Am I supposed to have a /user and /user0 directory

[danith]

I always thought it was weird to have both and finally decided to just check

If user and user0 are both valid, what is the purpose of them as they seem to have the same directories

It was really put into place for Mover

 

User contains all of your files in all of your shares

 

User0 contains all of your files in all of your shares EXCLUDING what is currently on the cache drive

Squid gave you a good answer but to expand a bit.

 

User shares in general aggragate folders from multiple disks.

 

For example, you have a share called Downloads (I am going to assume this isn't cache only even though it likely is...)

 

#What the user share downloads is located at 
/mnt/user/Downloads

#What this user share is actually doing is aggragating the following places into one view
/mnt/disk1/Downloads 
/mnt/disk2/Downloads 
... 
/mnt/diskX/Downloads  
#(Where X is the number of disks in your array that this user share is allowed to be on)
/mnt/cache/Downloads

 

 

This allows you to browse one folder and get a combined view, even though your data is actually in a lot of different folders on different disks.

 

Now for User0

 

#What the user share downloads is located at 
/mnt/user0/Downloads

#What this user share is actually doing is aggragating the following places into one view
/mnt/disk1/Downloads 
/mnt/disk2/Downloads 
... 
/mnt/diskX/Downloads  
#(Where X is the number of disks in your array that this user share is allowed to be on)
# Key difference is that user0 does not include /mnt/cache/Downloads

 

So when you look at the directories under /mnt/user/ and /mnt/user0 they should look exactly the same (maybe not if there are cache only shares... not sure.)

 

Why was explained by Squid already, it's used by the Mover script to help move files on the Cache to a disk in the array.

 

But you can also use user0 if you have a share that uses the cache drive but you want to bypass writing to the cache drive and write directly to the array for some reason. (Or at least I think you can do that, pretty sure it works that way)
