I am using XFS on small HDD (/dev/sdb1, less than 1TB) and storing many small files (-32KB). df -h and -i show that it has available space.
# df -hv
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 127G 19G 102G 16% /
tmpfs 16G 0 16G 0% /lib/init/rw

# df -iv

/dev/sdb1 24905120 11076608 13828512 45% /mnt/sdb1
However I got No space left on device error.
# touch /mnt/sdb1/test
touch: cannot touch `/mnt/sdb1/test': No space left on device
I think inode64 issue is not related to this case because drive is less than 1TB and df -i shows that there are free inodes. I unmounted and mounted with -o inode64 but got the same error.
xfs_repair does not report any problem. xfs_info shows drive information as follows.
# xfs_info /dev/sdb1
meta-data=/dev/sdb1 isize=1024 agcount=16, agsize=2227764 blks

Any ideas? Thanks!
