If it were me, I'd include both. Maybe the image is incomplete or vice versa. The debug tree output is also human readable. I'd also put them up in a cloud location where you can kinda forget about them for a while, I've had images not looked at for 6+ months by a dev. > I think I will use the subject of this thread as summary to file the > bug. Can you think of something more suitable or is that fine? I would try to summarize something like: file system created with btrfs-progs version -----, and mostly used with kernel version -----, and inexplicably the file system became unusable at boot time always mounting only readonly. Newer kernel versions still could not mount it, nor was btrfs check using btrfs-progs version ----- able to repair. See thread URL for more details. btrfs-image URL btrfs-debug-tree URL > I think I will reinstall the OS since, even if I manage to recover the > file system from this issue, that OS will be something I can not trust > fully. Yeah pretty much that's right. There is an rpm command where you can have it check the signatures of all installed binaries, but I forget what it is offhand. That'd be an alternative to reinstalling if the init options were to work. -- Chris Murphy
