Hi,
pvcreate could fail due to multiple reasons, it could be a wrong "filter" in /etc/lvm/lvm.conf or due to a corrupt cache. Could you do the following and pass me the details.
1. Search for "filter" in /etc/lvm/lvm.conf, and see what is it set to.
2. Run a vgscan
3. Try creating the SR again.
4. If step 3 does not work, run vgscan again
5. iscsiadm -m node -T iqn.2013-07.example:shareddisk -p 192.168.1.2 -l => iscsi login and dev creation
3. Output of /etc/lvm/cache/.cache
Thanks,
Vineeth
