We agreed at the blocker review meeting this morning that "most
commonly-used filesystem types" was really pretty vague and
unsatisfactory. The specific case we were considering was LVM. In the
end we agreed that, really, at Beta stage, anaconda ought to be capable
of dealing with any filesystem / device type it offers (the 'device
types' are LVM, RAID and btrfs). If a type isn't working it needs to be
either fixed or suppressed (as we did for the last couple of oldui
releases with btrfs - we suppressed it from the list as it wasn't
working). The intent here isn't to cover every possible bizarre
permutation anyone can come up with (the Final criterion does do that),
but more that just simply creating a partition in a pretty normal,
everyday way with any of the options offered shouldn't cause the
installer to fall over and die. Please, anaconda folks, if you think
this is too optimistic and you think we should exclude specific types or
limit the criterion to a specific subset of types, yell.
Am I interpreting this correctly to mean that a beta can go out without
support for software RAID and/or LVM, as long as they are not offered in
the Anaconda interface? If so, uugh.
Well, that's a complex question. =)
As far as the release criteria would be concerned, yes. My thinking is
that it's ultimately not exactly QA's decision what filesystem / device
types anaconda ought to offer, which is sort of what we'd be doing by
specifying particular types in the criteria, and it gets a bit unwieldy
to specify every type we reckon is important or isn't.
So in theory, sure, anaconda could drop RAID out of the interface and
the proposed criterion would be satisfied. But that decision could be
challenged _on its own merits_ rather than via the blocker process.
I do see what you're saying though, like I said, I'm not sure I've got
everything right here. It would be good to know what more people think
about whether we should get into the business of specifying 'critical'
partition / device types in the criteria or not. anaconda folks reading?
To give a specific proposal here, which I find always focuses minds, we
could simply adjust the relevant line to read:
Creating and, optionally, encrypting partitions of any specified size
using all offered device and filesystem types. RAID-0, RAID-1, RAID-5
and LVM must be offered as device types, and ext4 must be offered as a
filesystem type
Tweak as desired, but you get the idea. That's how we could do it if we
do go down the road of ignoring my addiction to non-specificity and just
specifying particular types in the criteria. Of course, we'd have to
adjust it over time, like when btrfs becomes more commonly used than
RAID and LVM in the Glorious Future.
Please include raid 10.
