How to Stop udisks2.filesystem-mount-system from attempting to mount a "not required" partition

English Install/Boot/Login

I two SSDs on my PC, one dedicated to Windows and the other for Leap. The SSD for Leap has a number of partitions of which sda2 is for “/” for Leap 15.3 and sda3 for 15.4 and a common Swap partition. Each OS has its own Home partition plus two partitions for permanent data.

Let me first state that this problem was not there when I was having Leap 15.2 alongside 15.3 and has come up after I replaced 15.2 with a fresh install of 15.4. Starting 15.3 there is no issue. When I start 15.4 and log in I get a message that a program is trying to mount sdb2 for which it asks for root password. There is certainly no problem in selecting “cancel” and proceeding but why should it happen?

I have tried to see if it can be corrected through the Partioner, but could not find any way to do it. The “partitioner” also appears to have changed. Earlier if I remember correctly there was an option to see and change mount points of various partitions.

I do not remember selecting any options regarding mounting of additional partitions. Does the system try to mount all the Btrfs partitions at the start? Though the issue is not big one would like to stop the message popping up and the said partition not being automatically mounted.

One way is to include those filesystems in fstab using the noauto option. Adding other options can make mounting as desired and when desired simpler and easier than might be otherwise.

You could start with telling your desktop environment where you log in.

I use the following local udev rules:

**erlangen:~ #** cat /etc/udev/rules.d/99-udisks2.rules  
# UDISKS_FILESYSTEM_SHARED 
# ==1: mount filesystem to a shared directory (/media/VolumeName) 
# ==0: mount filesystem to a private directory (/run/media/$USER/VolumeName) 
# See udisks(8) 
ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{UDISKS_FILESYSTEM_SHARED}="1" 
SUBSYSTEM=="block", ENV{ID_FS_UUID}=="2260f160-cc05-47cc-9893-cc32c050177d", ENV{UDISKS_IGNORE}="1" 
**erlangen:~ #**

Udisks never tinkers with the ignored file system.

**erlangen:~ #** grep /HDD /etc/fstab 
UUID=2260f160-cc05-47cc-9893-cc32c050177d  **/HDD**                    btrfs  user,noauto                   0  0 
**erlangen:~ #**

Thanks. Managed to do it through System Settings -> Removable Storage -> Removable Devices by setting by appropriate selection under Automount Device not to automount at log in.
