If one was to attach a shared iSCSI LUN as 'storage' to an oVirt data =
centre that contains existing data - how does oVirt behave?
For example the LUN might be partitioned as LVM, then contain existing =
filesystems etc...
=20
- Would oVirt see that there is existing data on the LUN and simply =
attach it as any other linux initiator (client) world, or would it try =
to wipe the LUN clean and reinitialise it?
Context: Investigating migration from XenServer to oVirt (4.2.0)
All our iSCSI storage is currently attached to XenServer hosts, =
XenServer formats those raw LUNs with LVM and VMs are stored within =
them.
If the answer to this is already out there and I should have found it by =
searching, I apologise, please point me to the link and I'll RTFM.
