I'm trying to use cephfs for isos. Prior to proxmox v6, we just created a mount point with /etc/fstab: none /mnt/isos fuse.ceph _netdev,defaults 0 0 That worked (and still does). Now I noticed PVE6 has a cephfs option, so in trying to do that, I receive a timeout when trying to add the...

Some NICs like Mellanox allow you to create "virtual functions" (basically a hardware-assisted virtual NIC). These are meant to be passed directly through to VMs instead of generating "tap" interfaces tied to a bridge. Supposedly this sort of thing completely hardware-offloads all...

We're currently building out a new 3-node datacenter that uses shared Ceph + Proxmox nodes. We've done this in the past using a classic LSI SAS3 RAID controller attached to a SAS3 backplane extender using all Intel DC S3700 SSDs (in JBOD mode) and have had good success. Now, with the new...

We've been using the same network configuration for about 2 years now with no changes, we use Open vSwitch. This issue appears to be intermittent, but sometimes on reboot, the bridge does not come up with the requested MTU size of 8996, instead it uses the default of 1500. This also means our...

Just curious if Open vSwitch 2.5 (the current LTS) is on the roadmap for PVE 4.2? It would definitely solve some issues for me (like rstp and multicast snooping). Thanks! -Brad

I've been trying to get this topology to work: http://pve.proxmox.com/wiki/Open_vSwitch#Example_4:_Spanning_Tree_.28STP.29_-_1Gbps_uplink.2C_10Gbps_interconnect However, I'm having issues where the proxmox to proxmox 10G interconnects aren't showing up as STP_BLOCK on all interfaces that it...

I didn't see any place to ask a pre-purchase question other than the forum. Not seeing any email or phone numbers on the proxmox.com website :/ We have a unique situation where we need to deploy the proxmox hosts in a PCI DSS (Payment Card Industry Data Security Standard) environment, and to...

I can consistently reproduce a VM lockup in my production environment. I install a CentOS 7 guest on a ceph rbd storage pool, and within that VM, I run: fio --rw=randrw --refill_buffers --norandommap --randrepeat=0 --ioengine=libaio --bs=4k --rwmixread=100 --iodepth=16 --numjobs=16...

I've been attempting to play around with the discard option in proxmox. When I enable that option, it seems I get random and unrecoverable lockups in the guest VMs (CentOS 7). The lockup doesn't appear to be disk-only, nothing works, console is unresponsive. Usually when I see a disk issue...

I'm having issues where multicast doesn't appear to work when I use openvswitch to configure my bonds and bridges. Initially at boot, everything comes up and the system has quorum, then in the logs you start seeing totem retransmissions on all systems and everything gets out of whack...

We are just starting to evaluate proxmox ve and testing the various features provided. The setup uses 3 Intel-based nodes with GlusterFS. Since we do not have an enterprise subscription (yet) we installed Debian 7.5 + GlusterFS 3.5, then performed the conversion to the Proxmox kernel using the...
