I'm sure many people have much better info on this - but back in the day, running XFS on LVM (on md?) on i686 was not a good idea due to issues running out of stack space. I don't know if this has changed in any way, or if arm is better in this regard. But that would be my concern. I think RHEL6 doesn't support xfs on i686, and RHEL7 has dropped i686 completely it seems. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA/CoRA Division FAX: 303-415-9702 3380 Mitchell Lane or...@cora.nwra.com Boulder, CO 80301 http://www.cora.nwra.com -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
