So.....
sdf thinks
Raid Devices : 6
others think
Raid Devices : 8
So that's not going to work.
However if we just ignore sdf, then sdg and sdi thinkg
Array UUID : a5cb0ced:fee37e80:bb291f1a:c5b2f600
while the rest think:
Array UUID : e32ad2c6:5f99dd8f:2572c3a8:c485db00
So you have at most 5 device which think they are the same array,
which isn't enough for an 8-device RAID6.
It looks like you have tried to --create the array several times,
at
Creation Time : Tue Feb 4 00:28:54 2014
Creation Time : Tue Feb 4 00:33:56 2014
Creation Time : Tue Feb 4 00:38:19 2014
to be precise.
Your only real chance is to find out the real geometry of the
array before all the problem happened, and create it properly...
It might be worth checking sda sdb and sdc (with out partitions)
as well as sdd1 sde1 sdf1 sdg1 sdi1 to see if there is anything there.
But if you have backups or some other way to regenerate the data ......
