Hello everyone.

I notice that the bwlimit is not working at all.

I've already tried to SET bwlimit through API when cloning a template, and also through Proxmox GUI:

As a result, the traffic is still reaching 1 Gbps:

Hi,

so you're testing with cloning a template. Can you specify:
1. if this is a Container or a VM
2. on which storage the template is located (NFS, local LVM, ...)
3. and to which storage it is cloned to

What graph is this? It seems that it's only showing incoming traffic?

1 - It's a VM
2 - The template is located in an external GlusterFS storage
3 - It's being cloned from an external GlusterFS storage to a local ZFS dataset.

The graph belongs to the Proxmox interface, it is showing only incoming traffic because the outgoing traffic is low, and all the incoming traffic belongs to the template being cloned when I did the screenshot (which is using the entire Gigabit port).
 
Hello there guys,
i'm new so a lot of testing nowadays. According to the topic, please @t.lamprecht could You confirm how the migration bwlimit works. I have some test vmachine with local zfs storage disk. I set up cluster with 2 hosts so i test migration offline/online and other HA scenarios. I've made vlan on cluster bridge (corosync is on separated nic), put manually in datacenter.conf the line
bwlimit:default=20480,migration=20480,clone=20480,move=20480,restore=20480
so online migration works with appropriate limit, but offline (i think's it's as copydisk) is going w/o any limits. Is that normal situation or did i miss sth sir in configuration.

Btw (maybe i should start in new topic) when I set up HA (state:started) for test vmachine, i can't do online HA Migration (just offline works), there is info:
"found local, replicated disk 'zfs-test:vm-100-disk-0' (in current VM config)
2020-10-05 14:57:52 can't migrate local disk 'zfs-test:vm-100-disk-0': can't live migrate attached local disks without with-local-disks option"
When i delete HA entry, the migration works again. Shouold i take in minde sth additional in configuration?
