when changing VM hardware properties for example, i'm getting "Connection error 596: Connection timed out"
when starting a VM, i see kvm process and the VM is shown running in gui, but in tasks "start failed: command .... failed: got timeout" is shown
our backup storage (synology nas mounted via cifs) crashed last night during backup run.
some VMs have been stopped with io-error because of this (as they had been backed up when the crash happened), but unfortunately even with backup storage unmounted (umount -f...) i could not restart...
yes, and that is the culprit.
it's not such a big deal for me if backup slows down VM disk IO, but slowdown is even growing with the number of cluster nodes and there is nothing you can do against it (without slicing your backup jobs into groups).
i don't have the issue (at least i'm happy i was not hit yet), but as we currently move a larger env from xenserver to proxmox, i really want this getting resolved, as this is a real bummer for me. it makes me nervous. enterprise products should not have such bug. loosing disk partitions...
is there a way to limit backup parallelism/concurrency in a cluster?
i have 5 nodes and when they all have vzdump run in parallel, our nas is heavily saturated and each of the backup "threads" is running slow
let there be some "Status: IO-Error" for a VM, for example bacause of out-of-diskspace condition.
Where can i see more details about such errors, i searched a while but can find no logfile containing it.
I had some host where VMs got io errors from time to time and i would have found...
you need to use virtio-scsi-single to make iothread=1 to be effectively used at all. iothread=1 without virtio-scsi-single is meaningless (though it's possible to configure in the gui)
using virtio-scsi-single does not mean that you use a single virtual disk...
mhh, ok, some of them are installed, must have overseen that that while trying, i was assuming that there would be much more difference between pve-no-subscription and pvestest
i wanted to try latest webgui features like cross-cluster migration and such stuff, maybe my expectation is simply...
