I am having an issue in a Hosted Engine GlusterFS setup. I have 4 =
hosts in a cluster, with the Engined being hosted on the Cluster. This =
follows the pattern shown in the docs for a glusterized setup, except =
that I have 4 hosts. I have engine, data, iso and export storage =
domains all as glusterfs on a replica 3 glusterfs on the first 3 hosts. =
These gluster volumes are running on an SSD Hardware Raid 6, which is =
identical on all the hosts. All the hosts have a second Raid 6 Array =
with Physical Hard Drives and I have created a second data storage =
domain as a glusterfs across all 4 hosts as a stripe 2 replica 2 and =
have added it to the Data Center. However if I use this second Storage =
Domain as the boot disk for a VM, or as second disk for a VM that is =
already running, the VM will become non-responsive as soon as the VM =
starts using this disk. Happens during the OS install if the VM is =
using this storage domain for its boot disk, or if I try copying =
anything large to it when it is a second disk for a VM that has its boot =
drive on the Master Data Storage Domain. =20
If I mount the gluster volume that is this second storage domain on one =
of the hosts directly or any other machine on my local network, the =
gluster volume works fine. It is only when it is used as a storage =
domain (second data domain) on VMs in the cluster.
Once the vm becomes non-responsive it cannot be stopped, removed or =
destroyed without restarting the host machine that the VM is currently =
running on. The 4 hosts are connected via 10gig ethernet, so should =
not be a network issue.
Any ideas?
