"Waiting for Database Startup" after 2.0.5 upgrade

[jvestrum]

I ran the upgrade script for 2.0.5 and after 15 minutes the web interface is still displaying "Waiting for Database Startup", refreshing every 5 seconds. I've restarted httpd. My php.ini already has memory_limit = 512M. The elasticsearch process is running, but doesn't seem to be doing anything. No files have been modified in the data dir since the restart. Looking at the elasticsearch log, after the restart it only logged these three lines:

Code: Select all

Based on past restarts, those lines should immediately be followed by "using [1] data paths, mounts [[/srv ...." but it never happens. The process correctly has -Des.default.path.data=/srv/nagioslogserver/elasticsearch/data, which is where the data is and the permissions look correct.. I'm stumped.

Okay nevermind. This system had a hung NFS mount that was completely unrelated to the Elasticsearch install, but Elasticsearch was trying to do a df (or something similar) and hanging on that. As soon as I unmounted it, things got rolling again.

Glad to hear it got sorted out!
