[linux-lvm] what todo with broken cachedev?

[Oliver Rath]

Hi list,

assuming a cached device mylv from /dev/sda1 with cachepool from
/dev/sdb1 (ssd i.e.):

If now the ssd crashes and the cachemode is "writethrough" i think,
there is no data loss for my lv's, right?

But then mylv runs without a cache device although the device is set in
metadata.

The command lvreduce cant remove the cache-attribut. vgreduce *could*
remove it, right? But only if there is no usage bei the cachepool-device
anymore.

Is there a solution for that?

Tfh!
