"no space left on device" - But df shows free space!
 

On red hat 7.1, I have a second HD /dev/hdb1 mounted, working OK.
Suddenly, when df shows 6.1Gb free, I am not able to wirte to it, with a "No space left on device" message.

(after freeing some space, I don't have problems)

Any suggestions? thanks!

Which user cannot add to theis 'full' device?

Most distro's keep 5% of the total available space for root use, all other users cannot access this free space.

How do you have your partitions setup?

I didn't try writing as root...
Would that be on any device, not only the primary?

Sorry I'm newbie and english is my second languaje,
is this an answer?
df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda2 6071936 2794544 2968944 49% /
/dev/hda4 21189048 18657960 1454736 93% /home
/dev/hda1 2044240 1277464 766776 63% /mnt/win
/dev/hdb1 38464340 22026384 14484052 61% /otherdisk

On all partitions 5% wiil be reserved for root.

So, if your home (/dev/hda4) partition is filled for another 2% (totals 95%), you won't be able to write to it (non root user).

Thanks druuna, I didn't know that!

Solved!
 

Ok, so the problem was that I had too many files on the same directory - over 1000.

Apparently, that's the limit...
