Usually after an update/upgrade the browser cache (and maybe history) need to be cleaned/erased, or some bizarre behaviour shows up. Have you tried it?

Hi, prox 4.1 (enterprise), 3 node cluster with 2 node with drbd9 thin provisioned storage (package thin-provisioning-tools installed in both nodes). I've created a 400GB second disk on node1, and since is empty at the moment, I see "data% 0.05" with lvs. But if I go on the second node, I see...

Hi, I've prox 4.1 (enterprise repo) and drbd9 cluster with thin provisioning enabled. I've seen that if I create a VM in drbd9 storage is correctly thin provisioned, but if I restore the VM then 100% (almost) of the space is alloccated. i.e. I've backedup VM 108 and restored as VM 999, and lvs...

Don't know if it makes sense (I'm not a guru), but should be considered also "power loss data protection" that most DC drivers have and consumer grade don't. With that feature usually the driver has a sort of "embedded bbu" and returns to the OS a really fast "write done". I've seen it with ext4...

Coul you give me more details about your (suggested) supermicro setup for ZFS? What HBA do you use for ZFS (that needs NO "intelligent" controller on it's path to disks)? Thanks a lot

Never used or tried IPV6, but bridges are layer2 (think of it as it were a physical switch), so a bridge does not care at all about IPVx. In short, you can have whatever layer3 (and above) protocol you want on the same bridge at the same time, AFAIU.

If for "zfs storage" you mean that the disk is a volume (block device), you should now be able to "move" from GUI the virtual disk to the "ZFS Plugin type" storage (hardware -> disk -> move disk -> target storage)

He means something like: zfs create rpool/zfsdisks pvesm add zfspool zfsvols -pool rpool/zfsdisks -content images,rootdir -sparse then when you create a VM, choose "zfsvols" as storage. This way the disks of the vm will not be files on the file system, but volumes, so removing one layer of...

Just a shot in the dark... You could have driver issues, and packets are dropped because "malformed", try with a different ethernet nic (i.e. Intel chipset brand). Check also the cable (replace it) and try a direct connection with a PC so you can exclude switch issues or configurations. Have a...

Not what you are requesting, but a (different) solution could be a (K)ubuntu VM (on ssd storage or in any case fast I/O) with LTSP configured, and for performance the clients used as "fat client" (if they have a decent processor and >= 1.5 GB ram). Have a look at www.ltsp.org and ubuntu...

Is your writeback raid cache working for sure? Are you on ext4 and is mounted with barries (by default is on, it's safest but much slower)? Are you testing pveperf with NO VM running? With no vm running, iotop -o is showing some strange activity by some daemon? I've no more ideas left :)

While you are waiting for an answer by someone that has seen the problem and solve with R720xd, I would try to play with UEFI / CSM settings as well (just a shot in the dark).

Solved shutting down the VM and then removing snapshot. Is it normal or a bug?

Hi, I tested with a VM (qcow2 image file format) and took at snapshot at "stage 0" before trying to install paravirt (virtio) drivers, so disk was IDE and not, after snapshot, is Virtio. Since everything works fine and the snapshot is no more needed, I tried to delete it from GUI, but got the...

He was asking about restore, and I think that could be an interesting option to have. If you have a vm that takes a lot of time to restore and you need to have it run as soon as possible at the moment you have to check the process and be there ready to issue the start command when it finished...

Solved with drbdadm adjust all on node prox02

Have you tried to compare qm showcmd vmid output in both situations? Maybe is something "injected" on the fly in the runtime stat config of qemu

You have to leave the bios boot option in UEFI, otherwise will not boot, but I had another issue. I've had a look at my notes about the issue, and on Mitac Pluto I have to do the following: Before installation set UEFI as general setting with UEFI first or "UEFI only" for all the peripheral that...

Press F12 there and select the correct HD. If it boots, is just a matter to go to Options of the VM and select the right boot device, if it does seems that you have troubles in the HD of the VM, try to boot with systemrescuecd.iso and troubleshoot.

Try to enable UEFI (not secure boot) at bios level, and install this way. I have a similar problem with Mitac Pluto 220 that has 1900 too. Only drawback is that the image is very large, you need a wide full hd screen connected. If you don't see the buttons, remember that the first confirmation...
