    Strange Firewall/ipsec behaviour after upgrading to 6.2-11

    I have recently updated a cluster with a few nodes having pretty similar network setup. Each node is connected with a few external networks over ipsec. And just one node behaves crazy (this is really strange). I can't ping any of the networks that are tunneled through the ipsec. Tunnels are...

It worked all the time flawlessly and best suited my needs (of course no shared storage, LM or HA but still central management, easy offline migrations etc). Some time ago I've upgraded to PVE 6.0 and was able to run the...

    Best practice for ZIL/L2ARC with just 4xSSDs (yet another one :)

    I know this subject was discussed so many times... I have read so many tutorials and so many "best practices" and "suggestions"... Sometimes they advise exactly opposite things... After reading another one I decided to ask community advice before I start :) I am building Proxmox VE setup based...

    Base template on SSD drive - how good is the performance improvement?

    Actually the subject says it all... I have a server with ZFS where I have 2xSSDs in mirror where proxmox installation, L2ARC and ZIL reside. Then a bunch of 10k HDDs in a pool where the VMs are running. On a different forum thread I have read that a) using linked clones does not affect...
