Description:

New bug from https://bugs.archlinux.org/task/40754 for LVM version 2.02.108.

LVM supports the cache target (e.g. for speeding up access via an SSD). This is documented in the lvm man page under 'Cache', as well as individual man pages such as 'lvconvert'. This feature isn't enabled in the current build.

To include it, simply add '-with-cache=internal' to the configure options in the PKGBUILD.

LVM version: 2.02.108

Steps to reproduce:

Attempt to create a cache pool, e.g.:

[root@arch ~]# lvconvert --type cache-pool --poolmetadata /dev/vg0/CacheMetaLV /dev/vg0/CacheDataLV
WARNING: Unrecognised segment type cache-pool

After the cache option is supplied:

[root@arch ~]# lvconvert --type cache-pool --poolmetadata /dev/vg0/CacheMetaLV /dev/vg0/CacheDataLV
Logical volume "lvol0" created
Converted vg0/CacheDataLV to cache pool.
