    Upgrade cluster from 1gb to 10gb and add ceph

    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?

    HA with mix of storage (NFS and ZFS)

    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...

    pve-zsync only sync certain disks inside VM

    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...

    CEPH storage question

    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...

    Slow disk speeds on KVM guest

    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...

    qmrestore fails

    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...

    Directories missing after pct restore

    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...

    Preferred method to add local disk storage

    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?

    SSD / RAID question

    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.

    Strange fsck errors on loop1

    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...

    TASK ERROR: VM is locked (backup)

    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...

    Revert LXC containers to OpenVZ

    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...

    Slow boot times with lxc

    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...

    Proxmox installer question

    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

    zfs vs hardware raid

    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...

    Recommended ZFS setup

    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!

    Change default storage location

    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...

    Cluster hell

    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...

    Packet loss, network connectivity issues on new containers

    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...

    Migrate OpenVZ containers from an existing Proxmox install to a clean install

    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...
