sda1 size  ~ 21.5 G

but using df:
# df -kh
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdb6             7.7G  5.6G  1.8G  77% /
tmpfs                1014M     0 1014M   0% /dev/shm
/dev/sda1             190M  5.6M  175M   4% /mnt/sda1

sda1 size = 190M

df comes from the file system rather than the partition.  is it
possible that the sda1 partition was resized but not reformatted?

if you can stand to lose the data, can you reformat the file system?
do you then get the expected size?
Or just try "resize2fs /dev/sda1" to resize the filesystem to the size of the underlying partition.
