Fixing a cache pool

# This happens because I was trying to restart the server but the windows vm does not listen to the KVM. So I forced a restart. Hence this error.
vgchange -ay

  /usr/sbin/cache_check: execvp failed: No such file or directory
  Check of pool GuestVM/lv8-cache failed (status:2). Manual repair required!
  13 logical volume(s) in volume group "GuestVM" now active
  0 logical volume(s) in volume group "Buffer" now active

# We'll have to reset the cache an re-attach it again
lvconvert --splitcache GuestVM/lv8-cache
lvconvert --type cache --cachepool GuestVM/lv8-cache GuestVM/lv8-win10-build
