Hello

Is anyone using OCFS2 on a SAN based setup (in my case iSCSI) for a
shared storage setup for KVM?

I've got a really nice setup that works really well and gives very
good performance.

However, the QEMU disk images (raw format) keep corrupting.

Is OCFS2 to be avoided in the setup or are there any workarounds? For
example filesystem setup.

Thanks

What version of KVM?  What command line are you using?

I've had no trouble using GFS2. Are you setting cache=off?

Shouldn't the caches on GFS/OCFS be coherent?

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
