puppetdb startup fail - after move of datadir

[Klavs Klavsen]

My puppetdb fails with this message:

I moved /var/lib/puppetdb to a new disk - mounted under /mnt/puppetdata - and bind mounted /var/lib/puppetdb to /mnt/puppetdata/puppetdb (which is where I copied the data).

I have disabled selinux - and ownership of files, remains puppetdb.

I can't figure out what to look at next - and that error message doesn't give any google results that seems usable..

Any hints?
