It finished the copy..or during = the copy I got the following:kernel : ad6 : FAILURE - device detachedkernel= : subdisk6: detachedkernel : ad6 : detachedkernel : GEOM_MIRROR : device d= at : provider ad6 disconnected.kernel : g_vfs_done():mirror/dats1d[READ(off= set=3D196937613312, length=3D16384)]error=3D6I can only think that perhaps = its a time out or a file block error The file appears okay on ad4 and when I look at it from a NFS mount and thr= ough SAMBA on my Windows box. the configuration is roughly thus ad2 - boot drive, freeBSD installedad4 - 320G SATAad6 - 320G SATA - compon= ents of mirror dat I used round-robin priority. So I am not sure if the fai= lure is copying the large file from ad6->ad4? or from ad4->ad6. I presume it is the latter, so would wonder why I got a R= EAD error and not a write. I put a newfs on ad4 but not ad6 when I was building the mirror. I put the = label on ad4 during install (also put newfs during install). Did not put la= bel on on ad6, did not put a newfs on ad6. I Thought the gmirror would take= care of that, at any rate it has been working. I have put other files of s= everal hundred megabytes without a problem. But when I tried this 1.8G file= this error happened. I have checked the file systems on each device and th= ey appear identical...could be because of the mirror I am reporting only on= ad4 and fooling me? Now I can see some internet documents on this where the newfs should be run= on the mirror. Is this the correct procedure to ensure the file blocks are mapped properly on each drive. The drive, as = I have said, has some files on it already and has been working=20 fine for a couple of week. It is not a heavily loaded server, its why I am = using a slower machine. I would appreciate any tips on determining why this happened and whether I = built the mirror properly. =20 Thanks, Sal _________________________________________________________________ All new Live Search at Live.com http://clk.atdmt.com/UKM/go/msnnkmgl0010000006ukm/direct/01/=
