Hi, I have just experienced some issues relating to a PV UUID's not matching up with the UUID on an EVA SAN presented LUN after a reboot. The resolution was to recreate the PV with the new UUID using the restorefile. I am currently diagnosing the issue and trying to figure out how the UUID on the SAN LUN gets generated and how it may have changed between reboots. I am using CentOS release 5.5 (Final) Linux 2.6.18-194.3.1.el5 #1 SMP Thu May 13 13:08:30 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux Any help would be greatly appreciated.
