coming back to this. I found this mail from Andreas https://lists.01.org/pipermail/hpdd-discuss/2014-October/001352.html "Multiple OI files are created for new filesystems by default. You can also cause OI Scrub to rebuild the OI file if the current OI file is corrupted or missing." "You can mount the MDT locally as type ldiskfs, rename the oi.16 file, then mount the MDT as type lustre and OI scrub should begin automatically at mount (see "lctl get_param . " Does that mean that - going into downtime - backup the MDT - mount MDT as ldiskfs - rename (or move) oi.16 - umount MDT as ldiskfs - mount all devices back as lustre - .. wait :) Would be a valid procedure to reduce the size used on the MDT? I triggered a OI_scrub with lctl > lfsck_start -M lustre-MDT0000 -r Started LFSCK on the device lustre-MDT0000. and this finished: name: OI_scrub magic: 0x4c5fd252 oi_files: 1 status: completed flags: param: time_since_last_completed: 5122 seconds time_since_latest_start: 12059 seconds time_since_last_checkpoint: 5122 seconds latest_start_position: 12 last_checkpoint_position: 536870913 first_failure_position: N/A checked: 69458966 updated: 0 failed: 0 prior_updated: 0 noscrub: 190241 igif: 1719 success_count: 2 run_time: 6937 seconds average_speed: 10012 objects/sec real-time_speed: N/A current_position: N/A lf_scanned: 0 lf_reparied: 0 lf_failed: 0 but not much space was freed.
