Arch Linux

Description:
An attempt to create a thin-provisioned pool using LVM2 fails with the following message:

WARNING: Unrecognised segment type thin
Unable to create LV with unknown segment type thin.
Run `lvcreate --help' for more information.

I have loaded in dm_thin-pool module, but that did not help. After some research online and a review of the PKGBUILD file, it appears that a compile flag was not enabled for this package. Specifically, an additional option --with-thin=internal should be added to the ./configure command.


Additional info:
* package version(s)
core/lvm2: 2.02.98-3

* config and/or log files etc.
N/A

Steps to reproduce:
As per the description. Any attempt to create any type of thin-provisioned volume will fail with the message 'unknown segment type thin'. This appears to be due to the package not being compiled with support for thin provisioning.

As a (bit of an) aside/warning:
An attempt to manually compile the code for LVM failed on my machine. There appears to be a required package for thin-provisioning tools which I was unable to compile. I didn't try too hard, and this is almost certainly due to problems with my compile settings/flags. That being said, I mention this to point out that there may be some dependencies (I am unsure whether these are build or runtime dependencies) which would need to be addressed. At the least, it would be great if someone might be able to make an alternative package available via AUR for those who want the functionality (and don't mind the dependencies).
