From Bugzilla Helper: User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.4.17 i586; Nav) Description of problem: The Rescue CD is missing the SCSI tape module, which makes restoring a system from scratch take longer. Also magic "mknod" doesn't understand SCSI tape devices. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Boot rescue CD 2. mknod /dev/st0 3. modprobe st Actual Results: The mknod fails since it has no knowledge of the st? devices. The modprobe fails silently. Expected Results: mknod should create the device. modprobe should find the st module and load it - it shouldn't fail silently. A simple "error loading" message would be useful. Additional info:
The problem also exists in rh73. You can create a new bootable disc1 that contains the st.o module like this: Install the anaconda and anaconda-runtime rpm's. cd /usr/lib/anaconda-runtime edit mk-images.i386 Look for SECSTAGE and change it into: SECSTAGE="st agpgart raid0 raid1 raid5 $IDEMODS $SCSIMODS $LATEUSBMODS $FSMODS" Edit mk-images In the makeinitrd function, look for fd1 and add the two lines: $MBD_DIR st0 c 9 0 644 root:root $MBD_DIR nst0 c 9 128 644 root:root After the EOF line, add: ln -s st0 $MBD_DIR/dev/tape ln -s nst0 $MBD_DIR/dev/nrtape This will create the necessary /dev entries for the st.o module. Follow the HOWTO http://www.linuxworks.com.au/redhat-installer-howto.html for creating new, bootable cd's You only need to burn disc no. 1 Boot, "linux rescue", and when the prompt comes, write: insmod st.o to load the st.o module.
This is added in CVS
OK, with the re0122.nightly tree, here's what I'm seeing. After normal boot, I can modprobe the st driver and get feedback about it loading. It's listed in 'lsmod' as well. In rescue mode however, the devices exist, but running 'modprobe st' returns without any output. The module is not listed in 'lsmod.' I have a machine sitting here at my desk if someone is interested.
I believe this is working - try modprobe st.o. Also you need to do this on a machine with a scsi tape - the loading of the st.o module should be automatic in this case when entering rescue mode.
Fix confirmed with the latest code.
