# CT Deletion with Stale RBD Config — 2026-07-14
|
|
|
|
## Problem
|
|
|
|
`pct destroy <CTID> --purge` fails with exit 255 when the RBD disk image
|
|
was already deleted by a prior operation:
|
|
|
|
```
|
|
rbd error: rbd: error opening image vm-112-disk-0: (2) No such file or directory
|
|
```
|
|
|
|
The CT config file remains in pmxcfs (`/etc/pve/lxc/NNN.conf`), so
|
|
`pct list` still shows the CT as `stopped`.
|
|
|
|
## Fix
|
|
|
|
```bash
|
|
# On the PVE node hosting the CT:
|
|
rm -f /etc/pve/lxc/NNN.conf
|
|
# Verify:
|
|
pct list | grep NNN # Should return nothing
|
|
```
|
|
|
|
## Reliable CT Deletion Sequence
|
|
|
|
1. `pct stop NNN` (ensure stopped)
|
|
2. `pct destroy NNN --purge --destroy-unreferenced-disks`
|
|
3. If it fails with RBD error but config remains:
|
|
`rm -f /etc/pve/lxc/NNN.conf`
|
|
4. Verify: `pct list | grep NNN` → empty
|
|
|
|
## Pitfall
|
|
|
|
`--destroy-unreferenced-disks` helps clean up orphaned RBD images not
|
|
referenced in the CT config, but if the RBD image is already gone, the
|
|
flag doesn't suppress the error — it just tries and fails on the missing
|
|
image. The config file is the leftover that needs manual cleanup.
|
|
|
|
## Session Context
|
|
|
|
CT112 (Authelia) was stopped and then deleted with `pct destroy 112
|
|
--purge`. The RBD image was apparently already removed (possibly during
|
|
a prior storage migration or manual cleanup), so the destroy command
|
|
failed on the missing image. The config was manually removed with
|
|
`rm -f /etc/pve/lxc/112.conf`.
