Hey all - Just a quick one...
Is there any plan to update the mdb ::memstat dcmd to present ZFS buffers as part of the summary? At present, we get something like: > ::memstat Page Summary Pages MB %Tot ------------ ---------------- ---------------- ---- Kernel 28859 112 13% Anon 34230 133 15% Exec and libs 10305 40 5% Page cache 16876 65 8% Free (cachelist) 26145 102 12% Free (freelist) 105176 410 47% Balloon 0 0 0% Total 221591 865 Which just (as far as I can tell) includes the zfs buffers in Kernel memory. And what I'd really like is: > ::memstat Page Summary Pages MB %Tot ------------ ---------------- ---------------- ---- Kernel 28859 112 13% Anon 34230 133 15% Exec and libs 10305 40 5% Page cache 16876 65 8% Free (cachelist) 26145 102 12% Free (zfscachelist) 1827346 1700 xx% Free (freelist) 105176 410 47% Balloon 0 0 0% Total 221591 865 Which then represents the pages that *could* be freed up by ZFS in the event that they are needed for other purposes... Any thoughts on this? Is there a great reason why we cannot do this? Also - Other utilities like vmstat, etc that print out memory... Thoughts on those guys and the way they treat the ufs buffers versus the zfs buffers? Cheers! Nathan. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
