OpenOffice works fine for the same user with a home directory on the local disk.  I suspect this has something to do with file locking or some unorthodox file handling tricks by OpenOffice.  Is this a known problem?  And, if so, is there a workaround?

Thanks... this is very encouraging!  We are also using Ubuntu 10.04 and 
would like to start migrating users from local home directories to a 
single MooseFS volume.  But we need to get OpenOffice behaving well with 
MooseFS before we can continue.

May I ask some details of the options used to export MooseFS from the 
server and the options used for mounting on the client?  And you are 
using the Ubuntu OpenOffice package (version 3.2)?  Which version of 
MooseFS are you using?

It looks like I'm having the same problem as reported in this OpenOffice 
bug:

<http://openoffice.org/bugzilla/show_bug.cgi?id=113207&historysort=new>

strace is showing these related lines (OpenOffice appears to be 
truncating a file that it has just unlinked!):
     [pid 22207] open("/net/post/stevew/.execoooh0c2YJ", 
O_RDWR|O_CREAT|O_EXCL, 0600) = 25
     [pid 22207] unlink("/net/post/stevew/.execoooh0c2YJ") = 0
     [pid 22207] ftruncate(25, 4096)         = -1 EPERM (Operation not 
permitted)
     [pid 22207] mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED, 25, 
0) = 0xb3faf000
     [pid 22207] mmap2(NULL, 4096, PROT_READ|PROT_EXEC, MAP_SHARED, 25, 
0) = 0x459000
     [pid 22207] --- SIGBUS (Bus error) @ 0 (0) ---

Thanks and best regards,
