Re: [zfs-discuss] ZFS/Lustre echo 0 >> max_cached_mb chewing 100% cpu
This probably belongs on the Lustre mailing list. Regardless, I don''t think you want to do that (do you?). It''ll prevent any client side caching, and more importantly, I don''t think it''s a case that''s been tested/optimized. What''re you trying to acheive? Also, just curious, where''s the CPU time being spent? What process and/or kernel thread? What are the top entries listed when you run "perf top"? -- Cheers, Prakash On Tue, Oct 22, 2013 at 12:53:44PM +0100, Andrew Holway wrote:> Hello, > > I have just setup a "toy" lustre setup using this guide here: > http://zfsonlinux.org/lustre and have this process chewing 100% cpu. > > sh -c echo 0 >> /proc/fs/lustre/llite/lustre-ffff88006b0c7c00/max_cached_mb > > Until I get something more beasty I am using my desktop machine with > KVM.
