Hi, Yes this is a known issue -- an mtime can be in the future, and an rctime won't go backwards. There was an earlier attempt to allow fixing the rctimes but this got stuck and needs effort to bring it up to date: https://github.com/ceph/ceph/pull/37938 Cheers, dan On Sun, Dec 18, 2022 at 12:23 PM Stolte, Felix <f.stolte@xxxxxxxxxxxxx> wrote: > > Hi guys, > > i want to use ceph.dir.rctime for backup purposes. Unfortunately there are some files in our filesystem which have a ctime of years in the future. This is reflected correctly by ceph.dir.rctime. I changed the the time of this files to now (just did a touch on the file), but rctime stays the same. I waited one day and remounted the filesytem, but the value of rctime stays the same. > > It is possible to update the ceph.dir.rctime in some way or is it hard coded, that rctime will never be decreased? > > Regards > Felix > > --------------------------------------------------------------------------------------------- > --------------------------------------------------------------------------------------------- > Forschungszentrum Juelich GmbH > 52425 Juelich > Sitz der Gesellschaft: Juelich > Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
