I would like to change the cache mode of an existing lvm cache
volume.
From a kind soul on the linux-lvm list:
'change' of cachemode is 'lvchange' operation
So looks like the correct command for my example *should* be:
lvchange --cachemode writeback vg_raid10/lv_var
but...
Please use some more recent version of lvm2 ( > 2.02.155)
The newer the better...
So this won't work yet on F23, which has LVM 2.02.150.
Regards,
Raman
