May 2021 - Devel - Nfs Ganesha List Archives

by Bjorn Leffler

Apart from the counters that you can access through dbus, is there any other monitoring built into Ganesha? I'm thinking of adding it with this higher level plan: - Exporting metrics from Ganesha to Prometheus. - Aggregate data in Prometheus. - Display monitoring consoles and graphs with Grafana. - Package up Prometheus, Grafana and the preconfigured rules/dashboards as a Docker image. - This makes it straightforward to deploy monitoring alongside a Gansha binary. My rough coding plan for the code is to: - Add a USE_MONITORING directive to the CMakeLists.txt files. - Add a build dependency to the Prometheus C client <https://github.com/digitalocean/prometheus-client-c>. - Create a src/monitoring directory for the new source files and templates. - Increment counters and timers throughout the code. - Use histograms to compute latency percentiles, heatmaps, etc. Is this a good idea? Any objections or suggestions? Thanks, Bjorn

NFS over UNIX domain socket

by matvore＠comcast.net

Hello, It turns out that the macOS NFS client supports connecting to an NFS server over AF_LOCAL (UNIX domain) sockets. It is undocumented, but a hint of this is here: https://github.com/apple/darwin-xnu/blob/xnu-7195.101.1/bsd/nfs/nfs_subs.... This has performance improvements over using IP loopback. I'm wondering if this area has ever been explored or worked on? After a quick look I feel it should be an approachable task. There is already AF_VSOCK support, which sounds very similar. FWIW it looks like this was upgraded from a debug build feature around 2020-02: https://github.com/apple/darwin-xnu/blame/18c0ee9fc565c37827391eaa2f42f26... Thank you, Matt

FSAL read and ERR_FSAL_DELAY

by Suhrud Patankar

Hello All, We want to serve read in case of a slow backend and would like the client to retry the read op. mdc_read_super_cb() calls mdcache_kill_entry() if FSAL returns eDelay. This ends up cleaning the state for the file including any byte range locks. Does this mean eDealy is not a valid error for FSAL read? How do I return ERR_FSAL_DELAY from FSAL without losing the state? Thanks in advance for your help! Thanks & Regards, Suhrud
