Moving to storage team since the issue is the write speed of the PV.

Are you still using glusterfs or using block for Jenkins?

We are characterizing Jenkins on gluster block for 3.10.  If you are having issue with block let us know.


From the notes its not clear to me, may be reference to block is the underlying glusterfs devices. Are you looking for fine tuning the options to speed it up?

Comment 17 Sudhir 2018-10-29 15:24:31 UTC
Please let me know if the issue is related to block or glusterfs?

Can you please block and let us know if there are still issues with 3.11?
