it will be difficult to copy a 17GB with a 50M cache. you might want to consider a much larger cache and a larger chunksize. this should reduce the thrashing somewhat. increase your cache to 1048576, and add -chunksize 20 to the OPTIONS in /etc/sysconfig/afs. >I cancelled the cp(1) process and as I'm nasty user, I tried: > ># umount /afs >Segmentation fault it should not do that. i need to think about this for a bit. in the meantime try a bigger cache. _______________________________________________ OpenAFS-devel mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-devel
