Hi, Somehow this output always made me confused. Can you confirm my calculation is good here? I have this output: --- RAW STORAGE --- CLASS SIZE AVAIL USED RAW USED %RAW USED nvme 89 TiB 82 TiB 6.6 TiB 6.6 TiB 7.43 rbd 31 TiB 16 TiB 16 TiB 16 TiB 49.52 ssd 2.3 PiB 1.0 PiB 1.2 PiB 1.2 PiB 54.14 TOTAL 2.4 PiB 1.1 PiB 1.2 PiB 1.2 PiB 52.36 SSD: ec 4:2 rbd: repl 3 I want to know the stored data, which means the user side data. In ceph in EC 4:2 a 100MB object is stored on 150MB. In case of ssd, I want to know the used 1.2PiB means how much real user data? For me 1.2PiB used SSD means ~903TB user data on ec 4:2. In case of rbd, ~6TB. Am I correct? Ty ________________________________ This message is confidential and is for the sole use of the intended recipient(s).
