Adam,
We have been getting 3Ware 9500 series adapters in the past 60 days
which exhibit a delayed behavior during mounting of FS from
/etc/fstab. The adapters older than this do not exhibit this behavior.
During bootup, if the driver is compiled as a module rather than in
kernel, mount points such as /var in fstab fail to detect the devices
until the system fully boots, at which point the /dev/sdb etc. devices
showup. It happens on both ATA cabled drives and drives
cabled with multi-lane controller backplanes.
The problem is easy to reproduce. Install ES4, point the /var directory
during install to one of the array devices in disk druid, and after
the install completes, /var/ will not mount during bootup and all sorts
of errors stream off the screen. I can reproduce the problem
with several systems in our labs and upon investigating the adapter
revisions, I find that adapters ordered in the past 60 days exhibit
the problem. Compiling the driver in kernel gets around the problem,
indicating its timing related.

Jeff,
Can you reproduce with 2.6.18.1? ES4 contains a custom 3ware driver.
Also, you have included no error output with this email whatsoever. Can
you go to a virtual console during your ES4 install, run 'dmesg', and see if
the errors are in there, or if they are a part of the ES4 anaconda installer?
/dev/sdb, etc. having delayed appearances sounds like it is udev related.
Are you running the latest firmware? Do your controllers older than 60 days
have different firmware?
I will try to reproduce this.

We don't use kernels later than 2.6.15 in our shipping releases since
they have
some issues with stability.

dmesg produces no output since the errors are reflected from init.
Errors are typical of an unmounted volume. i.e.
"cannot touch /var/lock/subsys/<service> (dozens of these)
Starting System logger (hangs for 15 minutes)
So no logs .....

No, I do not believe so.

This is the right question. I will collect the various versions this
occurs on and post them here.

Pretty easy to do.
