Message-ID: <20200520155428.GA1810@ehud.gomer.local> (raw)
Hallo,
https://btrfs.wiki.kernel.org/index.php/Tree-checker suggested that I
ask here for help.
When I run a Linux-Kernel 5.7.0-rc2, compiled with pretty much
default configuration, and try to run
ls /vservers
I get the error message:
ls: cannot access '/vservers': Input/output error
From dmesg I get:
[912737.466820] BTRFS critical (device dm-2): corrupt leaf: root=5 block=350945280 slot=85 ino=55495, unknown flags detected: 0x2000000

With kernel 5.6.9 I get:

With the default kernel of Debian “Stable” = “10” = “Buster”, which is
presently 4.19.0-9 this works flawlessly. When I booted my computer
with grml 2018.12 ( https://grml.org/ ) with a 4.19.8 kernel, I didn_t
have any problems either, “btrfs check” and “btrfs scrub” didn't find
any errors.
Has there been a change to tree-checker, that has a problem with
something vServer ( http://linux-vserver.org ) does? I don't use
vServer any more, since Debian stopped supporting it, I only keep those
files for reference.
I don't think that matters, but I have three SSDs in a RAID0 Array,
on top of which there is a LUKS container which contains a LVM2
which in turn has the BTRFS file system in one of it's LVs.
Is there any other information You need?
Greeting,
Joerg
