Hi all, On our luminous v12.2.4 ceph-fuse clients / mds the rctime is not tracking the latest inode ctime, but only the latest directory ctimes. Initial empty dir: # getfattr -d -m ceph . | egrep 'bytes|ctime' ceph.dir.rbytes="0" ceph.dir.rctime="1521043742.09466372697" Create a file, rctime is updated: # touch a # getfattr -d -m ceph . | egrep 'bytes|ctime' ceph.dir.rbytes="0" ceph.dir.rctime="1521043831.0921836283" Modify a file, rbytes is updated but not rctime: # echo hello > a # getfattr -d -m ceph . | egrep 'bytes|ctime' ceph.dir.rbytes="6" ceph.dir.rctime="1521043831.0921836283" Modify the dir, rctime is updated: # touch b # getfattr -d -m ceph . | egrep 'bytes|ctime' ceph.dir.rbytes="6" ceph.dir.rctime="1521043861.09597651370" Do others see the same rctime behaviour? Is this how it's supposed to work? Cheers, Dan _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
