[Moosefs-users] Cannot write to mounted filesystem

[Dennis J. <den...@co...>]

Hi,
I'm starting to play with MooseFS and while the setup seemed to work fine I 
ran into trouble after mounting it.

My Setup is a Centos 6 host system and four Centos 6 virtual machines 
installed as master, metalogger and two chunk servers.
Installing everything went smoothly and I can see the two chunk server in 
the cgi stats interface. Both chunk servers have a 1gb partition formatted 
as ext4 mounted under /mnt/data for the storage.
The cgi interface shows 2GiB total space and 1.3GiB available.

I can mount the filesystem on a client and df -h shows 1.4G of free space 
which looks ok. However the moment I try to copy a file no matter how small 
I immediately get a "No space left on device" error. Doing a "ls" after 
that shows the file on the filesystem with a size of 0 bytes. A "mkdir 
/mnt/mfs/test" for example works fine though.

I see the following in the syslog on the client:

Jul 29 21:47:11 centos6 mfsmount[9930]: file: 6, index: 0 - fs_writechunk 
returns status 21
Jul 29 21:47:11 centos6 mfsmount[9930]: error writing file number 6: ENOSPC 
(No space left on device)

Any ideas what the problem could be?

Regards,
   Dennis
