Subject: Thinp: how to enable discards?
Date: Fri, 15 Jun 2012 16:47:11 +0200 [thread overview]
Message-ID: <4FDB4AEF.9090004@shiftmail.org> (raw)
Hello all
I have booted a kernel 3.4.2 and compiled latest LVM2 tools.
I have created a thin pool and a thin LV.
in dmesg it says:
[72244.278644] device-mapper: thin: Discard unsupported by data device
(dm-1): Disabling discard passdown.
and in fact I cannot discard data on that volume. Not only the passdown
doesn't work, but the unmapping doesn't work either.
How can I enable this?
Thank you
S.
