Hi!
I have a snapshot with the read only flag set and I'm currently unable
to delete it or change the ro setting
btrfs property set -ts /path/t/snapshot ro false
ERROR: failed to set flags for /path/t/snapshot: Operation not permitted
Deleting the snapshot is also a no-go:
btrfs subvolume delete /path/t/snapshot
Delete subvolume (no-commit): '/path/t/snapshot'
ERROR: cannot delete '/path/t/snapshot': Operation not permitted
The snapshot information:
btrfs subvolume show /path/t/snapshot
/path/t/snapshot
Name: snapshot
UUID: 66a145da-a20d-a44e-bb7a-3535da400f5d
Parent UUID: f1866638-f77f-e34e-880d-e2e3bec1c88b
Received UUID: 66a145da-a20d-a44e-bb7a-3535da400f5d
Creation time: 2019-07-31 12:00:30 +0200
Subvolume ID: 23786
Generation: 1856068
Gen at creation: 1840490
Parent ID: 517
Top level ID: 517
Flags: readonly
Snapshot(s):
Any idea of what can I do?
Regards!

First question: are you running those commands as root?
Second question: has the FS itself gone read-only for some reason?
(e.g. corruption detected).

Hi! Thanks for the reply!
First: I am (g)root,, yes :)
Second: The snapshot was taken in ro mode, the fs is not ro and the
rest of the snapshots and volumes work as intended (rw)
Thanks

Maybe strace the failing command, and see if that provides a hint
what's going on?
