Trying to enable SSD caching with dm-writecache instead of dm-cache without success:
Using dm-cache is unacceptable because there is too many random reads from pve/storage.
How can I enable writecache mode? It look like version of lvm is too old.
Code:
lvm> lvconvert --type writecache --cachevol unsafe-write-cache pve/storage
WARNING: Unrecognised segment type writecache
Invalid argument for --type: writecache
Error during parsing of command line.Using dm-cache is unacceptable because there is too many random reads from pve/storage.
