@dinhngtu i've manage to fixed it. Your build adds some extra entries in /var/lib/xcp/state.db that aren't in the version from testing that brake things when i downgraded the packages.
ipv4_dns
VIF.ipv6_dns
@pierrebrunet Thanks for the update.
So is there any way to run the reclaimSpace function (i.e from the XO CLI or something, without having to build a whole REST API application or whatever that involves)?
