Stamps using Images don't work correctly in a clustered environment

[jkenyon]

Hi Team,

We have noticed that the stamps don't work correctly in a clustered setup with multiple LogicalDOC nodes. This is due to nodes storing stamps in different locations. This only seems to apply to stamps with images.

For example, if you create a new Stamp with an Image on NODE1, everything works fine on NODE1. However if you try to use this Stamp on NODE2 you get error like the following:

Caused by: java.lang.IllegalArgumentException?: Encrypted file not found in /dmsdata/plugins/logicaldoc-stamp/stamps/17858560

at com.logicaldoc.util.crypt.CryptUtil?.decrypt(CryptUtil?.java:90)

Likewise, if you create a new Stamp with an Image on NODE2, everything works fine on NODE2. However if you try to use this Stamp on NODE1 you get error like the following:

Caused by: java.lang.IllegalArgumentException?: Encrypted file not found in /opt/LogicalDOC/repository/plugins/logicaldoc-stamp/stamps/18710528

at com.logicaldoc.util.crypt.CryptUtil?.decrypt(CryptUtil?.java:90)

Not sure why each node is looking for stamps in different places?

Also as a result, the stamp image previews don't work - see attached.

Probably your setup is not correct, all the nodes must share the repository/ file system, please check the deployment scheme of a cluster here: ​http://docs.logicaldoc.com/en/clustering

You are correct. I checked our settings and for some reason the directory specified for the plugindir on node2 had changed from the shared directory to a local directory. Thanks.
