The -q option tells xfsdump/xfsrestore that the tape is a QIC tape. QIC tapes
use only 512 byte blocksizes, so xfsdump/xfsrestore need to make special
allowances for this.
This is a Linux only option. On IRIX, xfsdump/xfsrestore are able to
automatically detect QIC tapes.
If you get messages like:
xfsdump: unable to set block size to 1048576
or try to specify a 512 byte blocksize with -b, and then get an assertion
xfsdump: drive_scsitape.c:1985: do_get_write_buf: Assertion
`contextp->dc_nextp < contextp->dc_recendp' failed.
then you _might_ have a QIC tape that requires this option. This option
has been in the Linux xfsdump/xfsrestore since the initial port, but hasn't
