Is this a regression (maybe related to 25bed9968155f43ef0b8832383ef711e7ae1685d)? Also, I assume that lvm can talk to clvmd as usual... (what I find suspicious is that we have a regression test for clvmd -R, so we should have noticed if it broke). I'll have a closer look. The problem is, as far as I can tell, that f5d39ec97aed3a77b5d0dfcd954dd78547e5748d needs to be backported to the RHEL5 package of 2.02.88 -- presumably 63b8ed7c37d166efd6f7e24bad8f64a2bc3239ef went in but that breaks clvmd -R without f5d39ec... in exactly the manner seen on 5.10.z packages. Marking VERIFIED based on Comment 9 and test with lvm2-2.02.88-12.el5 as well [root@virt-066 ~]# clvmd -R [root@virt-066 ~]# rpm -q lvm2 lvm2-2.02.88-12.el5 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
