Description Alexandre Oliva 2005-03-21 09:20:02 EST
If I have one of my external HDs containing raid components connected to a USB
and one to a Firewire port, both are successfully brought up, as long as I
arrange for usb-storage to be loaded after sbp2: the sleep 5 after loading
usb-storage enables both buses to stabilize.

However, if I connect the disk that was on Firewire on a USB port, then, most
times, neither disk is brought up before raid devices are started.  It seems
that a little bit more than 5 seconds is needed for two disks to be detected and
brought up.

May I suggest that we extend the sleep to say 8 seconds, which has been working
reliably for me?  Also, how about arranging for such a sleep to be added after
the last of sbp2 and usb-storage, such that the order of scsi_hostadapter in
/etc/modprobe.conf doesn't affect whether Firewire disks work or not?  I'm
willing to implement and test such a change, if given a go ahead first.

FWIW, I don't need two external USB disks for the 5-second delay to be
insufficient: having a disk and my brand new USB mouse is enough to get the disk
brought up a tad bit too late for raid devices containing members in it to come
up cleanly.
