In testing, forcibly removing the cache, via editing the LVM config file has caused extensive XFS filesystem corruption, even when backing up the metadata first and restoring after the cache device is missing. Any advice on how to safely uncache the volume would be massively appreciated.
It is my understanding that a writethrough cache should *never* have any data that are not on the backing volumes already. In other words, forcibly removing a writethough cache (ie: disconnetting the physical cache device) should not cause any harms to filesystem/data.
Can you show the output of "dmsetup table"?
