mkfs -t xfs /dev/<devfile>where /dev/<devfile> is the partition where you wish to create the filesystem (note that this will destroy any filesystem currently on that partition).
For example, to create a filesystem on the 3rd partition of your 2nd SCSI drive, you would use the command:
mkfs -t xfs /dev/sdb3
One important option that you may need is "-f" which will force the creation of a new filesystem, if a filesystem already exists on that partition. Again, note that this will destroy all data currently on that partition:
mkfs -t xfs -f /dev/<devfile>
You may also achieve better performance by increasing the logfile size from the default size of 1200 blocks to, say, 8000 blocks. You can do this by creating the filesystem with the command:
mkfs -t xfs -l internal,size=8000b -d name=/dev/<devfile>Other options are available for XFS filesystem creation; see the man pages for more information.
mount -t xfs /dev/<devfile> /<mount_pt>where /dev/<devfile> is the device containing the filesystem, and /<mount_pt> is the mount point for the filesystem.
Since XFS is a journaling filesystem, before it mounts the filesystem,
it will check the transaction log
for any unfinished transactions, and bring the filesystem up to date.
Welcome to a fsck-free world!
