If I do a tape dump, but instead write it to disk, e.g. dump 0auf - / >mydump.dmp (Which dumps the root file system to a file called 'mydump.dmp') - and then later either cp, dd or cat this to tape - why does a: restore t /dev/rst0 Give: tape read error: Invalid argument And: /kernel: st0(ncr0:6:0): ILLEGAL REQUEST asc:20,0 Invalid command operation code sks:c0,0 In the syslog? Normal dumps to tapes work fine... The exact error reported by the drive is 'block too big'. I've tried reblocking the dump with something like: dd if=mydump.dmp of=/dev/rst0 bs=512 But all to no avail... Anyone got any suggestions? Regards, Karl
