Hi All,
There's this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1708315
Would have been better if I discovered it during Alpha or Beta, but unfortunately I didn't. Now we have the situation that any bcache user upgrading to Fedora30 involuntarily currupts his storage.
This is huge! Accidentaly, after upgrade to F30 I experience two or three I/O hangs with bcache, so I temporarily detached cache device and (knock on wood) there are no problems (my rootfs is btrfs raid10 over bcache devices).
I suggest: 1) getting this bug into F30 Common Bugs page, with hint that detaching cache device before upgrade could help. 2) complement rhbz#1708315 with pointers to upstream report.
