Hi,
I have a installation of Plone 4.3.3 with one site. First the buildout was
configured to use the Data.fs file in var/filestorage and a shared blob storage
in var/blobstorage. Then I added a Relstorage to the buildout and converted the
content of the Data.fs file to the underlying MySQL database. Now Plone is using
Relstorage instead of Data.fs.
But now I want also to use the Relstorage for the blobs. Because I am relatively
new to Plone and especially the Relstorage thing, my idea was to first setup a
new empty Plone. Then I copied the buildout.cfg and base.cfg from the first one
to the new one. Then I created a new database userZodb and changed the base.cfg
for using the new database and I also changed the ports for zeoserver and
clients. The next step was to reconfigure the relstorage for not using the file
based blobstorage.
rel-storage =
type mysql
db userZodb
user zodbuser
passwd innzop
blob-dir ${buildout:var-dir}/blobstorage
shared-blob-dir false
# shared blobs are much faster if we're on the same server.
# if not, turn it off.
shared-blob = off
Then I ran the buildout. All was built successfully. After starting the
zeoserver, I got this error from the client:
user@server:~/Plone433-dev/zeocluster3$ ./bin/zeoserver start

ValueError: Directory layout `zeocache` selected for blob directory
/home/user/Plone433-dev/zeocluster3/var/blobstorage/, but marker found for
layout `bushy`
Unfortunality I have no idea where the problem could be.
I think the best would be to simply disable blobstorage completely. This way
Plone would be forced to use filestorage respectively the Relstorage for the
blobs. So I decided to comment out all lines defining "blob-storage =
${:var}/blobstorage". I thought Plone would now using Relstorage for the blobs
too. But after the buildout there is still the following line in
parts/zeoserver/etc/zeo.conf:
blob-dir /home/openmind/Plone433-dev/zeocluster3/var/blobstorage
Why want I do this? Because our customer wants only one big MySQL database which
stores filestorage and blobstorage. So he can backup his system easier. I know
this is not a good idea, but he wants so.
Any suggestions? Thank you!
