Re: [Linux-cluster] CLVM and AoE



Hey Jure,

We're already committed to the AoE route unfortunately, but we're setting up next week, and I'll keep everyone posted on any performance benchmarks we glean.

If you don't use GFS, just make absolutely sure that there is no way
that two nodes could mount the same lv.  As far as I know, there is
nothing in the cluster that will prevent an ext3 or xfs filesystem
from being mounted by multiple nodes.  And if it happens, you have
almost guaranteed data corruption.

If the underlying storage is scsi3, one can use persistent scsi reservations, which can be set with some tool from the sg3_utils package. In case of AoE, this is of course not possible.
