Vivek Gite This is an interesting filesystem comparison. If you are looking to build cheap storage for personal use file system decision is quite important: This is my attempt to cut through the hype and uncertainty to find a storage subsystem that works. I compared XFS and EXT4 under Linux with ZFS under OpenSolaris. Aside from the different [...]

Vivek Gite From my mailbag: We have 5 Dell server collocated running CentOS 4.x and 5.x server operating system. Sometime my file system (ext3) goes read-only. I?d like to know what could be causing such a problem? My guess: a) Hardware problem / hard disk problem, check harddisk for errors. b) High disk I/O aka busy I/O retry error can [...]

You can quickly run grep or cat command to display the list of all supported file system. nodev indicates that the file system is not associated with a physical device such as /dev/sdb1. If you see ext3 or vfat, it means you will [...]

Vivek Gite Linus Torvalds called ZFS one of the very few bright spots in Solaris. ZFS released under Sun’s Common Development and Distribution License. Linux is under GPL v2 which makes ZFS incompatible with Linux. I?ve used ZFS under Solaris and it is absolutely rocking file system. Now this hot feature from OpenSolaris is taking a weird [...]
