This also impacts the plan to deliver compact flashes as a solution to
our upgrade problems.

=20

The procedure I wrote in essences says "install the new compact flash
and then do system copy config."

Now it seems this won't work.=20

=20

Here is a proposal that I am offering for consideration. After a system
config reset the rc script runs a configuration script. What if we add
an option to copy the configuration from the secondary flash and add the
copy commands to the script?  It is not a completely inelegant solution
and I find it useful.

=20

I don't think it would take too long to implement this solution.=20

=20

The release notes would then be something like; "install the new compact
flash; reboot; choose option (N) to reconfigure your system with
previous data."

=20

Let me know what you think.

Guys, the goal is to upgrade MD today if possible.   Apparently QA never
tested a 2.2->3.0 upgrade.    This needs to be higher priority than
other Delorean defects.    Please review this.   Thanks.

Subject: Blocker issue for MD upgrade to 3.0

=20

We just ran into this issue when trying to copy the config files from
our 2.2 cluster to 3.0 brand new flash running sub#16. This is related
to old and new CF layout.

=20

System config copy is not looking at the standby flash fstab to mount
the devices it needs to copy the active flash configuration files.

Since the names of the devices have changed between the 2 layouts, it's
trying to mount a device that does not exist on the standby flash.

=20

When we tested this command earlier, we did not run into this issue
because we were using 2.3 old and new layout, and I just found out that
the system config copy command has been fixed in 2.3now3.0 to look at
the fstab from the standby flash.

=20

Workaround would be:

- mount each device manually to copy the config files

Or

- run system upgrade -s (this one should work since 2.2 already had the
bom file and first upgrade changes) but we would run 3.0 with old CF
layout

=20

Final solution could be:=20

- rename the partitions of the new layout to map with fstab of earlier
releases, if possible
