Re: [Xen-API] XCP 1.6 BETA problem with pool-dump-database

I also find that if restart the pool (which means I shutdown all master and slaves then reboot all) all slaves will failed to join the pool any more. it will reported the slaves are deleted from the master. and it is unable to recover that and the only resolution I find is to reinstall the XCP in fresh clean mode (do not create local file repos during the setup) then rejoin the master from pool. The workaround now I have is to keep the master on otherwise it will be disaster.Â

I'm still struggling with this issue, but have observed something
interesting. ÂThe command executes correctly on the pool master
(xen3v3), and fails on a slave (xen2) with the 'database not in
memory' error.

Following is the xensource.log file on the pool master in both cases.
