I'm a little confused. On their website it looks like they are trying to work with everything virtualization wise. Ultimately virtualization is the only direction that makes sense in their business model and unlike redhat they have no vertical integration. Gluster/Ceph are both redhat now and...

I've seen a lot of ceph performance issues reported so I've been steering clear of it, are there any other good options?

Hey All, I'm in a great environment right now: 2 x Openfiler NFS backend with DRBD 3 x Proxmox 3.x Hosts with about 20 VMs (all KVM) The systems are all on 10G networking, the backend storage is 24 disk arrays (spinning) with 4GB RAID cards and replication dedicated 10G cards. Anyway, we...

We use Idera with exceptional success. We install it offsite on a web host or provide a hosted option to our clients depending. Never had a problem with restoration on proxmox or vsphere

Just wanted to let ya'll know this issue was solved. I replaced the unit 3 times, the third time it worked. Interestingly the hardware was just unstable under load, but in a not re-producible way. We replaced: Battery Backup Power Supply RAM CPUs and finally the entire barebones unit 3 times...

FastLaneJB: In this description you're having no issues. It's a great little home setup, but again it's not 255.255.0.0, no advanced network configs or vlans (one assumes) In his original description and question he specified this netmask, if you're looking at a /24 netmask it's not even the...

I don't have any specific examples of vlan and advanced routing issues you might have, but I suspect you will see issues with advanced routing that may create some abnormal behavior like drops in connectivity randomly due to subnet mask lookups due to the switch (most cheap switches have a very...

Hey Ya'll I'm spotting a lot of NUMA errors on a windows server 2012 (in KVM as QCOW2 on PVE). Errors are like such: PerfOS: 2017: Unable to collect NUMA physical memory utilization data. My thought process is that none of the other VMs have this behavior, but it's pretty cryptic. Since...

Short answer: Container virtualization does technically work on NFS. Long answer: NFS Spews little files all over the container, these cause problems for applications where the software tries to manage the files in it's folders. An example of a program that fails to work in a container is...

I like what you're thinking. I actually recall hearing of such UPS issues though this would be the first time I've ever experienced it. I am using a pretty budget oriented UPS on that server. Potentially if the UPS is putting out improper power the redundant power supplies might shutoff to...

yes, if you don't use 255.255.0.0 and instead use 255.255.255.0 for your mask it should be much better, and for such a small test it would be no problem since you would need no special routing. if you must have more than 250 devices on the network then I'd wager you'll hit some odd problems...

No shortage of spare parts, just a shortage of time. this is the first I could get back to this issue since it isn't a client related issue ;D

Ok so, I've replaced the server (twice actually), updated the bios, replaced the hard drive (single ssd, not fresh install), replaced the 10G NIC, memtested till I can memtest no more (not in the listed order naturally) but basically I've narrowed this down to the server itself rebooting (and...

I haven't experienced this problem before and I use virtio almost exclusively. What does your network configuration look like? bonds? 100mb?1gb?10gb? Number of NICs? NIC model? If you believe it is the virtio under load crashing there are alternatives to using virtio as the type of virtual...

My personal experience with the backup features of proxmox (including the snapshotting) is that they are a poor substitute for a real granular backup. I have relied on them at times and had success, but the over all performance of that backup method and storage space used has consistently left...

We've used the WD raptor/velociraptor for a log time. In my experience it comes down to activity vs capacity. Under low activity and low queue depth the SATA usually outperforms the SAS. I would suspect this is because any enterprise SATA drives these days have 32-64mb of cache per drive...

I don't see if you are unmounting first. But my experience was exactly as you describe. Since iscsi acts as a local mount point it may need to be dismounted prior to disconnecting the session, for data sanity at least it should be. This might help clarify what I am trying to express more...

From a technical standpoint I could see it working, though of course not feasible in a production environment. The configuration would be something like this: Cable Modem (gateway) -> Switch -> ProxmoxVE Then install a VM with something, lets say pfsense, with a few virtual nics, then it...

I should clarify, you can do live migration of the VM (depending on file type, e.g. vmdk, qcow2, etc) however this does not move the storage location with a VM. Shared storage, in terms of best practices, is a storage location that is not also running a VM Host node for this reason.

In the past I've used a backup and restore because it is the mistake proof way. There is no live migration of running VMs on share storage that I know of. This can be done on containers however. It would depend on where you mount your container storage of course. Hopefully this is helpful...
