Hi,
How Mac OS X handle this? Method, tricks, code, etc...
Does Linux reboot when this happen?
One can argue the kernel is so different between OS X, Linux and FBSD,
but it is still better to compare WIN vs FBSD (or NTFS vs UFS).
Or may be I am wrong.
BTW,
I hardly ever put a USB Disk on our FBSD Servers,
but never had problem disconnect USB/Firewire Disk on my Powerbook.

This is very interesting thread indeed....
I have found that mounting remote SMB shares will panic the kernel
too, but
only if i try to access it while 'gone' . If I remember correctly,
if i thread
carefully around it, i can manage to shutdown everything and it
will only panic
at the very last minute when the kernel tries to unmount.
And, from my point of view, the explanation 'well, don't remove
your mounted
devices without unmounting them first' is rubbish - the problem is not
necessarily users removing them, but ALL the reasons that could
cause an
unwanted and unplanned removal. Like a network outage in the case
of smbfs. or
someone killing the power on a USB device. I can't see why the
whole kernel
should die on you. Yes, i understand there are architectural
reasons for this -
then the architecture is not right anymore, i think.
another work-around
is to use the auto mounter daemon (amd(8)). It umounts
file systems automatically that are not in use.
Another nice feature of amd(8) is that you don't have
to mount the file system either -- Simply plug the USB
stick in, then access it, and amd(8) will automatically
mount it for you.
Now, something I dont understand - amd runs
at user level, and it mounts filesystems, and nothing dies when the
filesystems
go away (other than the obvious cases for the applications trying
to write to
the FS in question). Doesn't amd , at some point , have to tell the
kernel
'please mount this filesystem' here or there? Isn't the kernel
STILL involved
in all this? and why doesnt the kernel panic when the FS goes away?
The same goes for hald - it doesn't work flawlessly, but it does
the trick, and
i cant recall an instance when it crashed the kernel.
re. USB disks, could we not by default use amd to mount USB
devices? It seems
the obvious native replacement for hald + polkitd + dbus I use in
XFCE with
Thunar on my laptop...
TIA!
