CIFS automount using systemd getting read only

Hi, I have been trying to use FSTAB over the years to connect to windows shares successfully but I could not fix an issue about system waiting for umount at shutdown or reboot. So looked into the alternative option of systemd. I followed the wiki but have two issues, failed to mount at boot and if I manually mount it by starting it, it shows success but I am only getting read only.

I am using a credentials file with username and password that is the same I used when using fstab.

my systemd file is named and located at and my file contains the following

       /etc/systemd/system/home-au009900-my_data.mount                

[Unit]
Description=Mount Share at boot
Requires=NetworkManager.service
After=network-online.target
Wants=network-online.target

[Mount]
What=//192.168.0.100/my_data
Where=/home/au009900/my_data
Options=credentials=/home/au009900/credentials,vers=2.0,users,iochars$
Type=cifs
TimeoutSec=30

[Install]
WantedBy=multi-user.target

If I check the status I see

● home-au009900-my_data.mount - Mount Share at boot

When I browse the share I am only getting read access.

Re: CIFS automount using systemd getting read only

Hi, already tried with rw mount option?

Options=credentials=/home/au009900/credentials,vers=2.0,users,rw,iochars$

Re: CIFS automount using systemd getting read only

Hi  sorry yes the line was truncated in the original post, here is is in full

 Options=credentials=/home/au009900/credentials,vers=2.0,users,iocharset=utf8,rw,x-systemd.automount

basically did not change much except added the SMB version, as it was missing at first. Adding it did not make any difference.

Re: CIFS automount using systemd getting read only

Maybe the directory permissions aren't properly applied, who owns the files on the share? What if you explicitly pass the UID/GID of the user supposed to have access?

Re: CIFS automount using systemd getting read only

Hi, I am using the credentials of the admin account on the windows share.

If I remove the credentials option and instead hard code the username and password I get the same read only mount for the user.
But if I elevate my privalages to SU and browse the mounted share, I can read and write.

I had thought that mapping the mount point in my home profile and using the option "users" then allow any account to access the share with the correct rights.

[Unit]
Description=Mount Share at boot
Requires=NetworkManager.service
After=network-online.target
Wants=network-online.target

[Mount]
What=//192.168.0.100/my_data
Where=/home/au009900/my_data
Options=username=admin,password=thepassword,user,vers=2.0,iocharset=utf8,rw,x-systemd.automount
Type=cifs
TimeoutSec=30

[Install]
WantedBy=multi-user.target

I will now put the credentials file back in.

Re: CIFS automount using systemd getting read only

as a test I disabled the systemd

sudo systemctl disable home-au009900-my_data.mount

then edited my fstab folder to include the line

//192.168.0.100/my_data /home/au009900/my_data cifs credentials=/home/au009900/credentials,user,vers=2.0        0    0

rebooted, logged in user and opened file manager and opened the drive, with read and write, so it works with fstab, but I want to try and get systemd to work as I have read this is now a better option especially I have problems restarting my PC with fstab and it not succesfully unmounting and having to wait 1.5 minutes. Sounds minor but annoys me alot.

I then commented out the fstab line to prevent it from running, rebooted.
So reading the man pages it states that it defaults to DirectoryOption=0755, so I edited the .mount to now be

[Unit]
Description=Mount Share at boot
Requires=NetworkManager.service
After=network-online.target
Wants=network-online.target

[Mount]
What=//192.168.0.100/my_data
Where=/home/au009900/my_data
Options=credentials=/home/au009900/credentials,vers=2.0,iocharset=utf8,rw,x-systemd.automount
DirectoryMode=0770
Type=cifs
TimeoutSec=30

[Install]
WantedBy=multi-user.target

Alas still read only see mount output this after a reboot.

//192.168.0.100/my_data on /home/au009900/my_data type cifs (rw,relatime,vers=2.0,cache=strict,username=admin,domain=,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.0.100,

and systemctl status

Re: CIFS automount using systemd getting read only

I am not talking about your credentials, pass UID=au009900 ,GID=au009900 (or users or whatever the default group for your user is) additionally to your mount options. The systemd service instance runs as root, and without explicitly passing the UID and GID you wish to control the mountpoint with, it will default to using root, which your normal user has no write access to. Option "users" only allows your normal user to pass the share to a normal mount call,, however since you are mounting the share as root, the permissions are set for that.

Re: CIFS automount using systemd getting read only

OK great advice.
so added the uid and gid for my id and it works I have read and write access.

But problem still outstanding is its not connecting at restart. I have to run systemctl start from command line. after I log in, I suspect its due to no network even though I have enabled NetworkManager-wait-online. (or should I be using systemd.network-wait-online)

here is the journal

Re: CIFS automount using systemd getting read only

I did disable NetworkManager-wait-online and enabled systemd-networkd-wait-online and it seemed to delay the timing of connection in the journal till after I logged in but I think its just before its fully connected, see below journal
