</span>Webservices running with the kubernetes backend [0] have demonstrated<br class="gmail_msg">
much faster NFS access for things like Python virtualenvs. This is<br class="gmail_msg">
because the kubernetes containers (called "pods" in the upstream<br class="gmail_msg">
documentation) are configured to use an NFS cache layer that is not<br class="gmail_msg">
enabled on the OGE grid nodes or the bastions.<br class="gmail_msg">
<br class="gmail_msg">
The reasons that the grid and bastions do not have this NFS cache<br class="gmail_msg">
enabled are a bit murky, but at some point in the past it was the<br class="gmail_msg">
cache was disabled as a potential fix for a problem with stale data<br class="gmail_msg">
being read by some tools/bots. The techops team is cautious about<br class="gmail_msg">
changing the settings to re-enable the cache due lack of understanding<br class="gmail_msg">
about what could break as a result. Since the kubernetes environment<br class="gmail_msg">
is opt-in and new, they were confident that enabling the cache system<br class="gmail_msg">
there would not cause unknown problems.<br class="gmail_msg">
<br class="gmail_msg">
The larger issue of NFS slowness is to some extent a side effect of<br class="gmail_msg">
the growth of Tool Labs usage. More users, tools, and bots reading and<br class="gmail_msg">
writing files on the NFS shares cause more contention for the finite<br class="gmail_msg">
resources the underlying NFS servers have. A project has been underway<br class="gmail_msg">
for several months to migrate the NFS services to a new set of<br class="gmail_msg">
servers. This migration is currently scheduled to complete on November<br class="gmail_msg">
14th [1]. There are no guarantees that NFS access will be<br class="gmail_msg">
significantly faster once the new servers are in use, but the setup<br class="gmail_msg">
will be better documented and more familiar to the Labs techops team.<br class="gmail_msg">
That should make it easier for them to troubleshoot issues and work<br class="gmail_msg">
towards providing a better experience for all of us.<br class="gmail_msg">
