    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?

    lxcfs segfaulting after upgrade to 6.2 (lxc 4.0)

    [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?

    [SOLVED] Parallel startup for LXC Containers possible?

    Hi there, having >200 LXC Containers on a Server takes some time to bring all up on a Node Reboot, especially when they are started in a serial manner. Is there a possibility to work with parallel starts to bring up the containers faster?

    [SOLVED] CEPH OSD Nearfull

    Hi, wir betreiben einen 4 Node Cluster mit CEPH als Storage (alles PVE Managed). Heute morgen ist eine OSD auf Nearfull gesprungen, und der Pool dazu scheinbar auch. Was ich nicht ganz verstehe: 67% used vom Raw Storage aber 85 vom Pool? Liegt das evtl. am Verschnitt durch "size=3" ...
