Subject: [gentoo-user] OT: btrfs and qemu
Date: Thu, 08 Nov 2012 08:12:02 +0800 [thread overview]
Message-ID: <1352333522.14577.7.camel@moriah> (raw)
I am testing a small ceph cluster implemented in qemu-kvm and seeing
there are a few cloudy types here who may have tried this, I though I'd
ask about my problem before reworking.
I decided to go btrfs in the VM's and the ceph storage (all qcow2) on a
reiserfs host fs.
So far so good, but I am getting btrfs problems - throws an error and
goes readonly -> oops/crash in btrfs
I am now using cache=none for qemu (which is recommended for vm's on a
btrfs host, though not the case here) and that helped some.
My question is ... are there any other settings to help this
configurations stability/reliability using in vm btrfs?
Otherwise I'll go back to reiserfs for the hosts and try xfs for the
ceph storage.
