    Hello guys, I updated my PVE Cluster yesterday to the newest Ceph Version and did not notice any issues at first. The VMs and CTs do run normally, I can read and write to the virtual disks, even create new ones, just fine! Migrating between Nodes also works, as well as deleting CTs... But...

    CEPH issue: continuous rebalancing

    Hi! I've got 3 node PVE cluster with CEPH. 1 pool, 4 OSDs per node Yesterday CEPH started rabalancing and it still goes. I think this because I've added abot 6Tb of data and autoscale changed pgs number from 32 to 128. It's ok but I'm bit confused because it's doing recovery fine until 95% is...

    Is it possible to create a high-performance cluster using only two PCs with Ceph? What are the correct configuration steps?

    I have two PCs, each with 16 GB of RAM and 500 GB of SSD storage. I have created a cluster in Proxmox with them, but when running PowerBI in the first VM of the first node, it does not share the load with the other node. How can I create a high-performance cluster? I am looking to optimize the...

    Ceph krbd - Disk 0 bytes after resize

    We recently enable kRBD (tick the KRBD box in storage configuration) for our running cluster. Faster IO was the main reason, We record 30% gain in reads/writes in all VM running in writeback cache mode. But then a couple of VMs disks needed to be resized. In both cases disks went to 0 bytes...

    Advise on ceph additions: RGW, NFS, iSCSI

    Hi, Does someone have a few pointers about this setup? I want to install a ha object store and eventually some NFS volumes, using our ceph-installation, to use for our internal k8s cluster. Is it better to get this virtualized to avoid upgrade issues on the physical hosts? Does ceph-dashboard...

    Can you mount CephFS on PBS as Datastore?

    Hello guys, we have a PBS running in our Dev-Environment with a Tape-Lib attached, but as I found out, you can only backup to tape if the backups are on a Datastore beforehand... Originally I was planning to backup directly to tape, so I deployed a 1U PBS Server that barely has enough space for...

    Is it safe to use same switch for CEPH and CLUSTER networks?

    I'm planning a 7nodes proxmox cluster. Of those 7nodes, 3 will have a ceph shared storage. Each node is equipped with 3x RJ45 and 2x SFP+ network interfaces. I know that is best to have separated networks for CEPH, PROXMOX CLUSTER and LAN, but I was thinking if is a good Idea to use a setup with...
