https://bugzilla.kernel.org/show_bug.cgi?id=201823 --- Comment #4 from matthias@xxxxxxxxxxxxxx --- The error occurs also with unmounted drive. Sorry for posting the output of the "xfs_db -r" command this is misleading. The first thing I did is checking it with a KNOPPIX 8.2 live CD. xfs_db is showing the erros but xfs_repair does not repair anything. Here the relevant outputs. /dev/sde1 is not mounted: ###### knoppix@Microknoppix:~$ uname -a Linux Microknoppix 4.16.5-64 #1 SMP PREEMPT Sun Apr 29 17:09:15 CEST 2018 x86_64 GNU/Linux ######
