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.
