Hi Friends,
We have some inconsistent storage space usage reporting. We used only 46TB with single copy but the space used on the pool is close to 128TB. Any idea where's the extra space is utilized and how to reclaim it? Ceph Version : 12.2.11 with XFS OSDs. We are planning to upgrade soon. # ceph df detail GLOBAL: SIZE AVAIL RAW USED %RAW USED OBJECTS 363TiB 131TiB 231TiB 63.83 43.80M POOLS: NAME ID QUOTA OBJECTS QUOTA BYTES USED %USED MAX AVAIL OBJECTS DIRTY READ WRITE RAW USED fcp 15 N/A N/A 23.6TiB 42.69 31.7TiB 3053801 3.05M 6.10GiB 12.6GiB 47.3TiB nfs 16 N/A N/A 128TiB 66.91 63.4TiB 33916181 33.92M 3.93GiB 4.73GiB 128TiB # df -h Filesystem Size Used Avail Use% Mounted on /dev/nbd0 200T 46T 155T 23% /vol/dir_research #ceph osd pool get nfs all size: 1 min_size: 1 crash_replay_interval: 0 pg_num: 128 pgp_num: 128 crush_rule: replicated_ruleset hashpspool: true nodelete: false nopgchange: false nosizechange: false write_fadvise_dontneed: false noscrub: false nodeep-scrub: false use_gmt_hitset: 1 auid: 0 fast_read: 0 Appreciate your help.
