So I just rebuilt my LVM to just my SAS drives but I still ahve two enterprise grade 32Gb SSD's in the server and I saw a guide online saying LVM supports cache like so :

Create
The fast method is creating a PV (if necessary) on the fast disk and add it to the existing volume group:
# vgextend dataVG /dev/sdx

Create a cache pool with automatic meta data on sdb, and convert the existing logical volume (dataLV) to a cached volume, all in one step:
# lvcreate --type cache --cachemode writethrough -L 20G -n dataLV_cachepool dataVG/dataLV /dev/sdx

Question is, should I make use of my SSD's in this way on proxmox?
