Alfredo, Yes, I tried vgscan, and it didn't help. Nothing helped except reboot. Issue is not reproducible with software disk deletion with /sys/block/sdb/device/delete I think because in this case block subsystem correctly deletes block device structure and all it's users like lvm pv,vg. It is not always reproducible with disk detach/attach. Tomorrow I will more carefully look at this issue, reproduce it and provide all possible information. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
