That would seem to be a problem, yet if it's a raid1 device, anaconda finds an already created LV and lets me use it, even though in a shell 'cat /proc/mdstat' shows no raid devices running, and pvscan, vgscan, lvscan see no pvs, vgs, or lvs. So the probing anaconda is doing seems to be separate from those tools - and I'm going to guess there may be a bug there when it comes to linear/concat raid during the scanning. Some regression is in order it looks like. The UI is confusing though, if you're expecting to manipulate either a VG or LV, in particular if you don't actually know what physical disks make up the VG. So what disks do I pick? Ahh, looks like I *must* pick all constituent physical disks. If I don't, then the Manual Partitioning window sees only a partition on the drive to be obliterated. It doesn't see the VG or LV.

Based on this older thread, it seems that this should be possible, but somehow the installer is being very literal seeing physical disks instead of anything LVM. http://lists.fedoraproject.org/pipermail/devel/2012-December/174949.html Chris Murphy -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

I find this particular change to be very frustrating because LVM-on-RAID -- in my experience -- is such a common configuration. Maybe this is because I still have systems tied to actual physical disks; I can see that maybe this would be less common for virtual systems (in which the host would presumablyu take care of things like fault tolerance). -- Lars Kellogg-Stedman -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

Let's see...I'd say that what the criterion really means - what it was written for - is 'you should be able to successfully create any sane layout the custom partitioning mode will let you create'. That's what 'offered' is about (at the time, btrfs support was available but only via a sekrit command line parameter, hence 'offered in a default installer configuration'). So I'd say that if custom part actually doesn't allow you to do what you're trying to do, that's okay. If it tries to do it, but blows up when you try, that would be a blocker candidate. The criterion wasn't really written to cover the case we're in now, where the installer is being rewritten and bits of functionality are being lost; it's more appropriate to a 'steady state' installer whose capabilities are fairly well defined. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

does final criteria #8 mean lvm-on-raid must be available?
I tried to make a mirrored /boot partition, and then a second mirrored partition with an LVM volume group on top of that (including / and /home partitions). The current UI doesn't offer this, although it was easy to do in the old one. I'm not exactly excited about holding things up further, but does this need an exception to final release criterion #8: "The installer must be able to create and install to any workable partition layout using any file system offered in a default installer configuration, LVM, software, hardware or BIOS RAID, or combination of the above." ? It seems like it does, but I think the wording is ambiguous. (What is workable? What does "offered" apply to?) Brian Lane notes that there's not enough time to re-add this feature: https://bugzilla.redhat.com/show_bug.cgi?id=63 Also, this is further complicated because LVM now has its own mirroring and RAID features which could be used instead of the software raid (I think this is what RHEL 6.3+ docs now recommend, in fact, but I'm not sure -- I'll definitely defer to the storage experts on this). -- Matthew Miller ☁☁☁ Fedora Cloud Architect ☁☁☁ -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
