Hi, John R. Jackson schrieb:
AFAIK, if I'm invoking amcheck, then this programm starts the changer-script and waits with waitpid() for the end of the changer script, but the changer-script ends to quick and then waitpid() returns an error. This must be a timing problem, as a said if I add a sleep i the changer-script then it works better, but not completely.we wrote our own request() function.And what's in your version of the function? My guess is it is not waiting long enough for the tape to go ready. What's in /tmp/amanda/changer.debug?
The weird thing was that when I'm invoking the amcheck (or amdump) from the commandline, then it works perfect, only when starting from cron this doesen't work.
We have the same scripts on other machines running for more then a year with no problems, but on this machine it doesen't work.
We use the changer scripts for avoiding that amanda puts the dump on the holding disk if no tape was inserted, instead using our scripts amanda, waits for the right tape and after the right tape was inserted amanda starts with the backup.
however, I disabled the changer-mechanism and now the backup works.
thanx,
bye,
