Otherwise, Bacula has to do it the slow way.
Hello, I thought that I explained differences in FreeBSD/Linux/Solaris sufficiently. Please - the problem is that FreeBSD does exactly what you tell it to do, OS EOM does mean HW EOM, where count of files is not held by SCSI specs. And OS FSF does mean HW FSF, where count of files is tracked. Unfortunately Solaris and Linux with some option compiled which I do not remember now, both try to be "better" and if you issue OS EOM, they both issue HW FSF with very big number. Both try to hide a feature of SCSI specification. I'm confident that this is the problem. In Bacula and on FreeBSD, HEOM has to be set to No, FFSF has to be set to Yes. This is exactly what Bacula needs: SCSI EOM (HEOM) is insufficient for correct Bacula functionality, so just FFSF may be used. -- Rudolf Cejka <cejkar at fit.vutbr.cz> http://www.fit.vutbr.cz/~cejkar Brno University of Technology, Faculty of Information Technology Bozetechova 2, 612 66 Brno, Czech Republic Using Tomcat but need to do more?
