The NVMe disks in snap-02 are using 512 sectors instead of 4096 byte sectors. The sector size should likely be changed if boosts performance.
LBA Format 0 : Metadata Size: 0 bytes - Data Size: 512 bytes - Relative Performance: 0 Best (in use) LBA Format 1 : Metadata Size: 0 bytes - Data Size: 4096 bytes - Relative Performance: 0 Best
Changing the disk sector size formats (deletes contents) the disk, the sector size needs to be carefully coordinated with mdadm.
Outline steps:
mdadm --fail
mdadm --remove
nvme format --lbaf=1
mdadm --add
(repeat disk by disk across all 9 disks)
