Thomas,

Thanks for the quick response. To confirm, use of atime with rbh-find will compare times to the last_access time?

Yes.
I understand this can be confusing but last_access is taken as the last activity on the file (max(atime, mtime, ctime))
which appears to be a suitable criteria for purge policies in particular.

Regards.

Craig

    Hi Craig,

    rbh's last_mod = stat's mtime
    rbh's last_access = max(atime, mtime, ctime)
    with Lustre changelogs:
        rbh creation is the timestamp of the CREATE record of the entry
    when scanning :
        rbh creation is the ctime of the entry the first time it was seen.

    Regards
    Thomas

    Hello,

    I have a question regarding the difference in names of timestamps
    used in Robinhood.  When I run stat on a file, it reports 3
    times.  These are Access, Change, and Modify.  When I run
    rbh-report --entry-info on the same file, Robinhood uses
    creation, last_access, and last_mod.

    Are last_access from RBH and Access from stat supposed to be the
    same?  What about Modify and last_mod?  How does the timestamp
    Change from stat and creation from RBH relate?

    Thanks,
    Craig
