Hi,

in the "Physical Disk List" our disks are shown as 3TB Disks. We bought them as 4TB(I know its marketing) and they are shown by fsdisk as 3.6TB as shown below:

root@ceph-node-mru-3:~# fdisk -l /dev/sdb
Disk /dev/sdb: 3.7 TiB, 4000787030016 bytes, 7814037168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 3D3A6050-5CF0-4399-9E5A-AC5D3CB0E140

Device        Start        End    Sectors  Size Type
/dev/sdb1  10487808 7814037134 7803549327  3.6T Ceph OSD
/dev/sdb2      2048   10487807   10485760    5G Ceph Journal

Partition table entries are not in disk order.

 

Regards,

Dennis

Thanks for reporting this. It looks like we ignore the fractions.
