Hi, and Happy New Year!
I met the problem in using TroveMethod directio.
pvfs2-server sometimes outputs the following error, and the clients hung up.
[D 12/31 19:15] PVFS2 Server version 2.8.1pre1-2009-12-29-100034 starting.
[E 12/31 19:15] dbpf_direct_write: failed to perform aligned write
[E 12/31 19:15] dbpf_bstream_direct_write_op_svc: failed to perform
direct locked write: (error=-1073742089)
I found that the dbpf_bstream_get_extents() sometimes returns the
extents with NULL pointer.
The attached patch solved this problem.
Could you commit this patch?
Thanks
Kazuki
