PVE can replicate VMs between local storages of cluster nodes. PVE1 can replicate VM 1's config and disk every 1min to x hours from PVE 1's XFS storage to PVE 2's XFS storage. That way if PVE1 fails, PVE2 will restart VM1 as if it was an accidental reboot. Downtime is as slow as your XFS is for...

I mean... PVE will host a CEPH cluster soooo... My dream is that they integrate OCFS2 so that when each node connects to an ISCSI volume you can add OCFS2 in the GUI to make it a shared volume with multipathing and LVM-Thin. Or any file or block system on top even except ZFS of course...

Thanks for your work in this thread and for all the support everyone here contributed, this was incredibly interesting and informative to read you guys! Has this been documented in the wiki by chance? Might be helpful as a troubleshooting section.

The replication (PVE based asynchronous) will take place over VPLS links separate from the leased fibre cluster links but those are very good estimates for storage iops per latency. Unfortunately, our VPLS links are currently 8-13ms (62.5 iops by your estimate) we are planning to reduce core...

Hi Spirit, Having a witness node in another DC is a good idea. That being said, the latency on the fibre will be 3.8ms (1ms per 100KM) given it would be clear of all other traffic. The recommendation in the wiki is around 5ms and below 10ms so if we can make it work then I will be happy. We...

Hey Thomas, Similar question to MSCD: We're looking at the future viability of using DarkFibre to connect an 8 node cluster across two cities (~378KM). We have calculated that the latency should be low enough and we will have authority over the fibre link with the exception that some points...

Very well said, Thomas. You taught me something today too! I've never witnessed this before: systemctl enable --now pvebanner.path Very neat. Also, I recommend the /etc/update-motd.d/###-script-name methodology of displaying dynamic login text. I do this for system load and health (sensors...

We ended up going with FlexVDI but I have left that job in the summer for my wedding. Working for a new organization that does not need VDI. Cheers, Tmanok

I am still interested in determining how to add an existing LXC root disk to a new LXC. It seems like a rather odd limitation that you can't recreate an LXC using its root disk, there must be a way that I've simply missed in my search online. Thanks, Tmanok

Update for everyone: I solved it by copying the virtual disk file for the VM as briefly summarized in the first option. It looked like this: Server A contains virtual disk in /mnt/sdb1/images/115/ Server B contains no virtual disk files but own the configuration. Create a mount point...

Hi everyone, I have a fairly simple problem. Power to some personal PVE servers was lost and when it came back one of my LXC's configured for HA was "migrated" and attempted to boot but failed to... I took a look to find out what happened and noticed that it was on local storage of the first...

This sounds like it could be one of the VM's but you'd have to pin it down. Also, those Samsung QLC SSDs are likely to wear out as a consumer disk. If you go to Datacentre>Node>Disks you will see the wearout percentage for each SSD if the SSDs are not obscured behind a RAID controller. If...

Bonjour! I know your problem has been solved, but just to save you time in the future... You tried both Hyper-V > Export to VHD and then later Starwind P2V + qemu-img convert. Well, both should work fine, I generally export from Hyper-V, but the step that will save you time is: qm importdisk...

Hi BBGeek, Not only is that a lot of manual overhead, but if there is no integration with PVE, then there is no live migration or backup... This is not an acceptable solution unfortunately. Thank you for confirming my understanding, that is really too bad that PVE has not developed a solution...

Oh well that's a dealbreaker anyway. MPIO is lower latency, higher throughput, and parallel, whereas LAGs do not present themselves to the iSCSI protocol as something with multiple paths just more bandwidth. Unfortunately that means that iSCSI cannot take advantage of the same physical links...

Hi Everyone, Sorry to bump an old thread. Can someone explain technically why LXC can't live on ZFS over iSCSI? Just as I was looking into this again I found this thread which is the first news I've heard about LXC not being supported on ZFS over iSCSI. Thanks, Tmanok

Hi Everyone, One of my major clients is considering PVE but I've run into the same snag as earlier this year. The organization has several HPE Nimble SANs and they aren't going away as far as I can tell. HPE Nimble is block storage only, so iSCSI is basically the one and only solution...

Thanks BBGeek, that's exactly what I needed to hear! Tmanok

Good evening, I believe so, and this forum post includes good ideas for alternatives too. But to your point, "Restore files" should also allow you to download an entire virtual disk. For containers this would be a root.pxar.didix I believe. Login to PBS > Datastore > datastore-name > CT >...
