Description

I had two client with the rbytes enabled, one is kclient and another is ceph-fuse client. In kclient after I created a file in the subdir and write some contents to it and in the ceph-fuse client when stating the parent directory I didn't see the stat.size got updated, even I umount the kclient.

I need to wait for a long time or after remount the ceph-fuse client to see the size updated.

Do you have the MDS logs, Xiubo?

No, but I can reproduce it every time.

  • Subject changed from cpehfs: rbytes seems not work correctly to cephfs: rbytes seems not work correctly
  • Priority changed from Normal to Low

Setting the priority to low: rbytes is disabled by default.As directory size is recursive size with rbytes enabled,if we try to get the stats.size, mds lazilly updates the recursive stats.
