If the question it's not clear here is a detailed explanation: I have created a gfs filesystem (the usual procedure) that has two paths to the same device (QLogic hba connected to an IBM SAN) Example: /dev/sdb is the same as /dev/sdc and my PV was created with /dev/sdc. Now I would like to create a multipath device with this devices (/dev/sdb and /dev/sdc) but I don't want to lose my data. Is that possible?
