Hi all, I'm using a SuSE Linux (V7.2) with a 2.4.4 kernel. If I start a program which reads from a snapshot (e.g. cat /dev/vg/snapshot > /tmp/file) with a low priority (nice -20), sometimes the program hangs within the read() call if the snapshot gets full. If this is the case I'm not able to kill the process of the application (even SIGKILL). In my application I reduced the number of blocks in each read() call reads and I stop reading after the snapshot is full of more then 90%. But this solution is not completely avoiding the problem. Is there any fix in a newer kernel version? Thanks for any ideas! Martin
