Also, anyone currently running any cool lvm cache setups? or want to share their setups or lessons learned for me to incorporate into the video?
I shot a video ages ago… editing backlog… updating it with some of the new data/metadata features. One quirk I found was that with large metadata pools it could degrade performance e.g. nvme + hdd was always fine but 280gb optane + 1tb nvme would be slower than either individually… but a smaller cache for just metadata worked really well with optane like 50g or so for 1tb of flash (and I doubt it even used the full 50g)
