Hello, We're building a new collectd + RRD server on Ubuntu 12.04. I'm wondering if anyone has any thoughts on filesystem tuning (and filesystem format). We have created a ~1 TB RAID 5 volume over local SSD drives for the RRD filesystem.
Is there a favoured filesystem? Currently it's ext4. Should we consider / benchmark anything else? Normally I think smaller block size is recommended for RRD file systems, but given we have pretty large RRD files (eg 30 MB - we keep a lot of high resolution metrics) - perhaps this isn't as important? Journaling? mount options: - noatime - nodiratime - discard - anything else? Does the libeatmydata LD_PRELOAD library help smooth out disk IO / increase effective throughput? Thanks for your thoughts! Jesse _______________________________________________ collectd mailing list [email protected] http://mailman.verplant.org/listinfo/collectd
