Re: [Users] Creation of preallocated disk with Gluster replication
Do you happen to notice what is consuming CPU?
When I check with top, glusterfs and glusterfsd are the only process who
use a significant amount of CPU. Load average is between 5 and 6, and I
don't have any started VM.
Since the same cluster
does both virtualization and storage, a GigE network might get
saturated very quickly. Is it possible to separate out the management
and data/gluster traffic in this setup?
Unfortunately, it's not possible. I only have two hosts, both for
virtualization and storage. Why does glusterfs use so much CPU ?
About the network traffic, the creation of a pre-allocated disk is not
something which absolutely needs to be fast : if it takes 5 minutes,
well... it takes 5 minutes. I guess that if there's a way to limit the
bandwidth available for glusterfs, it'll still have an impact on
production because glusterfs and VM will be in competition for
bandwidth, right ? Is there a way to limit the bandwidth only for the
creation of a pre-allocated disk ?
Thank you,
