Dear All, I'm using metadata repair tools to repair a damaged MDS following below document. My storage has about 276TB data. Cephfs-data-scan is using 32 workers. How long will it take to finish scanning extents? What about scanning inodes? It has run 6 hours and metadata pool dropped 1G. Is this normal? Thanks. ceph df --- RAW STORAGE --- CLASS SIZE AVAIL USED RAW USED %RAW USED hdd 1.3 PiB 454 TiB 835 TiB 835 TiB 64.79 ssd 7.1 TiB 6.2 TiB 878 GiB 878 GiB 12.15 TOTAL 1.3 PiB 460 TiB 836 TiB 836 TiB 64.50 --- POOLS --- POOL ID PGS STORED OBJECTS USED %USED MAX AVAIL cephfs_data 1 4096 276 TiB 222.96M 828 TiB 71.28 111 TiB cephfs_metadata 2 32 101 GiB 5.83M 302 GiB 0.09 111 TiB device_health_metrics 10 1 239 MiB 251 716 MiB 0 112 TiB cephfs_ssd 11 32 117 GiB 1.49M 361 GiB 5.83 1.9 TiB https://docs.ceph.com/en/latest/cephfs/disaster-recovery-experts/ Justin Li Senior Technical Officer School of Information Technology Faculty of Science, Engineering and Built Environment Request for assistance can be lodged to the SIT Technical Team using this form<https://deakinesmprod.service-now.com/esc?id=sc_cat_item&sys_id=7afa8fa5db62e9101acbdbf2f39619a7> Deakin University Melbourne Burwood Campus, 221 Burwood Highway, Burwood, VIC 3125 +61 3 9246 8932 justin.li@deakin.edu.au<mailto:justin.li@deakin.edu.au> http://www.deakin.edu.au<http://www.deakin.edu.au/> Deakin University CRICOS Provider Code 00113B Important Notice: The contents of this email are intended solely for the named addressee and are confidential; any unauthorised use, reproduction or storage of the contents is expressly prohibited.
