possible missing data

[effectimminent2313]

i have a virtualized truenas setup with a tiny pool meant for testing various thing and against the rules someone may have put files on it instead of the main server and i need help getting those files back however truenas reports that there is space used but no files seem to exist

 

[Ericloewe]

How did you determine that no files exist?

 

[effectimminent2313]

i ran

Code:

ls -a

inside the pool directory

How did you determine that no files exist?

What's the output of zfs list -o space,mountpoint and where in the filesystem tree are you looking?

 

[effectimminent2313]

heres the output

Code:

root@truenas[~]#
root@truenas[~]# zfs list -o space,mountpoint

Pool w seems to be completely empty, apart from the system dataset. It's not impossible that someone threw some files in there, but those are pretty normal sizes...

 

[effectimminent2313]

so the 9.14M under used in w is just filesystem crud and whatnot? if so great

 

[Ericloewe]

Well, sort of. Logs, configuration databases, semi-disposable databases used for Samba, etc.

 

[effectimminent2313]

got ya, alright well i will get back to using the pool for testing thanks for all your help
