    Description

      I am trying to access a file that has an ACL as root and I cannot open it:

      // -rw-rw-r--+ 1 giavitto ultrasat 22838 Jan  9 13:48 /lustre/fs24/group/ultrasat/first_light/udp_packets/sn204_shooting_v1-3_15s_pinhole_natural_light_1_with_2_zero_exposures_and_hotfixes_misalignment/2024-01-09T12-43-13/frame_009_image_0.png
      # getfacl '/lustre/fs24/group/ultrasat/first_light/udp_packets/sn204_shooting_v1-3_15s_pinhole_natural_light_1_with_2_zero_exposures_and_hotfixes_misalignment/2024-01-09T12-43-13/frame_009_image_0.png' 
      getfacl: Removing leading '/' from absolute path names
      # file: lustre/fs24/group/ultrasat/first_light/udp_packets/sn204_shooting_v1-3_15s_pinhole_natural_light_1_with_2_zero_exposures_and_hotfixes_misalignment/2024-01-09T12-43-13/frame_009_image_0.png
      # owner: giavitto
      # group: ultrasat
      user::rw-
      group::rwx                      #effective:rw-
      group:ultrasat:rwx              #effective:rw-
      mask::rw-
      other::r--
      

      When I try to copy the file, I get the error

      cp: cannot open '/lustre/fs24/group/ultrasat/first_light/udp_packets/sn204_shooting_v1-3_15s_pinhole_natural_light_1_with_2_zero_exposures_and_hotfixes_misalignment/2024-01-09T12-43-13/frame_009_image_0.png' for reading: Operation not supported

      and in the syslog this message:

      LustreError: 2481150:0:(mdc_acl.c:50:mdc_unpack_acl()) convert xattr to acl: -95
