file transfer to a different folder.  The folder permissions seem to be screwed up for the "HighResMovies" folder in the "Movies" folder but I get access denied when I try to fix it with cmod and chown.

 

root@Tower:~# ls -lath /mnt/cache/Movies/
/bin/ls: cannot access '/mnt/cache/Movies/HighResMovies': Permission denied

I get this when i check the filesystem on the cache disk

 

 

reiserfsck 3.6.27

Will read-only check consistency of the filesystem on /dev/sdb1
Will put log info to 'stdout'

The problem has occurred looks like a hardware problem. If you have
bad blocks, we advise you to get a new hard drive, because once you
get one bad block  that the disk  drive internals  cannot hide from
your sight,the chances of getting more are generally said to become
much higher  (precise statistics are unknown to us), and  this disk
drive is probably not expensive enough  for you to you to risk your
time and  data on it.  If you don't want to follow that follow that
advice then  if you have just a few bad blocks,  try writing to the
bad blocks  and see if the drive remaps  the bad blocks (that means
it takes a block  it has  in reserve  and allocates  it for use for
of that block number).  If it cannot remap the block,  use badblock
option (-B) with  reiserfs utils to handle this block correctly.

bread: Cannot read the block (2): (Input/output error).

So I removed the cache disk from the share, stopped and started the array and now I have my movies in the user share.

[Frank1940]

Looks like you need to be looking for a new cache drive.  I would definitely be looking at an ssd this time...

 

[djonesax]

The bad thing is now the cache drive not mountable and Ive been copying stuff off an old lap top all day and deleting old files. I might have gotten lucky because it looks like those other shares dont have the cashe drive enabled.

I have 500GB SSD sitting on my desk for this very purpose.

[Frank1940]

After you get this straighten out, you should be looking to upgrade Unraid to a much later version.

[djonesax]

for sure....  Any ideas on a free windows 10 or OSX reiserfs app to that i can use with an external hard drive enclosure to at least see what was on the cache drive?

[Frank1940]

You might be better off looking at the Unassigned Devices plugin...

This usual indicates bad sectors on the device, you can clone it with ddrescue then fix the filesystem.

[djonesax]

Got the cache disk installed and upgraded to the latest version.   That old disk must have an un-parked head because I can hear it moving around inside.
