KVM Migration storage slowly
Hello everyone!
I am using cloudstack 4.9.2.0 with 5 KVM hosts, however I have problem with
the migration of disks between storages they are limited to 300MBs in a
10GB network I already checked the network with iperf and I get 10Gb as
well as the IOs of the disks. But the copies really are limited to 300MBs,
has anyone ever been through this?

Hey SImon Hey Rafael,
Thanks for atenttion!
I solved my problem
It was in the HP controller that the write and read cache was disabled.
But I also noticed that my secondary storage for being gluster has a
considerable loss of speed.
I reinstalled my primary storage and I am preparing another glusterless
environment for secondary storage since I realized that migrating secondary
storage is not easy
Thank you all!
Sorry my English please :)

Rubens,
Also, you mention MBs (MegaBytes per second) and then reference 10GB in regards to network speed (which is really 10Gb, 10 Gigabits per second). 300MBs is about 2.4Gbs.
What type of primary storage are you using?
- Si

Hey Rubens,
This goes without saying, so excuse me if you have already checked these
parameters... did you check the network parameters? I think there is one or
two that are used to control this kind of operation.

Hey Rubens,
This goes without saying, so excuse me if you have already checked these
parameters... did you check the network parameters? I think there is one or
two that are used to control this kind of operation.
