I tried it once; rsync'ing a 100GB pool (with perhaps 5 or 6 million files) from one disk to another on a box with 512MB RAM and perhaps 1GB swap. the box eventually ran out of memory to the point that I had to power-cycle it to regain control. it's the only time in recent memory that I can think of a linux box needing to be rebooted for a software problem. I know of people who do it; but they're doing it on machines with more memory and fewer files. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com |
