I'm doing a overhaul of my cluster. Currently I have a 1GB switch connected to my cluster. I've installed 10gb nics and I also want to deploy ceph. What is the best process so I can use the speed of 10gb for transferring between nodes, install ceph but not break my cluster?

Recently I had both power supplies blow up on a TrueNAS server which had shared storage for several VMs. I'm now wanting to implement some HA for the critical services. On my large VMs I keep the important files on local (ZFS) storage and older non-important data on the shared NFS storage. If...

I have a VM with multiple disks inside a VM...one of the disks is a transcoding only mount and contains 200GB+ of exports which changes hourly. Is there a way to use pve-zsync and SKIP certain disks inside a vm? I've read the pve-zsync manual (6.x) and I don't see a way to do this. It...

Sorry, this isn't Proxmox specific but perhaps someone can help me understand. If I have a ceph cluster with 3 nodes with each node having 1 x 2TB hard drive is the storage 1:1 on the other nodes? If I have 500gb of video files will the total for all the nodes be 500gb used or would it be...

I have a zfs pool containing of 4 x 750GB "enterprise" sata drives. On the host and in containers I get fairly good disk speeds, however in a KVM guest the disk speeds fall on their face. I've tried various KVM disk cache settings including no cache, write back, write through and nothing seems...

I'm trying to restore a .vmz.lzo backup from an old version of Proxmox. However I get this error: root@rovio:~# qmrestore vzdump-qemu-110-2016_08_03-01_00_03.vma.lzo 110 Configuration file 'nodes/rovio/qemu-server/110.conf' does not exist It doesn't matter what I set the vmid to and I can't...

I backed up and transfered a LXC dump from Proxmox 4.1 to 4.2. When i ran pct restore (with the --storage local-lvm option) and started the container HHVM and other processes were freaking out and I noticed all of the directories and *some* of files in /var/log were missing. Has anyone seen...

I have a clean install of 4.2 on a 2 x 600GB SAS. The server also has a 2TB drive and a 500GB SSD that I want to use for non-important VM's and a backup of the VM's. What is the suggested method for adding storage with 4.2 and lvm thin?

I'm planning on deploying 2 x Samsung 850 Pro SSD's in a Dell R420 server and probably a 1TB HDD for backups. The server has a Dell H710 w/ 512MB cache installed. Is there anything wrong with doing hardware RAID-1 with 2 x SSDs? I'm not experienced enough to setup and maintain zfs.

One of my VM's is locking up with random filesystem errors inside the VM. Looking at the host I see these in the kern log: [Fri Mar 18 04:00:51 2016] EXT4-fs (loop1): error count since last fsck: 11 [Fri Mar 18 04:00:51 2016] EXT4-fs (loop1): initial error at time 1456211823...

Occasionally, usually every 2-3 days (I have nightly backups setup), my lxc containers freeze and 'pct unlock' won't unlock them and I have to reboot the nodes. This appears to be a common problem with lxc (I wish I would have stayed with openvz). Is there any solution to this? I'm backing...

I installed 4.1 and have issues with my LXC containers taking 5+ minutes to boot and also with them randomly freezing during backups (ssh and mysql connect but time out and the container has to be reset). I also want /proc/cpuinfo to show the correct CPUs and I want dmesg to only show logs for...

My LXC containers are taking 4+ minutes to boot. The console log shows things are booting fast then it stalls out at "Stopping populate /dev filesystem" for 3-4 minutes. ssh connections are refused until this finishes. Any suggestions? * Stopping flush early job output to logs...

If I have 2TB drives and 1 x 160GB SSD for caching would that be supported by the default installer or would it be 'better' to install onto a raid-1 setup and then setup zfs pools for the hhd + ssd cache for storage? Thanks

I'm looking at a dedicated server that includes a 32GB of ram, 2TB SATA and a 680GB SSD drive. Besides the obvious lack of redundancy, if I setup ZFS with the primary boot / storage for the 2TB drive and using some of the SSD for zfs cache would I expect to receive a decent amount of fsync's...

I want to try ZFS. Would I be better off with 2 x 160GB SSD for the boot / VM store (the vm's are small), or 2 x 250GB SATA with 1 x 160gb SSD w/ zfs for caching? I plan to run 5 openvz and 2 KVM servers. The server will be a E3-1230v3 with 32GB of ram. Thanks!

I have four nodes, each has 73GB for / (and currently /var/lib/vz). On a couple nodes I have additional storage that I want to use and make that the default location for those nodes. Is there a proper way to do this, or should I mount the new directories to /var/lib/vz? If I do that, how...

I'm struggling with a 4 node setup with Proxmox 2.3. My Dell switch does not support multicast, so I setup unicast. *some* nodes can see each other, but most can't. I am totally out of ideas, short of formatting and reinstalling (which would suck, this server is colocated so I'd have to do...

I haven't touched my proxmox server in about a month. I upgraded to the latest stable version and spun up a (new) container. I noticed that I had no network connectivity and so I thought it was a networking issue with one of my public IPs. I came back later and it started moving packets...

I'm moving between datacenters, and I need to copy my containers to a (clean) install of Proxmox. Once I move everything from the existing server to the new server, I'm going to take that server offline. How should I do this? I thought vzmigrate would do what I wanted, but after running it...
