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.
What is the output of `lsblk`?

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/sdb1 other, vfat, mounted on /boot/efi
/dev/sdb2 other, linux_raid_member
/dev/sdb3 ceph data, active, cluster ceph, osd.1,
block.db /dev/sdc3,
block.wal /dev/sdc4
/dev/sdc :
/dev/sdc1 ceph block.db, for /dev/sda3
/dev/sdc2 ceph block.wal, for /dev/sda3
/dev/sdc3 ceph block.db, for /dev/sdb3
/dev/sdc4 ceph block.wal, 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!
