[BUG] Automount fail on reboot with Ubuntu 20.04

[JOduMonT]

@nebulon said in Why my CIFS automatic mount fail on every reboot ?:

Do you see any failing attempt of automounting it during boot?

I did manually look the /var/log/dmesg and saw nothing anormal

@nebulon said in Why my CIFS automatic mount fail on every reboot ?:

Can you try adding defaults,_netdev to the fstab line? Maybe the network comes up a bit too slowly and thus the automount fails?

I did add those line, without success
I still need to do mount -a after a reboot

BTW it is on Ubuntu 20.04 LTS

[nebulon]

Hm the exact same options work for me fine, however on 18.04 so this indeed might have changed in behavior, although I can't really find anything related to that.

[p44]

@jodumont Me too I had this behavior on last restart...

[jdaviescoates]

It's working fine for me.

Here is what I have in fstab:

//uxxxxx.your-storagebox.de/backup /mnt/storage cifs iocharset=utf8,rw,credentials=/xxx/xxxxx-credentials.txt,uid=yellowtent,gid=yellowtent,file_mode=0660,dir_mode=0770 0 0

It did unmount once during a backup, but that's the only hiccup I've had to date.

@jdaviescoates are you with 18.04LTS or 20.04LTS ?

[jdaviescoates]

@jodumont 18.04. You?

@jdaviescoates How is working now? Did you experienced problems in last days? I switched to Wasabi meanwhile find a durable solution to this problem...

[jdaviescoates]

@p44 I'm not having any problems. Streaming music off of my Hetzner Storage Box mounted as a Cloudron Volume and connected to my Navidrome app as I type.

If I am reading those version messages correctly, it does look like the automount on Ubuntu 20 has some kind of regression, while servers on 18 are working reliably?

In plain english yes the issue seams to be only with Ubuntu 20.04

[jdaviescoates]

Possible related to this?

SMB1 disabled by default: can still be enabled via a /etc/samba/smb.conf config change;

thank for your reach, I'll definitely give a try to this and come back soon.

[JOduMonT]

@jdaviescoates I just look at it
and on Cloudron Samba server is not installed
so nothing to configure in /etc/samba/* which actually don't even exist.

WEBDAV

I have the same behavior with webdav
on reboot I have to login and do mount -a

here the option for my davfs in /etc/fstab: rw,_netdev,uid=yellowtent,gid=yellowtent,file_mode=0660,dir_mode=0770 0 0
I also tried with auto and defaults

few people suggest to use rc.local

[JOduMonT]

I just got an idea
@nebulon
it is possible than cloudron mount the volumes before my automount so then the target directory of my automount is not empty ?

Also how could I destroy thoses volumes the GUI don't make it happen ?

nope, even without any volumes configured in Cloudron
CIFS and WEBDAV won't mount automatically

[JOduMonT]

@nebulon and @girish

I just copy the config (/etc/fstab and /etc/davfs2/secret) to my Ubuntu 20.04LTS Desktop
and my webdav mount automatically on the reboot.

So it seams to be a bug on the cloudron side.

[nebulon]

Cloudron itself does not handle any mount points as such. So this looks like this is some issue with 20.04 server then. Note that the desktop flavor has a lot more things installed usually, which may or may not trigger automounting correctly.

I have no doubt of the quality of coding from the Cloudron Team
but I just boot an ubuntu 20.04 LTS at Hetzner
did

apt update
apt install -y davfs2
mkdir /mnt/storagebox

than cut and past my 2 lines
1 from /etc/fstab
1 for /etc/davfs2/secret

reboot and it work

so yes Ubuntu Desktop have probably more fuse than server but now the only difference is Cloudron.

[nebulon]

thanks for testing, so then probably one of the dependencies we install, somehow changes either the init order or even disables some bits there. Looks like we have to debug this further then on fresh installations to get some more information what systemd does differently in both scenarios.
