hi,

did you try to reboot?
what's on container 741?

 

[mathx]

I fear rebooting the whole server as nothing may work afterwards if this problem is deep. Also I come from a culture of "reboot as last resort as you may not get access to the machine afterwards" (even with BMC/IPMI).

Nothing special but a deb9.8 container 741. Something is corrupt on this server, been having odd issues ever since though I have done nothing special to it ever. I will move all the containers off and reinstall it.

i'd also check for hardware issues to avoid future problems.

update: was finally able to move 741 off the server and pct destroy 741 it, and now I can pct list. However, I still dont trust the server due to repeated situations where I pct enter into a CT and get "proc not mounted" whereas ssh'ing in works ok. something bizarre is afoot. and now has started occuring on another PVE host.

 

[mathx]

This continues to happen on multiple 5.x hosts where /proc disappears to certain contexts (ie pct enter for eg, while SSH in works -- probably because SSH is inheriting a working context from the daemon whereas pct enter is a new context initliaization). Will report if it occurs in 6.x. Dont have enough experience yet with 6.x hosts/ct's.

Due to this problem, I am not trusting any upgrades from 5.x to 6.x, but doing full reinstalls. A lot more work.
