trouble with AMANDA server (taper) on amd64 using Debian/AMD64/Sarge
2005-11-16 13:34:22
Hello folks ! I have been using AMANDA now for several years and find it to be a superb backup tool. I just converted one of my AMANDA backup servers (fea5) from an Alpha 64-bit machine running Debian/Sarge to a new AMD64 64-bit machine also running Debian/Sarge. When writing to the tape using the /usr/lib/amanda/taper component of the amanda-server package in 64-bit mode, the machine fails, and eventually hangs to the point of being unusable. However, if I issue the same commands in the chroot 32-bit mode environment, it works fine. Right now, I basically have to run the server in 32-bit mode and the client in 64-bit mode. I would much prefer running the entire system cleanly in 64-bit mode. I am including the taper error messages here for reference. Has anyone else experienced this problem ? If so how can it be corrected ? I have already issued a bug report to the Debian developers, but I have not obtained a solution and it has been several days
Partial list of the error messages (short enough to be able to send this e-mail to this mailing list):
