Subject: DeLorean Submittal 22 Ready for Acceptance Testing - Was: RE: =
Please include this in sub #22



Here is submittal 22 for DeLorean 3.0.0.0 including the cw_install =
standalone install script that facilitates one-step upgrades from 1.3.x =
and 2.x to 3.0.

The changes since sub21 are these three:

Change 24169 by andys@ripper on 2007/06/04 09:59:34

      Nice down "tar -zx" process to increase responsiveness of =
managment processor
      during upgrades, hopefully putting an end to silent reboots during =
upgrades.

      TED00018378 - "Cheetah Upgrade of 2nd flash from =
1.3.3.15->Delorean#11: Silent reboot"

Change 24171 by andys@ripper on 2007/06/04 13:56:21

      First checkin of standalone Install script and related changes.
      If we've all been living clean lives, the last checkin.

      TED00018276 - "Upgrade from 2221 to 2.3 on secondary flash fails =
to copy files"

Change 24188 by jobia@jobi:jobi on 2007/06/05 12:22:27

         Fix a watchdog timeout in fs_buddy_bnum_in_free_region().

         Defect TED00019400.

EverON images ( prior sub21 images have been renamed with a '-sub21' =
suffix ):

Cheetah optimized:

ftp://upgrade@10.2.0.2/home/upgrade/EverON-3.0.0.0.tar.gz

Bobcat debug:

IMPORTANT NOTE: To test the cw_install.sh script you must use the =
version corresponding to
the EverON variant you are using., i.e. cheetah debug, bobcat opt, etc. =
At the moment, the
cw_install.sh script is built into the tarball it's supposed to support, =
so there
must be workflows designed and tested to extract the file, etc. for the =
customer. Right now their are
four versions of the file cw_install.sh that have different contents and =
must be managed separately.

In lieu of that, internally I am posting all versions of the script on =
both the FTP server and under
Build-Trees for build distribution.

We need 2 things for sub22:



1.      the P4 changelist #24171 includes a changed openbsd file.   =
Since it doesn't need to be compiled (/etc/rc) I suggest simply patching =
this into the latest BSD build rather than do a full BSD build, if Ken =
agrees after reviewing the changelist.
2.      merge the fix for CQ #19400 from Zonda to Delorean & have Jobi =
review the merge

I'll confirm w/ Andy that this is ready.    So that would be 2 builds, =
sub22 this week and sub23 next week w/ more MF fixes.

I like to complete 40 TB by 6/15. So we need a build ASAP since it takes =
time to create data.



Also Paul has asked us to start with CW-install tests, so we need to =
build.

But is the 40TB testing happening this week or could this wait for the =
next build, likely early next week?



I'd prefer to do one more build, if possible, but we may need 2 if you =
need this fix sooner.

I think completing the 40TB test should give us enough test coverage for =
this change. We should take this

I had been considering this one, and Sandrine and I had discussed it as =
a possibility.   On the other hand, I also want to stabilize the code =
base and minimize the checkins.



What is the test impact?

Is your filesystem becoming almost full frequently?

If your intention is to populate 40TB, you may temporarily disable the =
snapshots.

Also if this is an absolute showstopper for you, we may port the fix to =
delorean.

Jobi
