Hi David, Sorry for faking this reply because I'm not in the maillist before I noticed this email (quoted blow) you posted for a while.
I have a questions about "lvmlockd": Besides clvmd cannot be used together with lvmetad, is there any other main differences between "lvmetad" and "clvmd"? Do you recommend we replace "clvmd" with "lvmetad"? Thanks for your brilliant efforts. I will have a try soon;-) Eric """ For people using LVM (or clvm) on shared storage, I encourage you to take a look at two recent additions that you may find to be an improvement: 1. System ID is for static ownership of VGs by hosts: http://man7.org/linux/man-pages/man7/lvmsystemid.7.html The nearest equivalent to system ID in the past has been configuring lvm.conf filters uniquely on each host. 2. lvmlockd is for dynamically sharing VGs among hosts: http://man7.org/linux/man-pages/man8/lvmlockd.8.html Using lvmlockd with dlm is similar to what clvmd has done in the past. Using lvmlockd with sanlock has no prior equivalent. (For distribution packaging, see the "lvm2-lockd" rpm.)
