    VLAN's across hosts in a cluster

    is VLAN 10 enabled on the switch side ? did you test if O2#1 works ? if you test that then you narrow it down to VM level, if that doenst work than its probably switch config

    there are 2 ways todo this We call it Option 1 and 2 (O1, O2) either you want vmbr1 pass VLAN10 as native traffic to the vm. in that case you need todo nothing in the vm except set the interface to vmbr1. with again 2 ways todo that. o1#1 do it on the switch and simply pass VLAN10 as native on...

    PVE Firewall and MTU little trap

    I just stumbled across a little nasty trap. When not setting the firewall check mark in the Network adapter, MTU doesnt seem to be set or taken from the Bridge by default. However, the Moment you activate the firewall Check mark MTU will be forced set to 1500 This can be a very nasty trap for...

    Nodes lose network connectivity when I reboot the switch and do not get it back after switch reboot is complete

    my corosync suggest its really not that complicated, you can set it up within 5 minutes. just define 2 new tagged vlans and add one of each to each of tghe mellanox ports so lets say vlan 100 and 101, you add vlan 100 to all ports using mellanox port1, and 101 to all ports using mellanox 2 (i...

    New Cluster some basic questions

    yea i know but the idea is to get failover for the internal gateway. so if one machine has to reboot still another one answers. main sender is a software that will simply discard that mail without notice if the defined server times out (stupid i know) . and we have about 1-3k mails per day. but...

    Nodes lose network connectivity when I reboot the switch and do not get it back after switch reboot is complete

    uhm why so many bdiges on different interfaces ? where is your corosync interface ? you should have at the very least one interface (probably eno) - active, not assigned to a bridge, as a corosync interface as for unifi, CAREFUL, this symbol is NOT STP Blocking, the UI is misleading. unifi...

    "VLAN aware" checkbox has no function

    ofc it is you dont understand the feature. ok if youre not vlan aware, the vm is running on vlan 0 aka untagged, and ofc all tagged also gets passed. in that case we need to config within the vm itself to go trough tagged traffic and associate additional interfaces for it. if vlan aware is...

    [SOLVED] BTFRS Swap-Partition

    please consider the real pupose of swap. it is not for extra ram, it is not as emergency ram (even tough it works as such so system doesnt lock up and kernel oom has time to clean up to prevent a freeze) But main purpose is memory organisation and its incredible important for it. without it we...

    [SOLVED] PBS no longer working after upgrading host to PVE 7

    never said its a good idea, but main version is still the same and hasnt change since 2018. and having a defunct pbs is even worse as having a halfway broken one: question is what PBS does with the scsi tools. if its just to initialize storage or read out diskinfo then it should not affect...
