Description

Since upgrading to 15.2.10 I sometimes receive the following error when attempting to remove a snapshot:

```
rbd: failed to remove snapshot: (1) Operation not permitted
```

However, when I check the volumes list with `rbd ls -l --pool` I see that the snapshot I tried to remove is in fact gone.

The above error interrupts my backup process though as it aborts on error. As it stands, I have to restart the backup multiple times each run.

Happy to provide further details, just not sure where to gather them from, or what logging should be enabled.

Still seeing this on an almost daily basis.

Today I was met with

rbd: failed to create snapshot: (1) Operation not permitted

However, retrying the operation (once the error was noticed) without any cluster configuration changes succeeded.

Hi Jamin,

This is puzzling since librbd doesn't generally fail with EPERM. If it still reproduces, please append "--debug-monc 30 --debug-auth 30 --debug-rbd 30 --debug-ms 1" to your "rbd snap rm" invocation and capture the output.
