Am trying to troubleshoot an issue that has arisen during a DR test and admit from the outset that LVMs are not my forte.
We have a RHEL6 VM running on ESXi 5.1. We are using a LUN to LUN replication to allow us to use a system called SRM to recover our VMs. There is a 3TB Logical Volume on the VM with each "physical disk" having its own hard disk and LUN created. The test recovery process takes a snapshot of the LUNs at the recovery site allowing tests to be made etc and then any changes are dumped.
All other VMs have been brought up correctly but this VM is not playing ball. The error I am receiving is:
Couldn't find device with uuid B91AAR-........
Couldn't find device with uuid zcRrvn-........
This means the LVM is missing two physical volumes so will not mount. Running "fdisk -l" I can see the two devices /dev/sdb/ and /dev/sdc/ but their is not /dev/sdb1 or /dev/sdc1. I initially thought that this meant the partition info had been trashed but running the same command on its live counterpart yielded the same result (sdb and sdc do not have a partition that fdisk is aware of). Form my understanding this is not a requirement for LVMs, though is not considered best practice for sanitys sake.
I have tried to recreate the physical disk using a restorefile and pvcreate but that states it still cannot find the physical disk. I am a bit stumped as to what to try next to try and get this working and would be grateful of any guidance someone could throw my way.
