Hi Jakub,
I assume the solution you are searching for is something GlusterFS can serve for example: http://www.gluster.org/about/
Best, Sven.

I would be surprised if you could do that without your users noticing.
It seems like you would be better served to have each storage domain on a RAID array and rely on the hardware tools of the RAID to handle disk failure tolerance.
Cheers, jonathan

Hi,
would it be possible in near future to use for example 2 attached DATA storage (iSCSi, or so) as fault tolerant storage?
I mean I have two data storage connected to data center and they include exactly same data and my VMs runs from one and all changes are mirrored to second like RAID 1 and if one storage fails everything switch to second storage without user notice? _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

thank you for replies. Sven: I know Gluster. I am using it since 2009 in production but the problem is that many organisations and users already have Storage arrays (SAN,NAS,..) and migrating to Gluster is not possible or reliable. While I have 2 storage arrays I would like to use them like network raid 1. Also the combination of more storage types would be super cool (NFS + ISCSI) or so. Jonathan: Yes, I can rely on disk arrays for hdd fault tolerance, but there are more points of failure than disks (network, ram, cpu, water in rack and so). To be clear, I know, I can manage fault tolerance by hardware, but it is more expensive
