Hi, experts

 

All was working fine until I clicked share tab, and noticed the all my user shares are gone. While they were unseen, all the data are still properly stored on the disk (I can still see /mnt/user/ folder and all its sub folders). But the network devices couldn't find any user shares either previously exported from nfs or smb. 

 

This is really bugging all day long. Please help!! Thanks!

Try booting in safe mode.

Thanks for the timely response.

 

I tried. The problem remains. 

 

I attached the report collected from the safe-mode.

Do you think this is related to folder permission?

 

Not spotted anything obvious yet.   It might be worth running File System Checks on the cache pool and each individual array drive?

I am seeing some errors like

 

Jan 27 00:32:44 MWEI-NAS emhttpd: import flash device: sda Jan 27 00:32:45 MWEI-NAS emhttpd: Starting services... Jan 27 00:32:45 MWEI-NAS emhttpd: shcmd (10): /etc/rc.d/rc.samba stop Jan 27 00:32:45 MWEI-NAS nmbd[2428]: [2021/01/27 00:32:45.039804, 0] ../../source3/nmbd/nmbd.c:59(terminate) Jan 27 00:32:45 MWEI-NAS nmbd[2428]: Got SIGTERM: going down...

 

Related?

Ran the file system check, they all look good. Honestly, they are all new drives.

Just a thought - it is it only the Shares tab in the GUI that is mis-behaving?  For instance can you see the shares across the network.  If that is the case make sure that you have the Unraid server white-listed in any ad-blocker (or similar) you might have installed in the browser you are using.  Ad-blockers have been known to interfere with the Unraid GUI with the Shares tab one of the more frequent victims.

No, all user shares are gone from the network too. But they do exist in the /mnt/user/ folder. I felt like it is an exporting related issue. 

I must admit this does seen to be something unusual   Since you say that it also occur when booted into Safe Mode that rules out any plugin being the cause of your issue (which would have been the other obvious potential suspects).

 

Hopefully somebody will spot something in the Diagnostics or come up with another suggestion as to what could cause this.

folder permission

Those look OK but what about a level up from there, /mnt ?

No that's wrong. Don't know how it got that way. Have you tried rebooting?

@trurl

 

Do you know what are the expected setting?

 

Perhaps, I accidentally “chown” them. I tried umount the user and user0, and then “rm -rf” to see whether the system would regenerate them back. It looked like they were recreated, that is the default settings came up after starting the array.

 

Also been rebooted many times both in normal and safe mode, but no difference.

Appreciate your sharing. It looks like the user and group execute permission are missing from those folders on my server.

 

I don't recall me purposely updating them. I will give it a try to make up the grants like yours anyway. Stay tuned.

 

 

Bingo. Hats off to @trurl

 

I granted the gu exec permission.

 

The shares came back on right away. The permission is well preserved too even after I restarted the array.

 

Another two newbie questions:

 

😀 How do I mark this thread as solved? 

 

How do I give you some credits on helping me?

You can just edit your initial post and add (Solved) at the beginning of the title.

 

Excellent! Done marking the topic. 

 

Thanks everyone of the community! @ChatNoir  @trurl
