We only recommend creating multiattach volumes by using a multiattach volume type and that is the only way. Thanks for pointing this out, looks like we need fixing in our documentation. - Rajat Dhasmana On Tue, May 9, 2023 at 9:54 PM Tony Liu <tonyliu0592 at hotmail.com<mailto:tonyliu0592 at hotmail.com>> wrote: Hi, [1] says "Currently you can create a multiattach volume in two ways." I see one way is with volume type. What's the another way? [1] https://docs.openstack.org/cinder/xena/admin/blockstorage-volume-multiattach.html Thanks! Tony
