Subject: [linux-lvm] How to flush dirty cache with dm-cache?
Date: Sun, 1 Oct 2023 11:14:53 +0200 (GMT+02:00) [thread overview]
Message-ID: <b51c197.ba16e860.18aea84e80f@tnonline.net> (raw)
Hi,
Is it possible to force a flush of the dirty cache in a dm-cache device?
I read in the kernel docs[*] that there is a cleaner policy, but it doesn't describe well how to use it.
Ideally, I'd like to be able to use `dmsetup message` to issue a flush after suspending the cache to ensure that all dirty data is written to origin and no more data is dirtied before resuming. Is this possible?
Thanks
Forza
