No. Repair is completely independent from kernel version, so kernel doesn't have anything to do with it. > 2) The kernel at the time of fault originally occurring? I don't think the fault is caused by that v4.18 kernel, but a much older kernel. It's v4.18+ kernel that introduces such sanity check and exposed such old corruption. > > I am now running OpenSuse Tumbleweed to repair this: > # uname -a > Linux linux-h5nt 4.19.8-1-default #1 SMP PREEMPT Sun Dec 9 20:08:37 > UTC 2018 (9cae63f) x86_64 x86_64 x86_64 GNU/Linux > > I have run the https://github.com/adam900710/btrfs-progs/tree/check-next > with latest commit of 13th Nov 2018. > When I run make, it fails. > Could you please advise if I am missing something? > > Below are the make errors.

You may need but not limited development headers of: libuuid, libacl, libblkid, lzo, zlib, zstd, e2fsprogs. (Name may var for different distros, either with lib prefix or without) And you may need to disable documentation by using "./configure --disable-documentation" Thanks, Qu > > On Sun, Dec 23, 2018 at 8:51 AM Qu Wenruo <quwenruo.btrfs@xxxxxxx> wrote: >> >> >> >> On 2018/12/23 上午2:12, Jesse Emeth wrote: >>> BTRFS /@/ with home as subvolume results in Firefox cache entries >>> corrupt leaf that in turn prevents rw mounting. >>> BTRFS Standard Repair Tools are unsuccessful to fix what seems a small >>> localised error to a non critical directory. >>> I could not find any BTRFS type tool to remove just that directory >>> without the volume mounted rw. >>> And there is the catch 22 of not being able to mount it ro while the >>> "corrupt leaf" error occurs. >>> Initially btrfs rescue zero-log gave rw access. >>> I could not delete the "entries" directory associated with the Firefox >>> cache "entries" directory. >>> I was permitted to rename it so I renamed "entries" as "broken-inode-455338" >>> The system shortly thereafter set itself again to ro.
