[Linux-cluster] CLVMD without GFS

[brem belguebli]

Hi Rafael,
Of course, that is what I was telling you the other day, your script works
fine, but I just wanted to twist a little clvm.
The prerequisites are already setup (locking type, dm-mp, lvm, etc...).
The only thing that disturbes me is that you can bypass under certain
conditions the locking.
Thanks for the help
Brem
