I was alerted to my site, on a VPS, going down by Uptime monitor. I SSHd to it to reboot, which is usually what it needs, and then it all went bad.
Turns out the underlying NAS was rebooting for no apparent reason (according to my service provider) and I rebooted in the middle of that.
I have a dirty file system - but I can't run fsck fsck from util-linux 2.31.1
and I can't sudo sudo: unable to resolve host asimov: Resource temporarily unavailable
.
The web interface refuses to respond.
Apparently I have to reboot in recovery mode but all I have is the command line.
