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 […]


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 […]


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 […]

This lighttpd module provides for mapping different parts of the host filesystem in the document tree. You can use it for mapping various directories. For example cgi-bin directory mapped to /var/lib/cgi-bin. The alias module is used to specify a special document-root for a given url-subset. Configuration Open your lighttpd configuration file: vi /etc/lighttpd/lighttpd.conf Append/add mod_ […]


df displays the amount of disk space available on the file system containing each file name argument. If no file name is given, the space available on all currently mounted file systems is shown. Read man page of df if you are new to df command. Steps => Find disk space using df => Filter […]


The idea and commands in this article submitted by Jacques Wagener via email. In his own words, “After nuking my partition by accident (and through my stupidity) I was really disappointed in myself, especially in losing my bookmarks and rss-feeds”. The following article is based upon our email communication. I am just putting them as […]


If you are using hot swappable hard disk and created new partition using fdisk then you need to reboot Linux based system to get partition recognized. Without reboot you will NOT able to create filesystem on your newly created or modified partitions with the mke2fs command.

However with partprobe command you should able to create a new file system without rebooting the box. It is a program that informs the operating system kernel of partition table changes, by requesting that the operating system re-read the partition table.
