snapshot which is not really important.

Hi,
first sorry i got this totally wrong. The speed is not correct and i
mixed this with another operation going on at the same time.
The problem isn't the rbd export in my case it the fstrim issued on all VMs.
This results in writes up to 400Mb/s per OSD and then results in aborted

Sounds like maybe the client trim is ending up issuing a truly
