| Hello, I'd like to setup some HA (active/passive) on our current Geoserver installation. For that I have configured two Geoserver instances in two FreeBSD jails: java1.prod.lan is the ACTIVE instance and java2.prod.lan is the PASSIVE instance. The two instances share the same data_dir, accessible through /filer/geoserver/data_dir which is a ZFS FS exported through NFS. To avoid possible corruption the shared data_dir is mounted read-only on the PASSIVE instance, but unfortunately it doesn't work (fall back to embedded data directory) because of the following code: https://github.com/geoserver/geoserver/blob/master/src/platform/src/main/java/org/geoserver/platform/GeoServerResourceLoader.java#L591-L665 The problematic code is:
if (!fh.canWrite()) {
LOGGER.warning(msgPrefix + " , which is not writeable");
continue;
My goal was to add stores, layers, etc on the ACTIVE node and then just log-in on the PASSIVE node and reload the catalog ... So my question is: why does Geoserver absolutely needs a writable data_dir/ for a read-only instance ? FYT this is the full log when I start the PASSIVE node: https://gist.github.com/silenius/f37e391e448d8fa3f9a6f88dac37e53a Thanks,
