[Gluster-users] [Gluster-devel] Bitrot: Time of signing depending on the file size???

[David Spisla]

Hello Kotresh,

Yes, the fd was still open for larger files. I could verify this with a
500MiB file and some smaller files. After a specific time only the fd for
the 500MiB was up and the file still had no signature, for the smaller
files there were no fds and they already had a signature. I don't know the
reason for this. Maybe the client still keep th fd open? I opened a bug for
this:

Regards
David
