Hi all, anybody knows what ptlrpcd is good for, what it might be doing? I''ve seen it eating 100% CPU on OSS where I reformated an OST, but also in other circumstances. Regards, Thomas

Thomas, To my knowledge, ''ptlrpcd'' is a thread that''s responsible for pushing asynchronous rpc requests to various places. It is also tasked with receiving the replies to those requests. I imagine the OSS has a lot of outstanding async rpc''s which need to be continually processed. It''s just a hunch.. I haven''t dug around in the OSS enough to know exactly what''s going on. paul Nicholas Henke wrote:> Thomas Roth wrote: > >> Hi all, >> >> anybody knows what ptlrpcd is good for, what it might be doing?
