Hi,
I thought about a self hosted engine setup using 2 hosts connected to
a iSCSI storage.
A few questions arose and I didn't succeed finding the answers on the
web. I somehow don't get how the iSCSI integration in ovirt works.
- As far as I understand from the information I found, all iSCSI
access for the virtual machines is done through one host. Does this
mean, that all disk related traffic of the other host is going to the
first host and then to the iSCSI storage?
- no, every host has a separate access to the storage, only the storage
setup is done by a single host and then it's available for everyone.
In this case. How are the
virtual disk images then made available for the VMs on the other host?
- If the first host fails, the engine will get started on the other
host. Will the engine deal with the fact, that now the iSCSI storage
domain has to be accessed using the other host. Or is iSCSI just not
suitable for this kind of usage.
- Has the self hosted engine to use a different iSCSI lun than the
storage domain?
Thanks
Markus
