Next steps ... build a stable filesystem and copy over the database files etc.

OK so the next step then is once that mdstat is built

Personalities : [raid10] [raid6] [raid5] [raid4]
md0 : active raid10 sdo[9] sdn[8] sdm[7] sdl[6] sdk[5] sdj[4] sdi[3] sdh[2] sdg[1] sdf[0]
      314571520 blocks 256K chunks 2 near-copies [10/10] [UUUUUUUUUU]

unused devices:

Next step is to build a filesystem on it 

mkfs.ext3 /dev/md0 

Once that is done we will temporarily call it /u02 and now we will copy over the data 

add 

/dev/md0                 /u02                    ext3    defaults       0 0

to fstab

mount /u02 

We don' want to sit and watch the copy from the u01 

  nohup cp -a -v * /u02>cp1.log 2>&1 &

so now we can log out and go off to bed. We will check in again tomorrow
