Where has my data and free space gone?

[t_ams1st]

Hi folks,

This is the fourth time I've reinstalled FreeNAS due to making mistakes with the permissions settings and somehow I've now managed to "lose" 3.4 TB of space. I have 4x3TB drives installed in raid5. I had or should have 3.9TB of free space and don't know what I've changed to make the other 3.4TB vanish. How do I find out which dataset actually contains my data?
Is it on Home or Shared?

I had it running fine a few days ago with Plex and added transmission. I tried to setup port forwarding and managed to lock myself out of FreeNAS altogether (changing the subnet mask I think).

I am loathe to ask such questions but I have searched the forum and google but am obviously not asking the right question as I'm getting nowhere and don't want to delete my "Shared" dataset if that's where my data is actually stored.

Any help would be greatly appreciated. I have a lot to learn regarding this OS.

Cheers

You haven't lost any space.

4x3TB drives in RAIDZ1 yields about 8TiB of total storage. You have used 7.2 TiB with 512GiB free. There's some overhead. But the numbers are correct. Disregard the first line - that's the raw amount of storage before parity.

Hi gpsguy,

I reloaded FreeNAS tonight because I had changed permissions and created an SMB share at which point I went from 3.9TB free space down to 500GB, so reloaded the OS to try and wipe whatever settings I have messed up. So somehow I've created a 500GB share and can't see the rest of the free space. I have around 3.4TB of data on the drives. But which dataset is it on?

In a shell enter zfs list and post the output in code brackets

All your data is located in "/mnt/Home/Shared", about 7.15TB. You must have copied a lot of data into that location. If you did not copy that much data there then you likely have snapshots enabled and did a little overkill in the configuration. If that is the case then you need to address it.

 

[SweetAndLow]

your dataset named "Shared" is using 7.15TB of space so I would assume all your data is in there.

 

[t_ams1st]

There should only be around 3.4TB & 3.9TB empty. I created a SMB share for the \mnt\home which shows in windows as Homes and I cannot connect to it! This is the second time this has happened, I thought I remembered something about windows remembering old share names and confusing them?

I need to see the files on \mnt\home to see why they are taking up so much space.

 

[joeschmuck]

You likely have a permission issue with respect to the SMB access.

This again.. no you did not, you have created a share to the dataset /mnt/home/shared

I’m guessing you have copied your data to both home and shared in your trials.. if it’s something that can be replicated then I would destroy the pool and look at monkeys video on smb permissions

 

[t_ams1st]

Data was only copied once, it took long enough. It was only when I changed permissions recursively that this occurred. I now get "windows 7 the network path was not found" when trying to connect from windows. I've messed up the volume settings as a clean install is not helping. I need to "see" the files so I can get them back off and start again.

 

[garm]

Reinstalling FreeNAS won’t do anything to your zpool, that would be insane. The pool can be destroyed without reinstalling, but there is no saying what you have done to FreeNAS. A fresh install would put you in a known state for following monkeys video

 

[t_ams1st]

This is a fresh install. I don't think i've destroyed anything, tied myself in knots maybe. Should /mnt/home be left as a unix share? I did change it to windows but have since changed back. I set a user & group with full access and attempted to map the drive in windows and get the "network path not found" as windows sees a share called "Homes" which doesn't exist. I had this earlier and a fresh install wiped the settings I had messed up but this time...

 

[joeschmuck]

If you want to see what is there, in the FreeNAS GUI open the Shell (in the left pane) and type cd /mnt/Home/Shared and then ls and you will see all the directory structure and files you moved there. If you are not familiar with the commands cd or ls then you should nto be messing around with FreeNAS and you need to do some research into how BSD command line commands work. Google search the two commands, "freebsd cd man" and "freebsd ls man" for the manual on these commands.

Hope this helps.

 

[t_ams1st]

Thanks Joe, I'll be home in a couple of hours to try again.

I'm familiar with similar DOS commands so understand what they do. It's the permissions and the demarcation between Freenas and windows that seems to be getting me. I'm going to reinstall when I get home and follow the video link above nice and slowly and hopefully that will get me back to at least being able to map the share in windows.

 

[t_ams1st]

Progress. I managed to get back in. I have somehow duplicated my data which is why my free space has plummeted but is this actually two copies or is one referring to the other?

On /mnt/Home I have all my folders + a Shared folder which contains all the folders on Home.

Yet when I run ls in both directories I get:

Code:

[root@freenas ~]# cd /mnt/Home																									 
[root@freenas /mnt/Home]# ls																										
.windows		Guest		   Shared																							 
[root@freenas /mnt/Home]# /mnt/Home/Shared																						 
bash: /mnt/Home/Shared: Is a directory																							 
[root@freenas /mnt/Home]# cd /mnt/Home/Shared																					   
[root@freenas /mnt/Home/Shared]# ls																								 
.ReadyDLNA							  film									Preferences.xml									 
.windows								Guest								   reaper-license.rk

BOOKS								   photo								   Tutorial											
Cache								   Plug-in Support						 USL1.xlsx										   
Codecs								  Plug-ins								Wendy											   
[root@freenas /mnt/Home/Shared]#

/mnt/Home only shows the Shared folder and not the rest of the folders I can see in windows explorer.

Which set of files is it safe to delete?

 

[SweetAndLow]

I don't see you duplicating you files? It looks like everything is in your shared dataset. Looks like you also have a directory named guest. Does it have a propose?

 

[t_ams1st]

Windows explorer shows all the folders that are also contained in the Shared folder but ls does not.

Guest is probably a relic from failed attempts earlier, I think.

 

[t_ams1st]

One set of files needs to go!

Screenshots of your window share settings? I don't understand what you have going on.
