Every disk drives can be found by several means in /dev/ directory. LVM commands can b told which ones to prefer in /etc/lvm/lvm.conf. Fot my HP and Dell servers, I use this : in devices {} section : preferred_names = [ "^/dev/vg", "^/dev/mapper", "^/dev/[hs]d", "^/dev/cciss" ]

For this problem, try to use the _netdev mount option in fstab (see man mount). It waits for network to start before mounting the filesystem.

Kill the vztar child processes, vzdump can continue and terminate properly, removing LVM snapshots.

Hello, I'm in a really similar configuration (BL460c G6, HP EVA 6000/8000), but I'm still on the stable 2.6.18 kernel. You're using pve-kernel-2.6.32-3-pve, there is an update : 2.6.32-4-pve. It seems like your storage hang.With FC, you certainly use multipathing. Can you show us your config...

Hello, DRBD is TCP/IP only, but I know it is possible to do TCP/IP over Infiniband, so it must be possible. Concerning performance, with Infiniband you'll get good network latency but certainly less than a local drive... Be sure to get a battery backed write cache with your RAID card, this is...

Ah, I forgot to say that the virtio drivers are the ones in virtio-win-1.1.16.iso.

Hello, A collegue has made a Windows installtion ISO including the KVM virtio drivers. We can install Windows 2003 server directly on virtio disks without messing with a floppy or switching from IDE to Virtio. All was fine until I upgrade one server to PVE 1.8 and to test, I use a 2.6.32...

You can also run NFS server on each server, declare them as backup storage, and make cross backup of each Container of machine A on backup storage on machine B and vis-versa. It's more clean than rsync, but perhaps less fast. PS: With the rsync method, I would not copy /etc/vz/conf directly in...

Real HA will only be in 2.x versions. To have a manual recovery mode, you just have to backup /etc/vz/conf for OpenVZ VM and /etc/qemu-server/ for KVM ones. You must use shared storage, but you do with DRBD. If a server crash and you can not restart it in an acceptable delay, restore the...

You missed something. Of course we can have Linux guests with KVM and KSM.

If you restore from a snapshot taken live on your storage système, it will be the samle as a LVM snapshot with proxmox. The result can work, it will be the same as a a power failure. On databases, or other applications holding data in RAM, it is a bit dangerous. Also, snapshots on a storage...

I use elevator=deadline at boot time, and I don't see any problems with my OpenVZ containers. I don't use and don't know how to use the IO priorities you talk about...

Re: vzdump of KVM in snapshot issue-took 30 minutes for 18 GB disk If I had correctly understood, the problem is more that the snapshot mode does not work than the backup duration. If the snapshot mode of vzdump was chosen and functionnal, the VM should be unresponsive for 2 or 3 seconds, not...

If you have a shared storage, monitor the vgs process on the node where you look at the hardware tab. I use a simple loop like : while true; do ps -ef | grep vgs; sleep 1; done But if you haven't got enough devices, it will probably be too fast to be ssen. Because, not only have I 80 VGs...
