http://bugzilla.kernel.org/show_bug.cgi?id=12829

           Summary: kernel complains on ENOSPC
           Product: File System
           Version: 2.5
     KernelVersion: 2.6.29-rc6
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext4
        AssignedTo: fs_ext4@...nel-bugs.osdl.org
        ReportedBy: sandeen@...hat.com

while copying a few very large files to ext4:

mpage_da_map_blocks block allocation failed for inode 12289 at logical offset
443072 with max blocks 1036 with error -28
This should not happen.!! Data will be lost
Total free blocks count 0
Free/Dirty block details
free_blocks=0
dirty_blocks=1179
Block reservation details
i_reserved_data_blocks=1174
i_reserved_meta_blocks=5
mpage_da_map_blocks block allocation failed for inode 12289 at logical offset
444108 with max blocks 138 with error -28
This should not happen.!! Data will be lost
Total free blocks count 0
Free/Dirty block details
free_blocks=0
dirty_blocks=1179
Block reservation details
i_reserved_data_blocks=1174
i_reserved_meta_blocks=5

haven't dug into it, but this is just ENOSPC; ext4 should be more graceful.
