I reinstalled my operating system (now a kubuntu 13.10 x64) and i need to remount my fake raid 4 (3 disks). Can someone help with ideas ?

sudo dmraid -r
/dev/sde: isw, "isw_bbcbheecjj", GROUP, ok, 3907029166 sectors, data@ 0
/dev/sdd: isw, "isw_bbcbheecjj", GROUP, ok, 3907029166 sectors, data@ 0
/dev/sdc: isw, "isw_bbcbheecjj", GROUP, ok, 3907029166 sectors, data@ 0

sudo mdadm --assemble --scan
mdadm: Container /dev/md/imsm0 has been assembled with 3 drives
mdadm: Started /dev/md/raid5 with 3 devices

sudo mount -t ext4 /dev/md/raid5 /data
mount: wrong fs type, bad option, bad superblock on /dev/md126,
   missing codepage or helper program, or other error
   In some cases useful info is found in syslog - try
   dmesg | tail  or so

What am i doing wrong ?

Edit :

  cat /proc/mdstat 
Personalities : [raid6] [raid5] [raid4] 
md126 : active raid5 sdd[2] sdc[1] sde[0]
  3907023872 blocks super external:/md127/0 level 5, 128k chunk, algorithm 0 [3/3] [UUU]
  [===>.................]  resync = 16.4% (321975552/1953512064) finish=171.9min speed=158160K/sec

md127 : inactive sde[2](S) sdc[1](S) sdd[0](S)
  7548 blocks super external:imsm

Can i cancel the sync ?
