Share showing wrong content when mounted via NFS

[Grobalt]

I posted this in the german board, but i have to ask here after a few days:

in short - i created a share, mounted this share from another computer (or for test reason via nfs local) and it shows the content of another share. I did this with 2 shares and it was reproducable -> showing the content of 2 old shares. totally crazy and i have no clue.

 

The new shares are "ron" and "scraping" -> ron is showing the content of "aufnahmen" and scraping is showing the content of "download"

Post your diagnostics zip file.

I am not an expert on this, but should the exports not have a unique value for the -fsid option for each share?   The ones that you are saying are going wrong are where they have the same fsid value as another entry.

where can i see this and how to change ? in the gui for share i dont see any fsid to set

You can't control the fsid.  Unraid takes care of it for you.  Have you tried a reboot?  Post the /etc/exports file content after a reboot.

 

You may have run into a bug.  I'll do some testing and see if there is a problem.

root@unraid:/etc# cat exports
# See exports(5) for a description.
# This file contains a list of all directories exported to other computers.
# It is used by rpc.nfsd and rpc.mountd.

"/mnt/user/aufnahmen" -fsid=100,async,no_subtree_check
"/mnt/user/download" -fsid=101,async,no_subtree_check
"/mnt/user/filme" -fsid=102,async,no_subtree_check *(ro,sec=sys,insecure,anongid                                                                                                                    =100,anonuid=99,all_squash)
"/mnt/user/ron" -fsid=102,async,no_subtree_check *(ro,sec=sys,insecure,anongid=1                                                                                                                    00,anonuid=99,all_squash)
"/mnt/user/serien" -fsid=103,async,no_subtree_check *(ro,sec=sys,insecure,anongi                                                                                                                    d=100,anonuid=99,all_squash)

reboot did not help, still duplicate fsid

Edit the the duplicated share "ron" /flash/config.shares/ folder and change the duplicate to the next in the sequence for fsids.  i.e. change ron to fsid 104.

 

I don't know how you got duplicates.  Can you take your flash drive to a PC and check the file system in case you have a flash issue?

 

Edit: You'll have to reboot or stop and restart the array.

[Grobalt]

I did edit before reboot to 104, but after reboot it was the old fsid. Let me do again to validate after some hours of sleep thank you

[dlandon]

Try changing the filme share.

[Grobalt]

i edited /boot/config/shares/ron.cfg to fsid 104 and restarted the array - seem to work. 

 

but then i created another new share, just for test purpose, enabled nfs export -> id received again a duplicate, already used fsid !

[dlandon]

I would turn off export on each of your shares and then turn them on one at a time and see if the fsid duplicates again as you re-assign them.

[Grobalt]

now it messed up the system rights ... 

shares with the same name as an old share have the old fsid when recreated -> duplicate

so i used new names, but the new shares are not listed under users, i cannot set the rights for them

[dlandon]

Can you show a screen shot?

[Grobalt]

sure, thanks !
