Anyone tried the posix backend for Ceph radosgw? Appreciate any pointers here on configuring and testing. Varada On Fri, Feb 14, 2025 at 12:40 PM Varada Kari <varada.kari@gmail.com> wrote:
Hi,
I am trying to test the posix backend for radosgw in my test machine. It is running Ubuntu 22.04 with the latest squid release(19.2.0) I have configured a small single node cluster without any osd.
$ sudo ceph -v ceph version 19.2.0 (16063ff2022298c9300e49a547a16ffda59baf13) squid (stable) $ sudo ceph -s cluster: id: 92d1770c-e83e-11ef-bcc9-5f5839c0a1fa health: HEALTH_WARN Failed to place 1 daemon(s) Reduced data availability: 1 pg inactive OSD count 0 < osd_pool_default_size 3

Test machine is running a raided xfs file system. Using the below config in the radosgw.conf
[client]
rgw backend store = dbstore rgw config store = dbstore dbstore db dir = /mnt/raidx/rgw/dbstore dbstore_config_uri = file:///mnt/raidx/dbstore/config.db
rgw filter = posix rgw posix base path = /mnt/raidx/posix/root rgw posix database root = /mnt/raidx/rgw/posix/lmdb
[client.radosgw.gateway] rgw init timeout = 1200 rgw frontends = beast port=80
Not able to start the radosgw, fails to initialize the rados.

My intent is to run a standalone radosgw with a filesystem backend, which works as a s3 gateway. It would be better if i can avoid running a ceph-mon and other daemons as it is just working as a s3 gateway. Are there any configuration steps I am missing here? Please point me to any documentation available on this. Would appreciate any help on this.
Best, Varada
