Pankaj, I think Linux will not allow bigger block size than page_size. If you want bigger block size than 4K, you need to rebuild the kernel I guess. Now, I am not sure if there is any internal settings (or grub param) to tweak this page size during reboot or not. I think it is recommended (or best practice ) to have bigger inode size and also inode64 mount option.

Is it recommended for Ceph to choose a bigger block size? I'd like to understand the impact of block size. Any recommendations?
