There is a rbytes mount option [1]. Besides, you can use “getfattr -n ceph.dir.rbytes /path/in/cephfs” [1]: https://docs.ceph.com/en/latest/man/8/mount.ceph/#advanced Weiwen Hu 在 2021年11月17日,10:26,zxcs <zhuxiongcs@xxxxxxx> 写道: Hi, I want to list cephfs directory size on ubuntu 20.04, but when I use ls -alh [directory] ,it shows the number of files and directorys under this directory(it only count number not size) , i remember when i use ls -alh [directory] on ubuntu 16.04, it will shows the size of this directory (include it sub directory). i know du -sh can list the directory size, but it very slow as our ceph directory has tons of small files. Would anyone please help to shed some light here? Thanks a ton!
