I'm seeing this as well. I'm not familiar with the internals of amanda and have been doing some hacking....
If I try and run taper interactively.. and give a START-TAPER command: $ /usr/lib/amanda/taper DailySet1 ... debug buffer stuff ommitted ... taper> START-TAPER 20060425 changer: opening pipe to: /usr/libexec/chg-zd-mtx -info changer: got exit: 0 str: 1 1 1 changer_query: changer return was 1 1 changer_query: searchable = 0 changer_find: looking for Daily102 changer is searchable = 0 changer: opening pipe to: /usr/libexec/chg-zd-mtx -slot current changer: got exit: 0 str: 1 /dev/nst0 $ ( goes straight to command prompt ) If I comment out tpcchanger in amanda.conf, it works! (I get a TAPER-OK message). If I delete the /etc/amanda/Daily/chg-zd-mtx* status files, I can go back to the changer again.... TAPER still doesn't write to tape though... (no error, IIRC) For now, I'm going back to 2.4 so I can flush the holding files to tape, then I'll reload 2.5 and start trying to troubleshoot again.. Robert
