<div>Looks indeed like an interresting problem. Did you try to

<div>The master might indeed store the workdir, but I would

<div>Which version of buildbot is that?</div>

the buildbot retain its memory of an earlier location of a<br>
buildslave? I've moved a buildslave to a different drive, but
the log<br>
from the new build tests shows the steps (e.g., the SVN,
ShellCommand,<br>
and Compile steps) all running from the original drive, not
the new drive.<br>
<br>
My buildbot runs on Windows 7 64-bit, and this particular
buildslave<br>
(called "centos7-worker") runs on a virtual machine on CentOS
7 (linux)<br>
hosted on the same Windows machine with the buildbot master.<br>
<br>
Originally, the buildslave's files were on a shared drive
(which is also<br>
a Windows share shared from the Windows host), in<br>
/media/sf_G_DRIVE/buildbot/centos7-worker, but the SVN
checkout step<br>
would successfully checkout only about half the project, then
give an error<br>

<br>
After a Google search turned up several mentions of conflicts
between<br>
Windows shared drive and sqlite (see, for example,<br>

rel="noreferrer" target="_blank">http://stackoverflow.com/questions/18782941/tortoisesvn-checkout-sqlite-disk-i-o-error-s10</a>),<br>
I moved the buildslave files to a local drive within the
virtual<br>
machine, with the path
/home/buildbot/Documents/centos7-worker.<br>
<br>
At this point, I expect the log to have references only to the
new<br>
/home/buildbot location, with no more references to the older<br>
/media/sf_G_DRIVE location. But instead, the log still shows
steps<br>
running "in dir
/media/sf_G_DRIVE/buildbot/centos7-worker/...". The top<br>
of the log from the SVN checkout step shows an example:<br>

------------------------------------------------------------<br>
<br>
I've tried recreating the buildbot master and both of its
buildslaves<br>
(deleting the master folder and the buildslaves folders,
creating the<br>
buildbot and buildslaves, then restoring the buildbot.tacs and<br>
master.cfg from backup). And I also unmounted the
/media/sf_G_DRIVE<br>
altogether. All of this seemed to purge the log as expected,
but the<br>
next build attempt still makes reference to the old location
of the<br>
CentOS buildslave in /media/sf_G_DRIVE drive.<br>
<br>
Where might the reference to this obsolete location of the
buildslave be<br>
stored? The centos7-worker's buildbot.tac file contains no
explicit<br>
reference to the obsolete location:<br>
------------------------------------------------------------<br>
<br>
import os<br>
<br>
from buildslave.bot import BuildSlave<br>
from twisted.application import service<br>
<br>
basedir = '.'<br>
rotateLength = 10000000<br>
maxRotatedFiles = 10<br>
<br>
# if this is a relocatable tac file, get the directory
containing the TAC<br>
if basedir == '.':<br>
import os.path<br>
basedir = os.path.abspath(os.path.dirname(__file__))<br>
<br>
# note: this line is matched against to check that this is
a buildslave<br>
# directory; do not edit it.<br>
application = service.Application('buildslave')<br>
<br>
try:<br>
from twisted.python.logfile import LogFile<br>
from twisted.python.log import ILogObserver,
FileLogObserver<br>
logfile = LogFile.fromFullPath(os.path.join(basedir,
"twistd.log"),<br>
rotateLength=rotateLength,<br>
maxRotatedFiles=maxRotatedFiles)<br>
application.setComponent(ILogObserver,
FileLogObserver(logfile).emit)<br>
except ImportError:<br>
# probably not yet twisted 8.2.0 and beyond, can't set
log yet<br>
pass<br>
<br>
buildmaster_host = 'kraken'<br>
port = 9989<br>
slavename = 'centos7-worker'<br>
passwd = 'pass'<br>
keepalive = 600<br>
usepty = 0<br>
umask = None<br>
maxdelay = 300<br>
allow_shutdown = None<br>
<br>
s = BuildSlave(buildmaster_host, port, slavename, passwd,
basedir,<br>
keepalive, usepty, umask=umask,
maxdelay=maxdelay,<br>
allow_shutdown=allow_shutdown)<br>
s.setServiceParent(application)<br>
<br>
<br>
Likewise, the master.cfg file creates a single SVN checkout
step as<br>
<br>
checkout = SVN(repourl = '<a class="moz-txt-link-freetext" href="svn://kraken/trunk/sf_code">svn://kraken/trunk/sf_code</a>',<br>
username = "buildbot",<br>
password = "buildbot",<br>
haltOnFailure = True,<br>
)<br>
------------------------------------------------------------<br>
<br>
and this step is used in all builders on both buildslaves (the<br>
"centos7-worker" and the "win64-worker"), so I don't see how
it could<br>
convey the obsolete location to the buildslave.<br>
