Hi,
we have a CephFS with a replicated data pool and an additional EC data pool. All files store their data in the EC pool.
But "ceph df" shows that the replicated data pool contains over 200 million objects with a total size of 700 bytes. So the vast majority are empty objects.
How can this be?
Hello, The replicated pool is the "default pool" and contains files metadata ? (unlike the "metadata" pool) Like in this filesystem with ~1.4 billion files and 85 million directories: POOL ID PGS STORED OBJECTS USED %USED MAX AVAIL cephfs_EC_data 3 8192 6.6 PiB 3.00G 8.3 PiB 79.90 1.7 PiB cephfs_metadata 4 256 778 GiB 84.70M 2.3 TiB 3.38 22 TiB cephfs_default 5 128 0 B 1.37G 0 B 0 22 TiB Loïc. -- | Loic Tortay <tortay@cc.in2p3.fr> - IN2P3 Computing Centre |
