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!
