Dear All, In reference to this issue about SSD's and partition alignment at http://kerneltrap.org/mailarchive/freebsd-fs/2009/1/5/4601614 I have been struggling a few hours with installing FreeBSD on a SSD attached to a VIA-EPIA Mini ITX board with the VIA PLE133 Chipset on it. I have choosen FreeBSD specifically because it appeared already running as os with samba on this commercial NAS-device based on the VIA EPIA board with many interesting neglected features. The 5400rpm internal drive is retired from today. After getting a lot of inode errors when trying to install FreeBSD 7.2 on a OCZ PATA 120GB SSD attached to IDE1 interface of the board I ended up to follow up the Geometry reported by the BIOS C/H/S = 61865/16/255 . Surprisingly or maybe not surprisingly to readers here no inode errors anymore during a full installation! I do have some concerns though regarding wearing and performance ( degradation)such as: - The default newfs args -b 16384 -f 2048 will this be in harmony? - Currently 1GB memory onboard and default 2GB swap is defined on the SSD. - etc. out of my current perception... Further it is a great learning project since this board is more than 6 years old but reasonable in power consumption. the ultimate goal is to create a thinfat client annex voip videophone multimedia box which will be able to connect to a virtualized featherweight virtual machine somewhere. if kerneloptimalisation is required for this than it be so. looking forward to any constructive input. cheers, Fred
