No update access time of a file on CloudArray
Hello,
I'm using CloudArray with trial lisence for test and found access time of a file wasn't updated when I modified the file. The modification time was updated. Is this a design or bug? Is there a parameter to change the behavior?

Hi Yasichi,
I confirmed that on local filesystem, and NTFS (Windows share, tested
with home directory [h:]), the last access date updates to current by
simply accessing the file if the command below is run and the Windows machine
is rebooted.
Note, in the command line below you need launch command prompt as
administrator.
fsutil behavior set DisableLastAccess 0
You can check the status of the fsutil setting after reboot by
running
fsutil behavior query
This did NOT work on CloudArray share. I confirmed with engineering that for performance reasons this is
intentionally hard-coded as disabled.
Thanks,
Yi

Hi yasichi,
CloudArray is a block-level device, meaning it doesn't have any intelligence on the host level. Do you see the same behavior of other drives that are not presented by CloudArray but with same file system? Let me know!

Hi littleeliza,
Thank you for your reply.
I'm using a CIFS share on CloudArray and checking the access time of the file on the CIFS share. I understand that CloudArray doesn't have any intelligence of NAS like VNX, but I think access time should be updated when file is modified.

I understand this behavior of CloudArray is a design.
