The output of `sudo df -h` would also be helpful. Sudo/root is generally required because the OSD folders are only readable by the Ceph user.

        Dear cephers,

        Could someone show me an url where can I found how ceph
        calculate the
        available space?

        I've installed a small ceph (Kraken) environment with
        bluestore OSDs.
        The servers contains 2 disks and 1 ssd. The disk 1. part is
        UEFI (~500
        MB), 2. raid (~50GB), 3. ceph disk (450-950MB). 1 server with
        2 500 GB
        HDDs, 2 with 1 TB HDDs total 3 servers.

        For example the HDD parts:
        /dev/sdb1      2048     976895     974848   476M EFI System
        /dev/sdb2    976896   98633727   97656832  46,6G Linux RAID
        /dev/sdb3  98633728 1953525134 1854891407 884,5G Ceph OSD
        info from ceph-disk:
          /dev/sda :
          /dev/sda1 other, vfat
          /dev/sda2 other, linux_raid_member
          /dev/sda3 ceph data, active, cluster ceph, osd.4, block.db
        /dev/sdc1,
        block.wal /dev/sdc2
        /dev/sdb :

        /dev/sdc3,
        block.wal /dev/sdc4
        /dev/sdc :

          /dev/sdc2 ceph block.wal, for /dev/sda3
          /dev/sdc3 ceph block.db, for /dev/sdb3

        ~ 30GB each 10 percent of the smallest real size. 3x
        replication. Could
        be possible that the system using wrong partition (2. in this
        scenario)
        for usable space calculation? Can I write more data than the
        calculated?

        Another hint?

        Thank you!
