Hi, I have a vm in bhyve. The virtual disk is a ssd zvol, and the zpool the zvol is on is composed of two ssds in a stripe. The ashift=12. The host OS is recent -current I usually start my vms with a bhyve variable for the disk like: -s 4,virtio-blk,/dev/zvol/ssd/vm2 \ The man page for bhyve says this: ### NVMe device backends ### • devpath[,maxq=#][,qsz=#][,ioslots=#][,sectsz=#][,ser=#][,eui64=#][,dsm=opt] How do I get this information? Like maxq qsg ioslots sectorz ser eui64 dsm The ssds are: nvme0: <Intel DC PC4500> nvme1: <DC P3700 SSD> The ssds are of different sizes and different nvme versions: nda0: nvme version 1.2 nda0: 3815447MB (7814037168 512 byte sectors) nda1: nvme version 1.0 nda1: 1907729MB (3907029168 512 byte sectors) thanks in advance for any tips/advice --
