Hi,
So I have my small test cluster with 2 OSD nodes. In each OSD node,
there is one disk (5 GB) and one cosd.
When I mount the FS on a client, I see it's 10 GB in total. Fine.
I copied a small set of multimedia files (135 MB) and that's all. So
why do I see the space used is getting higher and higher ?
root@client:/mnt/osd$ df -h .
Filesystem Size Used Avail Use% Mounted on
10.1.56.232:6789:/ 10G 5.2G 3.9G 57% /mnt/osd
and like 2 hours later :
root@client:/mnt/osd$ df -h .
Filesystem Size Used Avail Use% Mounted on
10.1.56.232:6789:/ 10G 6.8G 2.3G 76% /mnt/osd
I'm using btrfs to store the files and I made no creation/modification
of files; i just run some bench with "ceph osd tell [12] bench"
Does the bench create files and do note delete them ?
