    Failed deactivating swap /dev/pve/swap

    for me there is a web interface that manages the raid configuration, but I don't want to keep this setting disabled so this doesn't solves the issue for me

So searching with df -h I found that my root partition was around 75% on a 136GB sas 15k disk. At this point I was...

    Thank you @Chris for the reply, attached you can find the syslog in a timestamp around the reboot process, if you check at this is exacly when it stucks, but unfortunately I cannot see any errors. For errors checking with systemctl, I have to wait the week cause this is a production...

    Hi to all, in a 3 node ceph cluster buit on 3 identical hp gen8 dl360p servers, I'm always receiving the error attached everytime I'm rebooting a node.

    proxmox reports free memory not available

    thank you for your reply, with windows kvm servers I don't have any problems, this is happening only with kvm Linux. Baloon is enabled, I tried with fixed memory or different min memory too. If I'm correct with Linux kvm I don't have to install nothing for balooning to works. Am I right?

    replace sfp+nic in a ceph cluster

    I think that the only think that I can do is to create a Vbox environment similar to the production one, and then try to change nics and see what happens.

    replace sfp+nic in a ceph cluster

    I need to replace a 10gb sfp+ 2ports nic with a similar nic that provides 4 ports instead of 2. This particular nic is serving the internodal ceph network in a meshed network configuration, so no switches inside the ring. I'm in a production 3 node cluster with ceph and latest proxmox. replica...
