Hello Carsten,
Thank you for the quick reply, we tried many different combinations, without the -m flag the result is the same.
New gdb dump in the attachment replacing the -m with -v

At the very least (though I'm not sure if that will already fix it) I
think you need to change the -m flag:
/usr/sbin/xfs_repair -n -P -m 500000000000000 /dev/sdb1
according to man page:
-m maxmem
Specifies the approximate maximum amount of memory, in
megabytes, to use for xfs_repair. xfs_repair has its own internal block
cache which will scale
out up to the lesser of the process's virtual address
limit or about 75% of the system's physical RAM. This option overrides
these limits.
NOTE: These memory limits are only approximate and may use
more than the specified limit.
and I doubt your machine has that much memory, possibly just drop it for
now.
Cheers
CarstenStarting program: /usr/sbin/xfs_repair -n -P -v /dev/sdb1
