systemctl help local-fs.target
systemctl cat local-fs.target
I hope, it gives an answer to my question. For more details see
loginctl(1). Actually I was shooting in dark.
I didn't understand much from this, frankly speaking. But...
In your logs I see
> Stopped target local-fs-pre.target - Preparation for Local File Systems.
but no line for local-fs.target despite some entries related to user
processes.
There is
Apr 01 14:19:23 deb systemd[1]: Unmounting boot-efi.mount - /boot/efi...
Apr 01 14:19:23 deb systemd[1]: Stopped target local-fs.target - Local File Systems.
Apr 01 14:19:23 deb systemd[1]: Stopped systemd-tmpfiles-setup.service - Create System Files and Directories.
And it happens AFTER
APR 01 14:19:20 DEB SYSTEMD[1]: FAILED UNMOUNTING MNT-8CD66B97\X2DBDE6\X2D4475\X2DB875\X2D8F3928A8B14D.MOUNT - /MNT/8CD66B97-BDE6-4475-B875-8F3928A8B14D.
So, this means that IN FACT partitions were UNMOUNTED?
And i want to ask again: can these problems lead to information loss?
Yesterday once again reboot was stuck on FAILED UNMOUNTING... but after a minute it proceeded. So i guess it was waiting for umnounting to complete?
