Bug ID: 522308
Summary: 'Scanning devices' tries to mount all automounted CIFS
shares, twice per local disk
Classification: Applications
Product: partitionmanager
Version First 26.04.2
Reported In:
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
DESCRIPTION
I am using systemd automounting for a few SMB shares to my NAS:
//vault.seri/retro /mnt/retro cifs
noauto,x-systemd.automount,noserverino,file_mode=0777,dir_mode=0777,noperm,_netdev,forceuid,forcegid,uid=seri,gid=seri,credentials=/home/seri/.smbcredentials
0 0
(similar entries for the other shares)
The NAS is currently offline, so those mounts fail after a 5 second timeout.
This, however, makes KDE Partition Manager almost impossible to open, as it
seems to go through the entire list of defined shares and tries to mount each
of them during the 'scanning devices' process.
In total, it seems to try to mount each share twice, *twice per disk being
scanned*. In my case that's 7 shares * 2 tries * 2 times * 3 local disks = 84
mount attempts, equalling to a 'scanning devices' time of about 7 minutes.
STEPS TO REPRODUCE
1. Add a cifs automount share to the fstab, pointing to an address that cannot
be resolved, letting it run into a timeout
2. Reboot, then keep `sudo dmesg -w` open
3. Open KDE Partition manager
OBSERVED RESULT
(I already reduced the timeout to 500ms here to make it bearable to open)

...
EXPECTED RESULT
Should KDE Partition Manager cause CIFS shares to be mounted at all? If so:
1. Don't retry 4 times per local disk
2. Ideally make that visible in the 'scanning devices' UI
A "cancel" button would also be nice :)
