Subject: Q regarding booting from Mylex acceleraid170
Hi All
I have a Dell Poweredge 2550 with on board SCSI 7899 controller.
Can anyone give a brief overview (or point to one) of what a FS in FreeBSD
needs to do to interact with the rest of the OS? The general picture I've
got is of some code which interacts with the VFS layer above it and the
block I/O layer down below it. It is this correct? And what are the APIs

Hi, All.
A couple of friends are testing my DELACK backport, and their
initial run (pre-patch) of 'tbench' is, well, outrageous. My numbers
weren't anywhere near this bad.
Their boxes are functional, "production" boxes, one is 4.3R and the
other is 4.4S. Their hardware is [relatively] current; c

Yahoo noticed a deadlock in the vnode recycling code. If your machine
below is hitting the kern.maxvnodes limit it could be the same thing
If it's just for the exercise of porting a filesystem,
there are at least three filesystems available under a BSD
license:
1) Minix: all the OS was released under a BSD like license,
not to mention that it is perfectly documented.
2,3) NetBSD's ext2fs and LFS have surely been updated for
their UB

If it is a vnode deadlock you have to find which process or
processes it is deadlocking against.
Do a ps -axl -M vmcore.X -N kernel.X on the kernel core,
pick out all the processes blocked on inode or whatever,

How about writing a new filesystem based on UFS? This would save all of the
hassle that JFS would bring: licensing, porting time, etc. Of course, it
would likely bust any compatibility desired.
What I'm thinking is a filesystem that takes the current UFS and improves
upon it. It could support lar
It is possible that Kirk may be thinking about doing this. He mumbled
something about a new FS a while ago but it wasn't clear whether he was
thinking of doing it, or he was just saying "someone will eventually do
it".

Greetings,
Regarding the 'JFS for FreeBSD' discussion, I have

If it's based on UFS, it's not a new file system.

There are no hassles with licensing.
