1297173 - Move 20 machines from Windows 7 pool to Windows XP pool

Status: RESOLVED FIXED

(Infrastructure & Operations Graveyard :: CIDuty, task)

Description

[Jonathan Griffin (:jgriffin)]

We have had very bad wait times on XP recently. With the move of more tests from hardware to AWS for Windows 7 (e.g, bug 1291015), we have the opportunity to rebalance the pools to increase the throughput for XP jobs.

Current pool sizes, according to arr:
XP - 122, w7 - 281, w8 - 194

Let's move 20 machines from w7 to XP and see how that impacts wait times.

Please file a relops bug when the releng modifications are in place and we're ready to do the renames and reimages.

We'll use t-xp32-ix-123 - t-xp32-ix-132

Added the new slaves to slavealloc, also removed the missing entries for the Windows7 slaves that were migrated to other XP pools.

delete from slaves where (name like 't-w732-ix%' and convert(substring(name,-3), unsigned integer) > 261 and convert(substring(name,-3), unsigned integer) < 282);

t-xp32-ix-125 (10.26.41.145) seems to not be re-imaged from t-w732-ix-264. It has been trying to sign on to bm127 as t-w732-ix-264, but the buildbot configs doesn't allow it. Renamed C:\slave\buildbot.tac and restarted so we don't get SNS messages about twisted.cred.error.UnauthorizedLogin.

I kicked off another reimage of t-xp32-ix-125

All 20 machines were successfully moved to Windows XP pool and are taking jobs.
