    [SOLVED] after upgrade Mellanox issue . can not connect to ceph network

    Sorry, but without an error message i can't help you ¯\_(ツ)_/¯ try sneaking around in /var/log/ceph and look at the logfiles, or try pinging nodes on the ceph public network, or check if the interface came up .. or or or

    Help wanted ipv6

    what does your ip6 routing table look like? ip -6 ro from the ip 2a01:4f8:141:3e4::1 guess you're at hetzner, they tend to use fe80::1 as gateway... but you don't - maybe thats your problem?

    [SOLVED] PVESIG - what is it used for?

    Hi there, i was wondering what the PVESIG in the iptables rules are for. Is there any sort of "tampering" detection (and mitigation?) or what is it used for?
