i have 5 rotative disk 1TB RPM + 1 256Gb SSD i would use the five disks with a raid5 or similar for data with protection and the ssd for cache how can i realize this?

I think the SSD as cache drive is the problem. I don´t know if it is supported by OMV to use a SSD as disk cache for a RAID array. As I know mdadm does not support this. Also snapraid and mergerfs do not handle a cache disk.

@all: Please correct me if I´m wrong.

ZFS supports cache drives for several purposes. But this would mean a lot of manual work by CLI commands in OMV. But should be possible in principle.

It therefore depends which kind of RAID do you intend to use.

assuming i would use 4+2 raid 6 with 6 * 1TB disk and one 256GB ssd, shoud i use bcache? lvmcache or zfs?

i have seen some zfs example and it seems fine for my tests
