Hi all,
I have a question: can lvmcache be used to cache non-lvm source (ie: a raw
block device)?
From the lvmcache man page I would say no; however, a direct confirmation
will be helpful.
Hi
You can't use lvm2 on 'raw' device - we do require PV headers to stay correct.
BUT
Clearly you can use 'dm-cache' target with 'dmsetup' utility and maintain the
correctness of devices & activation yourself.
See: linux/Documentation/admin-guide/device-mapper/
(or simply google it) how to use individual targets with just dmsetup
Regard
