Thanks. This worked. I am back with degraded mode.

 mdadm --create --verbose /dev/md5 --level=5 --chunk=128 
--raid-devices=6 /dev/hde1 /dev/hdf1 /dev/hdg1 /dev/hdh1 /dev/hdi1 missing

Hi Sharif,

From the kernel log, I believe that the raid5 array now has 4 working

disks out of 6 raid disks.  My suggestion is to recreate the array.

Before recreating the MD array, I would suggest that you run mdadm
--examine /dev/hdxx (i.e. hde1, hdf1 or hdg1) and write down the
information of the original array setup.
Some of the important Raid5 info are : Raid Devices, Total Devices,
Preferred Minor (/dev/mdx), Spare Devices, Layout, Chunk Size, order of
devices.
When you **decide** to use mdadm -C to recreate array, mdadm will ask
you to confirm on overwriting existing md superblock.
 

Thanks for your response. Will it delete the existing the data on the 
RAID?
