or.
iso9660 rr name=USR1 source=/usr1 > /tmp/image
This example generates an ISO 9660 image from the directory tree \usr1
(or /usr1) with Rock Ridge extensions.
CD can also be copied, if you have a second drive, e.g., \\.\p0b0t3 or.
/dev/iXOS_SCSI0/3:
cdglow -v -s \\.\p0b0t3 -t \\.\p0b0t6
or.
cdglow -v -s /dev/iXOS_SCSI0/3 -t /dev/iXOS_SCSI0/6
These commands copy one Cd to another and verify the results. It is im-
portant, however, that the source CD is faster than target CD. If this is not
the case, then the options -f1 or -f2 should be used to lower the speed
of the recording process.
Messages
cdglow produces message which each begin with the time in hundreds of
seconds. From these messages it is possible to see, e.g., which device
was found by cdglow, how many blocks of data should be written, how
much data has already been read into the buffer, when the recording
process has ended and when the CD has been finally made ready for
reading. If you use the option -v, then an additional verification is carried
out by comparing the source and the target. Should there be a difference,
the number of and identity of the blocks which differ is output. The source
and target should, of course, be identical, but should any errors occur
during the transfer of data over the SCSI connection, it will be indicated
here. If a verification is successful, the output code should is 0.
Should an actual error occur, an error message is output. In such a case
two error messages are usually output. This arises from the fact that at
the beginning of the recording, cdglow splits into two threads witha view
to maintaining the required data transfer rate. This has the advantage that
if one is interrupted, then the other acts as a backup process.
Production of CDs in jukeboxes
Unlike our Jukebox-Server, cdglow has no knowledge of jukeboxes.
However, it is possible to produce CDs with the help of this server.
Note that as of version 2.1 of iXOS-JUKEMAN, you do not need to set up
two different device description files or to change the only device descrip-
tion file in order to reserve a recorder for writing, as you had to in previous
