[ovirt-users] Re: How does ovirt handle disks across multiple iscsi LUNs

Hi Peter, The question is somewhat unclear here. First of all, a storage domain on iSCSI maps 1:1 to a LUN. So 1 LUN = 1 Storage domain. The storage domain is configured with LVM and each VM disk is a Logical Volume. If the LUN/Storage domain goes out of space, then no new space can be allocated, but if you have thick provisioned VM disks, they could still be able to write to the disk.

Are these allocated one per LUN, so if e.g. a LUN runs out of space the disks on that LUN (only) will be unable to write? Or are these distributed across LUNs, so if a LUN fails due to storage failure etc the entire storage domain can be affected? > > Many thanks in advance, Peter > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/ZZMV3G6EYBM...
