That is a terrifyingly massive bug and destroys the ability to run any production stuff on a host with even just a single container, as it could crash the whole host. (Trying to get CUPS working on the host, had to aa-complain it, even though I added abi <abi/3.0>, to the top and restarted cups)

Now to figure out how to get that space reclaimed on the backup server that I zfs send to... (without needing a full re-transfer)..

Yeah that did it. (On a test box I made a copy of the zvol to not mess with production. Will fix on production shortly.) Spose have to be careful to ensure discard is on (and wonder why it's not a default on..).

I guess a secondary question is can I turn on discard now (and reboot the VM) and then run e2defrag for eg?

Looked around for an answer to this but didnt quite find (except fstrim). I'm thinking that a VM's ext4fs ate a lot of disk, files subsequently deleted and the zvol remains large, despite being thin provisioned. I didnt have discard on because of oversight. Id like to get the space back...

AFAIR Apache and MariaDB also need nesting these days...

the weird fuse mount of /etc/pve causes issues. i ran out of disk on / now its unmodifyable for eg. I think I need to reboot :(

And where do these templates get downloaded from? Ie url on the internet to retrieve manually for eg. [SOLVED]: https://images.linuxcontainers.org/images/

Yes I use screen all the time, and I have one on the host, with one window per container. I wanted to save that one screen window login cuz I was already maxed at 50 screen windows. Yes, easy to escape the ssh, I want to escape the PCT ENTER itself, not the ssh.

Im ssh'd in to the host, course I can ssh in again and kill the session, was just wondering if there's a cleaner escape sequence. Seems there is supposed to be, but it does not seem to work.

Can't exit from a wedged container. It's frozen, dead, etc. I want to escape the PCT enter and diagnose from the host without having to open a new shell etc. Should be possible regardless of workarounds.

long time user but somehow stuck on a noob problem - how to escape PCT enter? had a container wedge, wanted my shell back on the host. this does NOT seem to be in play (no, Im not using it in screen with meta=^a) from pct(1): --escape \^?[a-z] (default = ^a) Escape sequence prefix. For...

D Dont need to reboot if you do the echo stuff as above. But echo wont survive a reboot, so have to update-initramfs to make permanent with the changes to /etc/modprobe.d/zfs.conf

Same error, different problem: somehow the host's /dev/pts got remounted ro, only when starting a CT did it popup til later I tried creating a new screen window 'read-only filesystem'. Chased it down to /dev/pts being ro, did a mount -o remount etc. So there are many causes to this error...

Had same issue, did a systemctl restart pve-cluster and it cleared up.
