I'm looking at building several multi-TB arrays in an academic
research
environment. So far I've been heading toward FC3 (or possibly RHEL4 when
it's released), EVMS, and XFS.
I've seen little or no mention of EVMS in the Fedora and RHEL communities,
and
I'm wondering why that is. From reading websites & mailing list archives,
it seems to me like EVMS is more mature than LVM2, and more fully-featured
than
either LVM or LVM2. I've not actually used any of the three yet.
Today I'm patching the FC3t2 kernel (541) with the patches (mostly DM
patches) recommended on the EVMS website
http://evms.sourceforge.net/install/, and
it's going quite smoothly. So far only the first patchfile in the udm1
patchset didn't apply, because it's already applied in FC3t2 kernel 541.
A similar patching attempt yesterday on FC1 was miserable (I expect no one
will be surprised at that :).
Is there a good reason to use LVM or LVM2 rather than EVMS? Is there a
reason EVMS isn't included in FC?
IIRC LVM was accepted by kernel developers over EVMS, which quietly accepted
this decision.
