Can I clone sda to sdb with this Python program?
filein = open('/dev/sda', 'rb')
fileout = open('/dev/sdb', 'wb')
while True:
tmp = filein.read(100000)
fileout.write(tmp)
filein.close()
fileout.close()
Your script will not work entirely, no. For instance, how will you exit from the loop on EOF?
But more to the point, why use Python for this task? Why not
dd? It already handles all the cases you would need to deal with for this task.(Substitute your favorite blocksize for
1024k.)
