...ats-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.

But how and what happened in the background? And why I can't I see the attribute with getfattr again? getfattr -dm- /mnt/gluster/gv0_glusterfs # file:
