XFS can be formatted and cannot be mounted (master, urgent)-Linux general technology-Linux technology and application information. The following is a detailed description. On the CentOS 5.6 system, I want to use the XFS file system, almost all of which are configured, but the mount error occurred in the last step of File System mounting. That expert can give me some advice.
My kernel:
[Root @ cluster2 xfs] # uname-
Linux cluster2.amastor.com 2.6.18-238. el5xen #1 SMP Thu Jan 13 17:49:40 EST 2011 i686 i686 i386 GNU/Linux
XFS toolkit I installed:
[Root @ cluster2 xfs] # rpm-qa | grep xfs
Kmod-xfs-xen-0.4-2
Xfs-kmod-debuginfo-0.4-1.2.6.18_8.1.15.el5.centos.plus
Xorg-x11-xfs-1.0.2-4
Kmod-xfs-0.4-2
Kmod-xfs-PAE-0.4-2
My normal formatting:

Failed to prepare mount:
[Root @ cluster2 xfs] # mount-t xfs/dev/sdb1/xfs
Mount: wrong fs type, bad option, bad superblock on/dev/sdb1,
Missing codepage or other error
In some cases useful info is found in syslog-try

The execution prompt is as follows:
