Alasdair> Have you tried '--manglename none' if you aren't using a Alasdair> udev system that mangles names? (Also available via Alasdair> environmnet variable - see man page.) That seems to be working, using the default Debbian Jessie lvm tools: dmsetup --manglename none status --target cache data-home: 0 1153433600 cache 8 2443/32768 128 54020/819200 80721 350897 64427 66938 0 23882 1 1 writeback 2 migration_threshold 2048 smq 0 rw - data-local: 0 702545920 cache 8 2443/32768 128 1078/819200 6268 85795 1492 2715 0 1057 0 1 writeback 2 migration_threshold 2048 smq 0 rw - So now I can try to monitor my cache usage. So the question still remains, what is the long term fix so I don't have to deal with this breakage by default? Do I have bad UUIDS on my volumes?
