Andrew Browne ARC Using up all available RAM

ZFS ARC can consume a lot of RAM. It'll pretty much use all it can, and it usually does. A friend of mine commented that having no free RAM available was a strange idea. He didn't like the thought of those resources being taken. Heres a little analogy I thought up to explain why the ARC using your available RAM is good.. Imagine you have a fridge (your RAM), down the road is a shop selling a variety of food and you can get it all for free - the only cost is the time it takes you to walk down th… Continue

Eloszor is, qemuban telepitett 0906 svn 111a verziot hasznaltam, de 0811-ben is valtozatlanul ugyanigy van minden. Mivel ez egy tesztkornyezet, a teszteket egy, a rpoolon letrehozott volumeon vegzem:

Marc Moreau My OpenSolaris beginnings

I installed OpenSolaris today as a VirtualBox client following the instructions given in [1]. I am primarily a Linux guy so I don't really know what to expect from OpenSolaris. Is it Solaris with an opensourced kernel, a cross between the GNU/Linux world and Solaris or something completely different? We will see. My primary reason for install OpenSolaris is to play with ZFS. Having worked with ZFS in a production environment for about year, I recently started looking into how ZFS actually works… Continue

Hai-Ou Jiang 在Linux下使用ZFS

ZFS文件系统是Sun公司开发的第一个128位的具有革命意义的文件系统，目前在FreeBSD及Mac OS X等Unix系统上已经引入了ZFS文件系统。 由于Solaris的CDDL开源协议和Linux的GPL开源协议不兼容，所以ZFS一直没有在Linux上直接实现。但是人们仍可以从 opensolaris.org上下载ZFS的源代码，而在Linux上可以通过ZFS-FUSE在不违反版权声明的情况下使用ZFS。 目前ZFS-FUSE的最新版本是0.5.0，相关博客：http://zfs-on-fuse.blogspot.com/。 在Ubuntu8.10上安装zfs-fuse 0.5.0的过程如下： 1. 安装使用zfs-fuse所需要的包 sudo apt-get install build-essential libfuse-dev libaio-dev zlib1g-dev scons 2. 下载zfs-fuse 的源代码并解压 (1)可以使用wget命令下载或直接下载： wget http://download.berlios.de/zfs-fuse/zfs-f… Continue

Lincoln Bryant FreeBSD, ZFS, and a headless zombie server OF DOOM! (pt 1)

At work I have a Dell PowerVault 715N storage unit. It's a 1U NAS with four 120GB IDE drives at 7200RPM, with 1 GB of RAM and a Pentium III clocked at around 1GHz. It's headless and has a serial port and two Intel-based NICs. It's currently running Fedora Core 2. For whatever reason, Solaris doesn't have Serial port A activated by default, so I had to go in and add a serial connection for 'tip' to use. I basically followed the guide here:… Continue

Achmad Mardiansyah Solaris ZFS, basic concepts

sorry, saya jawab seadanya dulu yah, versi lengkap tentang Solaris ZFS sedang dibuat jadi artikel. Q: Apa sih yang menyebabkan zfs dikatakan filesystem yang cepat? A: ini cepat dalam hal apa? read ato write? ZFS read lebih cepat: - karena dia pake algoritma ARC yang bisa memprediksi data yang akan dibaca. - karena dia pake COW (lihat penjelasan dibawah) - pada pool standar, ZFS pake dynamic striping, jadi data yang ditulis akan disebar kebeberapa disks. sehingga kalo baca diambil dari be… Continue
