Subject: BTRFS Raid5 error during Scrub.
Date: Sun, 29 Sep 2019 23:38:55 +0200	[thread overview]
Message-ID: <804e7e93a00dfe954222e4f8dc820a075d9ccb79.camel@render-wahnsinn.de> (raw)

Hi guys. First off, I've got backups so no worries there. I'm just
trying to understand what's happening and which files are affected.
I've got a scrub running and the kernel dmesg buffer spit out the
following:

BTRFS warning (device sda): checksum/header error at logical
48781340082176 on dev /dev/sdb, physical 5651115966464: metadata leaf

Is there any way I can find out which files are affected so that I can
just restore them from a backup? 

I'm running Debian Buster with Kernel 5.2.
Btrfs-progs v4.20.1


Let me know if you need any further info.
