Data sharing is a must in today's modern computing world. When the data requirements include allowing a cluster of servers to access a common storage pool, Red Hat GFS is the answer for simplifying your data infrastructure, minimizing storage costs, adding storage on the fly, and achieving maximum uptime. A cluster file system like Red Hat GFS can be used with an IP network block-sharing protocol like iSCSI to provide scalable file serving at low cost. Network File System (NFS) is a common shared storage solution utilized by many infrastructures. However, in some instances, this solution does not scale. How do GFS and NFS compare? This article explains.

"LVM cannot stop/remove LV, cannot stop/delete dead RAID situation. Hi, I am having an issue with LVM and RAID in some failure cases: It seems that any operations on a LVM LV (lvchange, lvremove, etc..), require this LV's metadata to be readable. In case a LVM LV is setup ontop of a RAID 0, or a RAID 5 for instance, if two disks are lost from the RAID array, the array dies. Now that the array is dead, I would like to recreate a new RAID 0 or 5 using the remaining alive disks and some new ones. For this reason, I'd like to stop the previous dead RAID using mdadm. However, because the LVM LV does still exists, it seems to have a handle on the dead RAID, as shon below: # /opt/soma/bin/mdadm/mdadm --stop /dev/md/d0 raid manager: fail to stop array /dev/md/d0: Device or resource busy Perhaps a running process, mounted filesystem or active volume group?"

The NTFS-3G driver is a freely and commercially available and supported read/write NTFS driver for Linux, FreeBSD, Mac OS X, NetBSD, Solaris, Haiku, and other operating systems. It provides safe and fast handling of the Windows XP, Windows Server 2003, Windows 2000, Windows Vista, Windows Server 2008 and Windows 7 file systems. NTFS-3G develops, quality tests and supports a trustable, feature rich and high performance solution for hardware platforms and operating systems whose users need to reliably interoperate with NTFS. The driver is used by millions of computers, consumer electronics devices for reliable data exchange, and referenced in more than 30 computer books. Please see our test methods and testimonials on the driver quality page.

Sion is a frontend to easily manage connections to remote filesystems using GIO/GVFS. It allows you to quickly connect/mount a remote filesystem and manage bookmarks of such. It is part of the Xfce Goodies project and the Subversion respository is hosted on the Xfce servers though it doesn't have any hard Xfce dependencies and can be used on other desktop environments as well. The only hard dependency is GTK2 (2.12 or newer). GVFS is an userspace virtual filesystem and the successor of gnome-vfs but doesn't depend on Gnome itself. It only requires a recent GLib version and a properly setup DBus system. Then it provides almost transparent access to remote resources like FTP or SFTP (SSH) connections, SMB (windows shares) or special resources like the Trash (trash://), Burn (burn://) or even accessing your digital photo camera (gphoto2://). Sion itself provides a frontend to manage connections to those resources, to create bookmarks and automatically connecting to bookmarks

Red Hat Cluster Suite is a collection of technologies working together to provide data integrity and the ability to maintain application availability in the event of a failure. Administrators can deploy enterprise cluster solutions using a combination of hardware redundancy along with the failover and load-balancing technologies in Red Hat Cluster Suite.
