Do you have a backup of any system or data partitions? Can't see a tape backup device in "ioscan" but maybe you backup across the network?

Did the system crash or for that matter has it had a cold boot for any reason since the failure? Not recommending that you do actually reboot or run "fsck" (because your system may be precarious) but just wondering whether "fsck" has been run by the system already?

SYSTEMD-FSCK@.SERVICE(8)				       systemd-fsck@.service					  SYSTEMD-FSCK@.SERVICE(8)

NAME
systemd-fsck@.service, systemd-fsck-root.service, systemd-fsck - File system checker logic SYNOPSIS
systemd-fsck@.service systemd-fsck-root.service /usr/lib/systemd/systemd-fsck DESCRIPTION
systemd-fsck@.service is a service responsible for file system checks. It is instantiated for each device that requires a file system check. systemd-fsck-root.service is responsible for file system checks on the root file system. The root file system check is performed before the other file systems. Either service is enabled at boot if passno in /etc/fstab for the filesystem is set to a value greater than zero. systemd-fsck will forward file system checking progress to the console. If a file system check fails, emergency mode is activated, by isolating to emergency.target. KERNEL COMMAND LINE
systemd-fsck understands one kernel command line parameter: fsck.mode= One of "auto", "force", "skip". Controls the mode of operation. The default is "auto", and ensures that file system checks are done when the file system checker deems them necessary. "force" unconditionally results in full file system checks. "skip" skips any file system checks. SEE ALSO
