/dev/sdj1 cant be first, its /dev/sda1.
My friend made a python script. take a look.
cat rebuild.py
#!/usr/bin/env python
# /dev/sdj1 /dev/sdc1 /dev/sda1 /dev/sdd1 /dev/sdh1 /dev/sdi1

from itertools import permutations;
#aLetters = ( 'a', 'c', 'd', 'h', 'i', 'j' );
aLetters = ( 'j', 'c', 'h' );
j = [];
for i in permutations(aLetters):
if i[0:3] == j[0:3]: continue;
j = i;
time.sleep(0.1);
os.system("vgchange -an vgRAID60 2>/dev/null >/dev/null");
os.system("mdadm -S /dev/md127 2>/dev/null >/dev/null");
os.system("mdadm -S /dev/md126 2>/dev/null >/dev/null");
os.system("mdadm -S /dev/md0 2>/dev/null >/dev/null");
(hStdin, hStdout) = os.popen4("mdadm --create /dev/md0 --level=6 --raid-devices=6 --assume-clean --chunk=128 /dev/sda1 /dev/sd%s1 /dev/sd%s1 /dev/sd%s1 missing missing" % (i[0:3]));
hStdin.write("y\n");
hStdin.close();
hStdout.close();
time.sleep(0.5);
(hStdin, hStdout) = os.popen4("pvck /dev/md0");
sOutput = hStdout.read();
hStdin.close();
hStdout.close();
print("/dev/sdj1 /dev/sd%s1 /dev/sd%s1 /dev/sd%s1 missing missing" % (i[0:3]));
fRAID = open("/dev/md0", 'r');
try:
fRAID.seek(4608);
sLVM = fRAID.read(128);
fRAID.close();
except:
fRAID.close();
continue;
print(sLVM);
if sOutput.find("Found label") != -1:
os.system("/bin/bash");
# os.system("vgchange -ay vgRAID60 2>/dev/null >/dev/null");
# os.system("vgmknodes");
# iExit = os.system("e2fsck -n /dev/vgRAID60/data0");

i can see the data with the combinatin below, but there is a lot of errors, sounds like a rebuild was started(beghining of the disk) then was canceled
we made a snapshot, run a e2fsck on it and im still(not now, gotta sleep) add 1 missing or 2. after the e2fsck i mount the snap, look at the data, check corruption, rince and repeat with another combination of missing and not. i rate the ones with less corruption
the only e2fsck working is with --->>> a,j,c,h,i,d
