That is a good question. The 2.0 installer uses pc-sysinstaller which I am not entirely sure if it takes into account this or not.

The 2.0 installer uses pc-sysinstaller which I am not entirely sure if it takes into account this or not. I did an install yesterday and worked on this. I manually changed geometry to 32 heads and 32 sectors and adjusted the cylinders count accordingly, but when I tried to create my partitions the installer insisted on changing the sector count to a number that was divisible by 1008 (in fact the number I gave it was divisible by both 1008 and 1024, but it still complained for some reason). I partitioned with Linux fdisk and then skipped formatting and partitioning with the pfsense installer, as recommended by the installer. I found the whole thing quite confusing, and I'm not 100% positive that I ended up with the desired result, but this is due in part to my lack of understanding of BSD slices. It would be nice to have an installer that automatically handles this, as some SSDs perform hugely better with their partition boundaries aligned to the flash's erase block boundaries, as can be seen on anantech.com's SSD Bench. Not a big issue for standard installs, perhaps, but potentially significant on a loaded squid box, which is exactly my intention. Thanks for the response. Looking forward to this in 2.1. db - To unsubscribe, e-mail: support-unsubscr...@pfsense.com For additional commands, e-mail: support-h...@pfsense.com Commercial support available - https://portal.pfsense.org
[pfSense Support] SSD partition alignment in 2.0
Is the 2.0 installer aware of 4k sector discs, and does it align its partitions accordingly?
