Perhaps it will help future sysadmins will learn from my mistake. I also saw very poor upload speeds (~30MB/s) no matter what I tried. I went through the whole route with unix-sockets and whatnot.
But, in the end, it just turned out that the glusterfs itself was the bottleneck; abysmal performance for small block sizes. I found the list of suggested performance tweaks that RHEL suggests. In particular, it was the "network.remote-dio=on" setting that made all the difference. Almost 10x faster. https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.1/html/configuring_red_hat_enterprise_virtualization_with_red_hat_gluster_storage/chap-hosting_virtual_machine_images_on_red_hat_storage_volumes _______________________________________________ Users mailing list -- [email protected] To unsubscribe send an email to [email protected] Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/[email protected]/message/F657ZJ32EYON4X5FAE2BQAHDI4LV5D36/
