Hello, We noticed Operation not supported (95) error returned when “lfs migrate” command being run on a directory including files which have been hsm archived to S3 on a 2.15 lustre file system with multiple MDS (DNE)
# lfs mkdir -i 0 testdir # cd testdir/ # echo "123" > a.txt # lfs hsm_archive a.txt # cd .. # lfs migrate -m 1 testdir lfs migrate: testdir/a.txt migrate failed: Operation not supported (95) Once we enable migrate_hsm_allowed, we don’t see errors/issues anymore. # lctl get_param mdt.*.migrate_hsm_allowed mdt.abcdefg-MDT0001.migrate_hsm_allowed=0 # lctl set_param mdt.*.migrate_hsm_allowed=1 mdt.abcdefg-MDT0001.migrate_hsm_allowed=1 My question is why we don’t set migrate_hsm_allowed to 1 as default value and is there concern we should know if we choose to set that to 1? Thanks! Please let me know if I can provide any more information. Thanks, Huaqing Wang
