I hope sombody can help me with this problem.
I have had to physically move our server, and
though connections and tape drives are the same, backups no longer work.
The tape drive can be written and read OK using tar, for example,
but not using xfsdump. A truncated example follows ...
xfsdump: RLIMIT_AS org cur 0xffffffffffffffff max 0xffffffffffffffff
xfsdump: RLIMIT_STACK org cur 0x800000 max 0xffffffffffffffff
xfsdump: raising stack size soft limit from 0x800000 to 0x2000000

xfsdump: RLIMIT_DATA org cur 0xffffffffffffffff max 0xffffffffffffffff
xfsdump: RLIMIT_FSIZE org cur 0xffffffffffffffff max 0xffffffffffffffff
xfsdump: RLIMIT_FSIZE now cur 0xffffffffffffffff max 0xffffffffffffffff
