Hi I'm the new here . And I have some questions with pmap. See `*pml4` is the physical address of a page with some flag. And then updated the address to the Direct Map Space. Then We calculate the offset of the real pdp we need . How could it access to `*pdp`? it is a virtual addr in Direct...

Hi, We're using FreeBSD server for video streaming site serving 200-4096MB size of each video. Server is built around 12 x 3TB SATA HDDs on HBA RAID-10 with 64GB DDR3 RAM. Recently we decided to add SSD as L2ARC device to cache video files and wanted to gather recommendations regarding how...

Good Morning All, I have been experiencing some mysterious thrashes on one of my servers, and I have finally gathered enough data about the problem to possibly ask for help (it was very difficult to get data since once it started thrashing there was nothing to be done except reboot...). The...

Hi, I recently added a zfs disk array to my old HP 585 G1 Server. Immediately there was kernel panics and I have spent quite a bit of time figuring out what was really wrong. The system has 4 cpu cards with opteron double core processors. Each card has 4x2 gigabyte memory 4x2x4 = 32 gigabyte...

This previously stable (2+ years) server has had 3 unexpected reboots in the last week, each time during jail-related work (creation, deletion, poudriere runs). zpool scrubs are clean, and there is no log or trace of a crash or error prior to any of the reboots. I'm considering a h/w issue but...
