cephfs ceph.dir.rctime decrease

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
