btrfs: failed to read chunk tree on vde1 (f18 anaconda crash)
Hi,
I reported a bug to anaconda (rhbz 901905), but it might be btfs related.
Anaconda does this:

I booted again and did both the mk.btrfs and the mount manually and i

Is it a known issue?
Thanks in advance.

Re: btrfs: failed to read chunk tree on vde1 (f18 anaconda crash)
Thanks for asking, but in the end it was not btrfs related at all. Virt-Manager failed to issue a warning (for yet unknown reasons) and a single hard disk image was being accessed as two different devices... I spent quite a bit of time until i found it. (normally, virt-manager prevents this) Cheers.
