Subject: Bcache explodes when trying to attach
Date: Sat, 15 Oct 2011 13:43:44 +0800 [thread overview]
Message-ID: <4E991D90.1040008@fnarfbargle.com> (raw)
I'm trying bcache merged with linus' git head (-rc9). I suppose I should really try it with a
vanilla bcache-dev tree.
Anyway, I can register the cache and backing device but when I try and attach the cache set to the
backing device this happens :
Cache is /dev/sde. Backing device is /dev/md10 (4 disk RAID10)
