It would appear as though the default is to not enable thin-provisioning, and the PKGBUILD does not have any inclusion of that option either. /tmp/makepkg/src/LVM2.2.02.98 $ ./configure --help ... --with-thin=TYPEthin provisioning support: internal/shared/none [[TYPE=none]] ... It appears as though you need to edit the PKGBUILD and build yourself. Regards, -- Curtis Shimamoto sugar.and.scru...@gmail.com

[arch-general] LVM Thin Provisioning
Hello, I have been reading about Thin Provisioning in LVM and wanted to play with it however, when I try to create a thin pool it shows an error saying: # lvcreate --thinpool -L 1G vg/pool WARNING: Unrecognised segment type thin Unable to create LV with unknown segment type thin. Run `lvcreate --help' for more information. I am running version: # lvm version LVM version: 2.02.98(2) (2012-10-15) Library version: 1.02.77 (2012-10-15) Driver version: 4.23.0 and have the following targets for device mapper: # dmsetup targets snapshot-merge v1.1.0 snapshot-origin v1.7.1 snapshot v1.10.0 zero v1.0.0 striped v1.5.0 linear v1.1.0 errorv1.0.1 According to what I could find, this feature has been available since version 2.02.89 and is enabled with the compile time option of --with-thin=internal, but doesn't appear to be enabled in the Arch package. Am I correct or does something need to be configured on my machine? Thank you Squall -- Yesterday is history. Tomorrow is a mystery. Today is a gift. That's why its called the present.
