GFS2 Filesystems - Change in WWNs fo the devices

Posted on

Hello,

During a Storage configuration change, our GFS2 Shared devices will come up, after a reboot, with different WWNs but no change on the data.

For ordinary Filesystems, a vgexport/vgimport would help to bring up the filesystems in clean matter. But in the case of GFS2, do we have similar mechanism or the Pacemaker HA will be able to bring it up, after the reboot, as long as the data is intact?”

Thanks for your help

Regards

MI
