Versions: mondo-2.2.0-2.fc5 mindi-1.2.0-2.fc5 buffer-1.19-1

Here's the command: mondoarchive -O -c16 -d /dev/hdb -I"/home/apf /home/public/data/PhotosFSpot"

I am suspicious of multiprocessor issues, due to the reference to libpthread, so I shall attempt to disable one processor.

Now that 2.2.2 is officially published on ​ftp://ftp.mondorescue.org could you check again if this has been solved or not.

Hi Bruno,

I've just tried out again, with latest versions of everything, and it all seems to have worked. The bug appears to be fixed,

thanks

Please do NOT use 2.2.2, but 2.2.3 instead. there was a nasty bug with bzip2 for 2.2.2.

Thanks for your feedback.

Hi Bruno,

yes I did the test with versions downloaded today (29th April 2007).

So I'm using mindi-1.2.3-1.fc6 mindi-busybox-1.2.2-2.fc6 mondo-2.2.3-1.fc6 kernel-2.6.20-1.2944.fc6
