Thanks for your response. When I create a new pv and test it with pvscan --cache the response on the primary node is: Found duplicate PV Trs11CMat90PaBJ2lm4YpzEKVXnDtx0P: using /dev/drbd0 not /dev/cciss/c0d0p4 Using duplicate PV /dev/drbd0 from subsystem DRBD, ignoring /dev/cciss/c0d0p4 Erasing this new pv returns nothing on the same node. In lvm.conf I've set write_cache_state = 0 so I'm wondering why lvm use a cache. This configuration is used in a openSuSE 42.1 on both nodes. _______________________________________________ drbd-user mailing list drbd-user at lists.linbit.com http://lists.linbit.com/mailman/listinfo/drbd-user
