Adding a XFS filesystem to CentOS 5

Install RPM's

 Note: Due to this bug (3205), install binutils to overcome the error "xargs: nm: No such file or directory" while installing kmod-xfs-xen.

# yum install binutils
# yum install xfsprogs yum-kmod kmod-xfs-xen 

Check

A chunk of disk (2TB) has been allocated to a LVM partition for the VM, which is formatted with XFS. The device is mapped into the VM as /dev/xvdc1 (i.e. a whole device, c.f. partitioned device).

Before using the filesystem, perform a check:

# xfs_check /dev/xvdc1

Note: xfs_check requires a significant chunk of memory to run. With 2Gbyte of swap and 1Gbyte of RAM a check was unsuccessful.

Mount

Mount the disk by using it's volume label. The label can be verified with the xfs_admin program:

# xfs_admin -l /dev/xvdc1
label = "purple-files"

Add the mount entry to '/etc/fstab' so that the filesystem is automatically mounted at the next restart.

LABEL=purple-files      /files                  xfs     defaults        0 0

Mount the filesystem

# mount /files

# yum install xfsprogs yum-kmod kmod-xfs-xen
