Re: No space left on device when there is space

We had a similar Problem on Solaris 2.6 (sun4u sparc).
A 'df' showed 19% free space (about 4 GB) but it was impossible
to create one little file more in this filesystem.
(There were plenty of free inodes left too.)

You have to check as root:
        fstyp -v </dev/your/device> | less
the value for nbfree.
If this value is 0 no file can be allocated anymore - no matter of how
much free space 'df' shows.

Theoretically it would help to reduce the block size to 4096 for this
filesystem - but this is not possible for this architecure and not
for Solaris 2.6 (at least).
