Hello, What suggestions do you have for where I should look next? I'm happy to = start installing various builds of FreeBSD in order to track down which = commit caused this. I'm trying to access a tape library from within a jail running on a = FreeBSD 11.1 host. sa(4) devices are working (e.g. I can rewind nsa0). pass(4) devices (i.e. the tape changer ch0) are not working. This = morning I posted to -scsi@: = https://lists.freebsd.org/pipermail/freebsd-scsi/2017-December/007608.html= The device appears in the jail and has appropriate permissions. This = access was granted via /etc/devfs.rules using the same approach I used for FreeBSD 10.3 The permissions in the jail: [root@bacula-sd-02 ~]# ls -l /dev/pass7 crw------- 1 root operator 0x74 Dec 16 21:52 /dev/pass7 The command in the jail: [root@bacula-sd-02 ~]# mtx -f /dev/pass7 status=20 cannot open SCSI device '/dev/pass7' - Operation not permitted Here is the truss output of the command in question: = https://gist.github.com/dlangille/b80ee804b8080e1cbf5b5ab67f0bdabe Thank you. --=20 Dan Langille - BSDCan / PGCon dan@langille.org
