Hi
[ceph: root@ceph-flash1 /]# rbd info rbd_ec/projects
rbd image 'projects':
size 750 TiB in 196608000 objects
order 22 (4 MiB objects)
snapshot_count: 0
id: 15a979db61dda7
data_pool: rbd_ec_data
block_name_prefix: rbd_data.10.15a979db61dda7
format: 2

deep-flatten, data-pool

We wanted to resize it to 1PB but that failed:
[ceph: root@ceph-flash1 /]# rbd resize rbd_ec/projects --size 1024T
Resizing image: 0% complete...failed.
rbd: shrinking an image is only allowed with the --allow-shrink flag
2024-08-06T08:42:01.053+0000 7fc996492580 -1 librbd::Operations: New
size not compatible with object map
We can do 800T though:
[ceph: root@ceph-flash1 /]# rbd resize rbd_ec/projects --size 800T
Resizing image: 100% complete...done.
A problem with the --1024T notation? Or we hitting some sort of size
limit for RBD?
Mvh.
