Hello,
I have a problem which really should be straightforward but it keeps
bugging me. I want to append files to an existing gnu cpio archieve on
tape. I write an cpio archieve to the tape using the no rewind device
gfind . -blah | gcpio -ov > /dev/rmt/tps0d6nr
mt status
Controller: SCSI
Device: HP: C1533A A612 9
Status: 0x20260
Drive type: DAT
Media : READY, writable, not at BOT, block 1
it doesnt rewind the tape, so now i want to find a new set of files and
append them at the current position of the tape, into the existing
archieve.
gfind . -blahblah | gcpio -ov --append -O /dev/rmt/tps0d6nr
- this however produces this msg:
Found end of tape. Load next tape and press RETURN.
Apparently cpio writes an end of tape mark or end of archieve mark, which
cpio interpretes as "no-more-space" left on tape .. is there any way of
ignoring this mark or some other way to bypass it? Comments are very
welcome, or alternative ways to implement a working append-to-tape
routine. The streamer is HP scsi and it supports append operations, it
does NOT run on a fbsd based machine, so this mail might be way off-topic .. flame-away :>
