Hi all,? I appreciate if anyone could let me know: 1) How to check CephFS block size (It seems to be 4 MB which is really high)? 2) How to change CephFS default block size? I had a look at the following link but it seems that no option is provided for specifying block size! https://ceph.com/docs/master/man/8/mount.ceph/#options Thanks,?
