[lvm-devel] [PATCH 00/10] Fixes related to mirror repair in clustered environment

[Milan Broz]

These are patches I created when trying to reproduce fails with
recent mirror repair changes.

Because it touch the core cluster locking parts, I separated it
to several simple patches to review it separately.

Please review and comment it - it is curretnly test blocker for clustering.

(If there is better way how to fix described problems - please let me know,
I am quite desperate after debugging this code ;-)
