g_vfs_done():md0[WRITE(offset=1350844416, length=16384)]error = 1

[Attila Nagy]

Hello,

I have a setup, where I have a /data filesystem with a "big" (20G) 
sparse file on it. This sparse file is set up with:
mdconfig -a -t vnode -f /data/nfsimg
and I use /dev/md0 for storing some data, shared via NFS (I needed 
redundant read only NFS servers, so I just sync this image to the others 
and mount read only on them).

With the above, I get the following in the syslog:
Feb  1 11:16:49 boot00a kernel: 
g_vfs_done():md0[WRITE(offset=1350844416, length=16384)]error = 1
Feb  1 11:16:49 boot00a kernel: 
g_vfs_done():md0[WRITE(offset=1928118272, length=16384)]error = 1
Feb  1 11:17:18 boot00a kernel: 
g_vfs_done():md0[WRITE(offset=1350844416, length=16384)]error = 1
Feb  1 11:17:18 boot00a kernel: 
g_vfs_done():md0[WRITE(offset=1928118272, length=16384)]error = 1

And these two lines are alternating, with the same offsets, as you can 
see. I use the raw device for storing the filesystem (newfs /dev/md0). 
Currently the image is mounted read-write and there is almost no 
activity on that.

Any ideas about this?

Thanks,
