My tape unit has been giving me problems on one server. So I did a dump over ssh to another box with a working tape like this: dump -0u -a -b 64 -f - /dev/da1s1e | ssh id@srv2 dd of=/dev/nrsa0 Then to check the dump on srv2 I did restore -i -f /dev/nrsa0 which came back and said the tape block size was different than the dump block size.... or something like that. >From my reading of the dump man page the -b parm controlled the block size of the chunks that dump wrote, but was NOT connected to the actual block size of the tape. Since this tape is a variable block device, I went ahead and set -b to the max... But now what do I do about restore? Is there a better way to control tape block size when piping through ssh? ie, dd of=/dev/nrsa0 bs=512?? But then what meaning does the -b parm have in dump? -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"
