So I have the following setup in Ubuntu 18.04:
/dev/md0: / (ext4) /dev/md1: swap /dev/md2: /var/lib (ext4)
I needed to free a couple of GB space after /dev/md2, so I decided to live boot using SystemRescueCD, and shrunk /dev/md2 with GParted which claimed to succeed (but the unassigned space after md2 didn't change nevertheless).
Anyway, I decided to reboot and now there is a partial boot process interrupted by several Load Kernel Modules failures wich finally drops onto Emergency Mode console:
[ OK ] Started Tell Plymouth To Write Out Runtime Data. [ OK ] Started Show Plymouth Boot Screen. [FAILED] Failed to start Load Kernel Modules. See 'systemctl status systemd-modules-load.service' for details. ... [ OK ] Started Avahi mDNS/DNS-SD Stack. [ OK ] Stopped Cgroup management daemon. [FAILED] Failed to start Cgroup management daemon. See 'systemctl status cgmanager.service' for details.
RAID1 arrays are detected and used with no problem apparently as per:
cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md2 : active raid1 sda5 sdb5 296717824 blocks super 1.2 [2/2] [UU] md1 : active raid1 sda3 sdb3 521856 blocks super 1.2 [2/2] [UU] md0 : active raid1 sda1 sdb1 15181184 blocks super 1.2 [2/2] [UU] unused devices: <none>
Also I can access all filesystems and browse through files and directories with no trouble AFAIK.
Also tried to :
update-initramfs -u update-grub
And also (just in case):
dpkg --reconfigure -a
With no errors at all to no avail, so I'm getting a bit lost here. Any suggestions should be welcome.
