I have a number of VMs with raw disk files on an NFS datastore. I created drbd mirror to other host in proxmox cluster. Put LVM on top of that with shared set to true. This way, as I understand it, each vm disk is an LVM. Anyway, all but two restored just fine (e.g. I did backup from NFS raw...

Odd. I rebooted the node whose VMs had no names and now it's all good.

Two nodes in a cluster. Took down the master to do some HW changes. Rebooted and they are both up, but the two VMs that run only on the 2nd host are not showing the names in the webUI, even though they do show if you look at their configs. I assume something is stale and/or needs to be...

I currently have two PVE2.3 hosts in a cluster. A 3rd host running Ubuntu/ZFS serves ISO/images to the hosts. The backup server (2nd proxmox) also runs a small storage appliance (also ubuntu/zfs) with two 1TB drives passed through to it. The main ubuntu sends snapshots every 5 minutes to the...

Ah, okay. That's a relief, thanks. I suppose that explains the warning about the partition not ending on a cylinder boundary...

So I did a VE 2.2 install and it's working just fine. I want to move the boot disk to a smaller SSD so I can use the larger one for other purposes. I happened to be looking at the output of fdisk, and something suspicious leaped out at me: root@proxmox:~# fdisk -l /dev/sde Disk /dev/sde...

Sounds like some kind of filesystem corruption :(

Keep in mind that in general, multiple IP NICs on the same subnet is bad, as outbound traffic will usually just take one path.

Well, I am mystified as to problems with ECC memory that cause serious slowdown with no crashes or errors other than something weird like that...

It isn't proxmox, it's the debian installer :)

boy that is weird! only thing i can think of is ecc ram was generating a lot of errors and system was working hard to correct them and slowing you down?

Not sure what exactly you tried. I have seen at least one case where the ubuntu installer (i know you don't run ubuntu, but maybe this is more common) installed to wrong HD by default. ex: I have 5 600GB drives for raid pool, and 80GB drive for OS. That one is /dev/sdf and I told installer to...

Only thing I can think of is the virtual NIC on the other setup was dropping and/or corrupting segments...

I seem to recall from other threads that the above does not work for windows xp, which is the case I care about :( I have had to train myself whenever ending a remote desktop session to my XP VM to logout from the VM so that if the host node needs to shutdown, it can.

Well, as always, there is a tradeoff. RAID1/10 do cost half your space, but I have to admit RAID10 performance is nice :)

Nice. My proxmox box is just a dual-core, but that is better than nothing maybe. I will have to try and see...

How must faster is 'drastic'?

I agree with you, mmenaz. There are times when fault tolerance for disks is not a concern. My proxmox box has one single PATA drive. I don't care if it dies, as I have vzdump backups of the VMs, and each VM is also backed up every night, so the most I can lose is 1 day of changes (which is...

On the guest, looking for IP dropped packets (none visible here) and tcp dropped segments. I note a lot of bad segments received. Can you capture this output, run a test where you see slow transfer to the guest, capture again, and compare the count of "bad segments received"? Might want to do...

Possibly dropped tcp segments and/or corrupted ones? What does 'netstat -s' on guest show?
