Are you using soft raid on the OMV box? Why RAID0?! What does your backup solution look like? What's the purpose of having three nodes?

Seems to be working. My FSYNCS were still pretty slow though even with the SSD cache/logs drive at around 400. Actual performance seems to be okay, busy restoring a backup from a USB 2 external drive. Will only know when I start working with the VMs. While copying from external...

Thanks, I've gone with a 20/80GB split. Will see how it works out.

How exactly do you partition the SSD? How do you determine the size of each partition should be?

I just installed a new SSD and trying to do some performance tweaks before moving VMs to the box. I initially thought ext4 would be the better option as it's the more modern filesystem. When running pveperf though I was a bit concerned with the low FSYNCS/sec as I thought SSDs would kill at...

Just remember that you lose LVM snapshots with ZFS, so no live backups for containers. I've also been trying to figure out the best configuration, decided to go with: 1. Upgraded memory - adding another 8GB for ZFS purposes. 2. 250GB SSD for OpenVZ containers using LVM. 3. 4 x 1TB regular HDDs...

That's fine, I won't be using NFS as it will be directly on the SSD. So then to sum everything up (for the sake of anyone else searching this topic): 1. TRIM works on LVM. 2. On VMs disk type must be SCSI and SCSI type (under options) must be set to virtio. Then make sure TRIM is enabled on...

Actually one more question. From the guest OS perspective I understand that for KVM I'll have to enable it per OS (for example our Windows Server 2008 R2 VM), do I have to do the same on containers or does that fall to the host OS to do?

Ah, excellent. Thanks I got it now.

Great, thanks. How do I use a virtio-scsi controller? I see I can set up a VIRTIO interface when adding a new disk, is there a driver I must enable on the guest OS?

I've been searching for information on using SSDs in virtual environments and there is a serious lack of clear information anywhere online. I just need some advice on if this is something that I should consider. Our setup is very basic, I just have a single node currently with 1 boot drive...

Here are command line manuals for VMs and containers: OpenVZ: https://pve.proxmox.com/wiki/Vzctl_manual KVM: https://pve.proxmox.com/wiki/Manual:_qm Maybe something in there can help.

I'm trying to decide which is a better option performance-wise but getting some unreliable results when using NFS. The storage server is running OpenMediaVault with a 4 disk Raid10 array. It's connected via gigabit ethernet on the same switch as the Proxmox node. For my NFS share I created a...

Many thanks for explaining so clearly. Will bring the second node up. Sent from my GT-I9100 using Tapatalk

Yesterday I completed my backups then set up a new node (was only using one node up till then). Now when I try to live backup my KVM VM I get these errors: INFO: starting new backup job: vzdump 108 --remove 0 --mode snapshot --compress lzo --node proxmox0 --storage backups INFO: Starting...

Just to update this thread. So it was the disk going bad, everything started to slow down on our Windows guest so went to investigate and found that the disk could no longer reallocate sectors due to the amount of bad sectors on the disk. Data was still readable so did a few mysqldumps of our...

Will try that and see what happens. Thanks Sent from my GT-I9100 using Tapatalk

I'm trying to figure out why vzdump is failing on one of my CT's. It was working fine for a few weeks and now suddenly it just fails after taking almost 2 hours to finish. Here is the log: INFO: starting new backup job: vzdump 100 --remove 0 --mode snapshot --compress lzo --storage disk2...

Thank you for the explanation, it makes sense now. So I should be good with 16GB free then. The first backup that I did contains a folder with thousands of small files, I'm thinking this may be the reason it is so much slower than the other CT. Thanks again for laying this out to a noob :D

Hi, I'm busy deploying a few containers to a Proxmox machine and I am busy configuring live backups, I've scoured the forums and everything is working so far but one thing I'm still unsure about it the amount of free space that is required on the volume group. Must the free space be equivalent...
