Krutikatrusted.io-stats-dump is a virtual (not physical) extended attribute.The code is written in a way that a request to set trusted.io-stats-dump gets bypassed at the io-stats translator layer on the stack and
there it gets converted into the action of dumping the statistics into the provided output file path.See io_stats_setxattr() implementation in io-stats.c for more details.HTH,On Mon, Nov 13, 2017 at 12:14 PM, Jeevan Patnaik <g1patnaik@xxxxxxxxx> wrote:Hi,I am trying to understand how the extended attribute trusted.io-stats-dump works.setfattr -n trusted.io-stats-dump -v /tmp/gluster_perf_stats/io-stats-pre.txt /mnt/gluster/gv0_glusterfs I can see that the io-stats-pre.txt is created.
