3ware: Add a drive to a RAID unit

Question

i've been trying to get this to work for hours and I've tried to fix it in multiple ways and it still doesn't work.

# this creates my class "bucket"
class bucket:
    def __init__(self, water, capcity):
        self.water = water
        self.capcity = capcity


# here I create my objects
bucket1 = bucket(0, 3)
bucket2 = bucket(0, 5)


# this is the printing code to print how much water there is in every bucket
def pr_v():
    print("Bucket_ONE " + str(bucket1.water) + "L")
    print("Bucket_TWO " + str(bucket2.water) + "L")
    print(" ")


# this is where my problem is
# this scirpt is supposed to trasfer water from the pouring bucket (p_bucket) to the receiving bucket untill the receiving bucket reaches it's
# capacity or the pouring bucket runs out of water
def pour_water(p_bucket, g_bucket):
    while g_bucket.capcity >= g_bucket.water or p_bucket.water != -1:
        if g_bucket.capcity != g_bucket.water or p_bucket.water != -1:

            if g_bucket.capcity < g_bucket.water:
                bucket.water = g_bucket.capcity
                break
            p_bucket.water -= 1
            g_bucket.water += 1
            pr_v()

    if p_bucket.water == -1:
        p_bucket.water = 0


# this fills the bucket to it's capacity 
def fill_water(self):
    self.water = self.capcity


fill_water(bucket2)
pour_water(bucket2, bucket1)
pr_v()

when I execute the code this happens

Bucket_ONE 1L
Bucket_TWO 4L
 
Bucket_ONE 2L
Bucket_TWO 3L

it's supposed to stop here because bucket 1 reaches its capacity

↓

Bucket_ONE 3L
Bucket_TWO 2L
 
Bucket_ONE 4L
Bucket_TWO 1L
 
Bucket_ONE 4L
Bucket_TWO 1L

why does this happen? Im new to coding so I might not know a lot of stuff

Thanks

Solution 1

Hmm, I agree, it's vague. I've always worked with spares, so drives are added automatically. Perhaps you can hack that too:

tw_cli /c0 add raidtype=spare disk=6

Then perhaps it will pick it up automatically.

Solution 2

I was able to accomplish this on my system with the following command:

tw_cli /c0/u0 start rebuild disk=6

Does the down arrow mean that you do not expect the output below, but you get it?

thank you so much! this way is much easier, but do you know why it didn't work in the first place?
