Subject: [linux-lvm] Removing lvmcache fails
Date: Mon, 21 Sep 2020 10:51:49 +0200 (CEST) [thread overview]
Message-ID: <552451034.4238344.1600678309529.JavaMail.zimbra@karlsbakk.net> (raw)
Hi all
I have an ssd hooked up to my system to do some caching of the raid-6 array. Now, that SSD isn't very new and has started developing some smart errors, so I thought I'd just remove it and find a nice recycle bin for it. However, this fails.
This is Debian Buster (latest) with kernel 5.4 and lvm 2.03.02(2)
Any idea how to get rid of this?
