true? (The keyring file was empty.)
Yes, your're right, I disable auth. It's just a personal cluster, so the simpler the better.This looks like a trim issue, but I don't remember what all we fixed since
.1.. that was a while ago! We certainly haven't seen anything like this
recently.
I pushed a branch wip-mon-skip-auth-cuttlefish that skips the missing
incrementals and will get your mon up, but you may lose some auth keys.
If auth is on, you'll need ot add them back again. If not, it may just
work with this.
You can grab the packages from
http://gitbuilder.ceph.com/ceph-deb-precise-x86_64-basic/ref/wip-mon-skip-auth-cuttlefish
or whatever the right dir is for your distro when they appear in about 15
minutes. Let me know if that resolves it.Thank you for your work, I will try as soon as possible.
PS: My distro is Gentoo, so maybe I should build from source directly.
