Maximum CephFS Filesystem Size
All; We set up a CephFS on a Nautilus (14.2.8) cluster in February, to hold backups. We finally have all the backups running, and are just waiting for the system reach steady-state. I'm concerned about usage numbers, in the Dashboard Capacity it shows the cluster as 37% used, while under Filesystems --> <FSName> --> Pools -_> <data> --> Usage, it shows 71% used. Does CephFS place a limit on the size of a CephFS? Is there a limit to how large a pool can be in Ceph? Where is the sizing discrepancy coming from, and do I need to address it? Thank you, Dominic L.

All; Another interesting piece of information: the host that mounts the CephFS shows it as 45% full. Thank you, Dominic L.

I have the same problem. 30TB available on Ceph, but my SMB share has only 5TB available. At IRC I was told I should raise pg count and run balancer. Raising pg count helped a little and I'm waiting Ceph to recover from pg resizing to run the balancer. -- Salsa Sent with ProtonMail Secure Email. ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Wednesday, April 1, 2020 12:43 PM, <DHilsbos@performair.com> wrote:
