Proxmox web UI accessible but shell returns Error 500: close (rename) atomic file....

[raiz3n]

Hello everyone,


I’m running into an issue with my Proxmox server that started about 2 hours ago and I’m a bit stuck.
The web interface is still accessible, but any attempt to open a shell (node shell or VM shell) returns an HTTP 500 error.
There was an unexpected stop / interruption earlier. After that, the virtual machines did restart automatically and they all seem up and running.

It looks like pveproxy / pveshell is not responding correctly, but I can’t confirm since I don’t have shell access anymore.
I still have access to the system logs via the web UI, and I can copy/paste them below.

What I’ve checked so far:

• Web UI is reachable and responsive
• No recent intentional configuration changes
• Issue appeared suddenly

Proxmox version:
9.1.4
Error message (HTTP 500 / shell):
Error 500: close (rename) atomic file '/var/log/pve/tasks/active' failed: Permission denied)

Relevant logs (journal / syslog):

Feb 09 12:11:42 proxmox systemd-logind[1377]: System is powering down.

At this point, I’m wondering if a full reboot of the Proxmox host would be recommended — but I’m honestly a bit worried that the server might not come back up at all, given the current state.
Has anyone experienced something similar, or has advice on whether a reboot is safe or if there are checks I should do first?

Any help would be greatly appreciated. Thanks!

Hi,

Are you logged in as the root user? Have you tried a different browser?

 

[raiz3n]

Yes i'm logged as root user.
and i tried with different browser, same thing.
I see that corosync service is with "dead" status
pvefw-logger => failed
systemd-journald => failed
all others services are running

 

[Moayad]

Could you please post the output of the following commands:

mount
df -h /

Seems like you're not the only one. No solution so far, unfortunately. https://forum.proxmox.com/threads/c...tasks-active-failed-permission-denied.180139/

 

[raiz3n]

seriously? no solution ?
i tried also those commands, seen on other thread
chmod 777 on the file
and then
Bash:
systemctl stop pve-cluster
rm -f /var/log/pve/tasks/active*
rm -f /var/log/pve/tasks/index*
systemctl start pve-cluster[/CODE]

nothing..
file active doesn't exist anymore, but still the error 500, impossible to rename
nobody has another idea?
