http://bugzilla.opensuse.org/show_bug.cgi?id=1191347 Bug ID: 1191347 Summary: Yast2 Disk masks all systemd x.mount units Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.3 Hardware: All OS: openSUSE Leap 15.3 Status: NEW Severity: Major Priority: P5 - None Component: YaST2 Assignee: yast2-maintainers@suse.de Reporter: itteam@smartodds.co.uk QA Contact: jsrain@suse.com Found By: --- Blocker: --- Created attachment 852942 --> http://bugzilla.opensuse.org/attachment.cgi?id=852942&action=edit journal We've come across an issue whereby opening yast2 disk management causes all systemd x.mount units to be masked until reboot or manual intervention. On some systems this is causing issues restarting services which depend on these (eg nrpe with After=var-run.mount), which present an error: Failed to restart nrpe.service: Unit var.mount is masked. It's simple enough to trigger the masking with yast2 disk as follows. 1. Boot system, confirm var.mount for example is not masked: # systemctl status var.mount ��� var.mount - /var Loaded: loaded (/etc/fstab; generated) Active: active (mounted) since Tue 2021-10-05 17:17:26 BST; 1min 31s ago Where: /var What: /dev/mapper/vg_system-lv_var Docs: man:fstab(5) man:systemd-fstab-generator(8) Tasks: 0 (limit: 7030) CGroup: /system.slice/var.mount Oct 05 17:17:25 someserver1 systemd[1]: Mounting /var... Oct 05 17:17:26 someserver1 systemd[1]: Mounted /var. 2. Run yast2 disk
sudo yast2 disk
3. Accept the warning prompt and proceed to Abort or Finish without making any changes. 4. Check the status again of var.mount and find that it is masked (note the log of changed status, this was achieved setting journalctl to debug mode with systemctl log-level debug): # systemctl status var.mount ��� var.mount - /var Loaded: masked (Reason: Unit var.mount is masked.)

It's actually masking every mount unit it seems: # ll /run/systemd/system total 0 lrwxrwxrwx 1 root root 9 Oct 5 17:19 \x2esnapshots.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 backup.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 boot-grub2-i386\x2dpc.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 boot-grub2-x86_64\x2defi.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 data.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 dev-disk-by\x2did-dm\x2dname\x2dvg_system\x2dlv_swap.swap -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 dev-disk-by\x2did-dm\x2duuid\x2dLVM\x2dNn2wUiPvm30gKUVSZzdj7ZcrG3W8F0qgJkggHvpUF2wzkNeQpQmB1Vb4sk6o43zY.swap -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 dev-disk-by\x2duuid-61a850a3\x2de6cd\x2d4156\x2dbdfe\x2d59c040afdf8d.swap -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 dev-dm\x2d0.swap -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 dev-mapper-vg_system\x2dlv_swap.swap -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 dev-vg_system-lv_swap.swap -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 home.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 opt.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 root.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 srv.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 tmp.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 usr-local.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 var-lock.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 var-run.mount -> /dev/null lrwxrwxrwx 1 root root 9 Oct 5 17:19 var.mount -> /dev/null 6. At this point the service cannot be restarted: # systemctl restart nrpe Failed to restart nrpe.service: Unit var.mount is masked. Either rebooting, or removing the symlink and doing a daemon reload is sufficient to resolve individual units, in this case nrpe also needs tmp.mount (possibly due to the PrivateTmp=true directive): # rm /run/systemd/system/var.mount # systemctl daemon-reload # systemctl restart nrpe Failed to restart nrpe.service: Unit tmp.mount is masked. # rm /run/systemd/system/tmp.mount # systemctl daemon-reload # systemctl restart nrpe (starts fine) This latter behaviour though is where there is a divergence, the service will only fail to restart on *some* systems, despite the unit file (/usr/lib/systemd/system/nrpe.service) being identical and all systems seeing the same masking behaviour triggered by yast. So a few questions are raised, namely why is yast2 disk masking the x.mount units, is this expected, and is it supposed to leave them in this state? But then also why is it only having a tangible effect on some systems? Attached is the systemd journal (debug level). -- You are receiving this mail because: You are on the CC list for the bug.
