[Pvfs2-developers] no space left on device when running on amazon ec2

[Dimos Stamatakis]

Hello!
I have successfully run a pvfs installation on a eucalyptus cloud, but when
I moved to Amazon EC2, I get a very strange error.
When I run a metadata server it says:

[S 02/20 00:04] PVFS2 Server ready.

and then it says:

[E 02/20 00:04] batch_create request got: No space left on device
....... And this error repeats ......

I checked all of my devices and there is plenty of space, so I don't think
there is not enough space left...
Can you explain that?
What is the batch_create function? And where is it trying to write?

Here is the output of the df -h on the data node:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             9.9G  2.7G  6.8G  29% /
tmpfs                 308M     0  308M   0% /lib/init/rw
udev                   10M  108K  9.9M   2% /dev
tmpfs                 308M  4.0K  308M   1% /dev/shm

and on the meta data node:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             9.9G  2.0G  7.5G  21% /
tmpfs                 308M     0  308M   0% /lib/init/rw
udev                   10M  108K  9.9M   2% /dev
tmpfs                 308M  4.0K  308M   1% /dev/shm

Many thanks,
Dimos.
