Seeing errors like the above and trying to track down the root cause. I know that at last weeks’ GPFS User Group meeting at ORNL this very error message was discussed, but I don’t recall the details and the slides haven’t been posted to the website yet. IIRC,
the “rto” is significant …<br class="">
I’ve Googled, but haven’t gotten any hits, nor have I found anything in the GPFS 4.2.2 Problem Determination Guide.<br class="">
Thanks in advance…<br class="">
