Hey, http://xfs.org/docs/xfsdocs-xml-dev/XFS_Filesystem_Structure/tmp/en-US/html/Allocation_Groups.html "Each AG can be up to one terabyte in size (512 bytes * 2^31), regardless of the underlying device's sector size." "The only global information maintained by the first AG (primary) is free space across the filesystem and total inode counts" Checkout this link: http://osvault.blogspot.de/2011/03/fixing-1tbyte-inode-problem-in-xfs-file.html , maybe your first AG (0) is full.
