I adjusted the file system parameters to 64KB block size, 8KB fragments to improve performance. I also compiled soft updates into the kernel. When you try to active soft updates on the filesystem (tunefs -n enable /dev/....) the kernel panics right away with a "dirty vbufs" message. >How-To-Repeat: newfs -b 65536 -f 8192 -i 262144 /dev/rda1s1e tunefs -n enable /dev/da1s1e <kernel panic "dirty vbufs"> >Fix: Use the defaults when creating the filesytems with newfs. Soft updates work fine with the default 4KB block size. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
