Observation

I hit

Failure (error.something).

when calling snapper -v cleanup number today in a system that has a broken filesystem which I only realized after the above command failed. The filesystem turned read-only and I assume snapper wants to write to some file and hence yields the error.

A bit similar to #246

Called with strace:

# strace -yy -f snapper -v cleanup number

Please provide the strace of snapperd instead of snapper. And also /var/log/snapper.log.

Sorry, the affected machine is a production machine that we fixed in the meantime. It should be possible to reproduce with a system where the complete root filesystem is forcefully turned r/o.

Well, I cannot reproduce it:

# snapper -v cleanup number
Deleting snapshot from root:
9
Deleting snapshot failed.

In the log I see:

delete snapshot failed, ioctl(BTRFS_IOC_SNAP_DESTROY) failed, errno:30 (Read-only file system)
