I've tried several methods, involving either creating one 512MB disk with mdconfig or mdmfs. No matter what options I specify, the mounted mfs works fine until I start filling it up more. For instance, I can usually copy the entire /usr/src/sys to /mnt and make depend, but a while after I make the kernel panics as a result of the ram disk. (specifically citing malloc errors, one time it speicifically spat out a number in the order of 251XXXXXX and indicated a malloc bucket limit exceeded or something like that) I've also tried making several (3x192MB) ram disks, mapping them as a single device with ccdconfig, then using /dev/ccd0 mounted with the appropriate newfs/mount commands. I get a different error (in fact rather than a straight kernel panic, I get several errors directly attributed to units on ccd0) I apologize for not having the kernel panic info, but I havn't been able to record it as of yet, and I don't have time to cause another panic right now. If that will help I'll be glad to try it again later this week and post the exact info. Thanks. -John To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
