https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251828 Bug ID: 251828 Summary: "zfs create -o <mode>" ignores mode when creating the device node Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: asomers@FreeBSD.org zvols have a "volmode" property that controls how their device nodes are created: as geom devices (default), as non-geom character devices, or not at all. At least, it's supposed to do that. But on 13-CURRENT, the volmode property gets ignored at creation time. The device always gets created as the default type instead. The easiest way to demonstrate the problem is to use gpart on the device node. It isn't supposed to work if the node is a non-geom device. But it does! # zfs create -o volmode=dev -V 64m testpool/vol # gpart create -s gpt /dev/zvol/testpool/vol zvol/testpool/vol created However, if we change the volmode property after creation, then ZFS destroys and recreates the device node with the correct volmode. # zfs create -V 64m testpool/vol # zfs set volmode=dev testpool/vol # gpart create -s gpt /dev/zvol/testpool/vol gpart: arg0 'zvol/testpool/vol': Invalid argument -- You are receiving this mail because: You are the assignee for the bug.help
