XFS is a full 64-bit file system, it can support millions of Tera bytes of storage space. Pairs of large files and small size of documents to support both for their outstanding support of large number of directories. Maximum file size that can be supported for the 263 = 9 x 1018 = 9 exabytes, maximum file system size of 18 exabytes. check an reply.

You need to download and compile the kernel. Download the appropriate version of the kernel patch, extract the patch package on the system core patch. The core patch, download decompression, got a file: xfs-1.1-2.4.18-all.patch file. To repair the core are as follows:
# Cd / usr / src / linux
# Patch-p1 SGI XFS filesystem support # #

You need to download a complete set of tools XFSprogs packages, namely mkfs.xfs tool. Otherwise, you are unable to complete the formatting of the partition: that can not be a partition formatted XFS file system format. To download the package name: xfsprogs-2.0.3. Will be downloaded XFSProgs tool to extract, install, mkfs.xfs automatically installed in the / sbin directory.
# tar-xvf xfsprogs-2.0.3.src.tar.gz
# cd xfsprogs-2.0.3src
#. / configure
# make
# make install

To make the system use the other partition XFS file system, there are step is to migrate file system. Recommended to migrate the file system, the first data on the disk, file back up in order to avoid irreparable losses during conversion between the file system, it is best able to perform a full backup the entire system. There are many ways this step of the migration method. You can follow their own customary way to accomplish. Check and reply.

If you want a pure xfs system (the system for all file systems are used XFS file system), then had to be the root file system is also formatted as xfs file system. This is actually more complicated step. Because the root file system can not be umount, therefore, you must first create a partition, its file system as ext2 file system, then the current root partition all files and directories, faithfully copied to this one partition, and then change the / etc / fstab file, replacing the original root partition. All the best.
