Description

Assuming you have a mounted lustre file system at /mnt/lustre, and a running copytool for it, the next commands should reproduce the issue:

[root] # useradd alice
[root] # mkdir /mnt/lustre/alice
[root] # chown alice: /mnt/lustre/alice
[root] # su - alice
[alice] $ touch /mnt/lustre/alice/file
[alice] $ chmod o+w /mnt/lustre/alice/file
[alice] $ exit
logout
[root] # lfs hsm_archive /mnt/lustre/alice/file
[root] # lfs hsm_state /mnt/lustre/alice/file
/mnt/lustre/alice/file: (0x00000009) exists archived, archive_id:1
[root] # useradd bob
[root] # su - bob
[bob] $ echo "123" > /mnt/lustre/alice/file
[bob] $ exit
logout
[root] # lfs hsm_state /mnt/lustre/alice/file
/mnt/lustre/alice/file: (0x00000009) exists archived, archive_id:1
[root] # dmesg | tail -n 2
