Or are there any other recommondations regarding striping? I'm a bit confused cause rbd info shows stripe-count as bytes? rbd image 'vm-113-disk-4': size 1024 GB in 262144 objects order 22 (4096 KB objects) block_name_prefix: rbd_data.d0f7639a214d format: 2 features: layering stripe unit: 128 KB stripe count: 8 bytes Stefan
