When this happens, I see this log line from the rgw component in the FSAL:

2018-02-13 12:24:15.434086 7ff4e2ffd700  0 lookup_handle handle lookup failed <13234489286997512229,9160472602707183340>(need persistent handles)

For a short time, I cannot stat the mentioned directories. After a minute or so, they "reappear".

I found this message in https://github.com/ceph/ceph/blob/master/src/rgw/rgw_file.h

Cheers,

Martin

Hi!

I am trying out NFS-Ganesha-RGW (2.5.4 and also Git V2.5-stable) with Ceph 12.2.2.

Mounting the RGW works fine, but if I try to archive all files, some paths seem to "disappear":

...

...

* all paths here are actually "directories" (with more objects "in them")
* Multiple runs yield the same paths, so it appears not to be random.

Anyone seen this? Could this be some timeout issue?


Thanks

Martin
