macOS Sierra autmount problems

This has nothing to do with Plex as such, but I suspect that quite a few in here might have the same configuration as I do

I have all my Plex content on my Synology. On the Mac Mini that hosts my PMP (because the Synology is not string enough to do transcodes for the whole family) I have the shares from the Synology auto mounted, because regular mounting would screw up if something happened to the connection between the two.

This setup has been running perfectly for a couple of years - since at least OSX Mavericks.I followed this guide back then

After updating to Sierra I had a lot of problems with Keychain, which forced me to delete that. Maybe this is the cause of my troubles, or maybe it’s Sierra it self.

Anyway - I have a /mnt/NAS folder where i have the following mounted.
/mnt/TV/
/mnt/Movies/Kids
/mnt/Movies/Movies

These are made recently, as I previously had the /mnt/Resources folders from the guide, and I thought maybe it would help with new folders (stupid - I know)

Basically, every 2 or 3 days or so, one of the folders under NAS will disappear from the Finder, and if I try to enter the folder through Terminal I get ‘Permission denied’. I then have to restart the machine to get in again. Maybe there’s another way but the $ sudo automount -vc command doesn’t work. listing looks like this

cbjerg-server:NAS cbjerg$ ls -la
total 70
dr-xr-xr-x  4 root    wheel      3 Nov 30 17:15 .
drwxr-xr-x  4 root    wheel    136 Nov 23 22:17 ..
drwx------@ 1 cbjerg  wheel  16384 Jul  3 11:11 Film
drwx------@ 1 cbjerg  wheel  16384 Nov 21 18:56 TV
cbjerg-server:NAS cbjerg$

Well - if anyone knows what to do, please give me a hint

Similar issue here - I am starting to think there is a SMB file system issue in Sierra. I have noticed that if I wait a while I am able to mount the shares again without rebooting.

What NAS are you using?

Are you mounting these as smb:// afp:// or cifs://?

I’m using smb. In my auto-resources file I have them mapped like this
TV -fstype=smbfs ://nas/TV

It’s a Synology DS1513+

I’m having the same issue…anyone have a guide to help walk me through this

fwiw I’ve now downloaded the AutoMounter app on App Store, as suggested on this topic

Not had a problem since, but it’s only been a couple of days

Beware it’s a 15$ app though - I just couldn’t be arsed anymore

I purchased AutoMounter from the OS X App Store, just to save hours of headache.

using NFS is more stable, works for me on latest OS MacSierra.
