[linux-lvm] LVM cache "Manual Repair Required"

[Matt Joyce]

I am having some issues with the cache on my LV preventing the LV from
activating correctly usually some time on google gives me answers to the
problem but this time I am having no luck everything I try results in the
same "Manual repair required!" error.

$ sudo lvchange -ay hdd-vg/data-lv
  Check of pool hdd-vg/data-lv_cache failed (status:1). Manual repair
required!

$ sudo lvconvert --repair hdd-vg/data-lv
  Can't repair LV "data-lv" of segtype cache.

$ sudo lvconvert --repair hdd-vg/data-lv_cache
  Internal error: pool_is_active called with non-pool LV data-lv_cache.
bad checksum in superblock
  Repair of thin metadata volume of thin pool hdd-vg/data-lv_cache failed
(status:1). Manual repair required!

$ sudo lvremove hdd-vg/data-lv_cache
Do you really want to remove and DISCARD logical volume data-lv_cache?
[y/n]: y
  Check of pool hdd-vg/data-lv_cache failed (status:1). Manual repair
required!
  Failed to active cache locally hdd-vg/data-lv.

I have even tried resorting to removing the entire origin LV and even the
VG since the data on it is completely replaceable but nothing works due to
the manual repair required error I am at a loss what else to try here.
