I discovered today that my ssd pool was saying degraded. I had a spare drive still in the package. Exact brand and size. When I finally found the culprit after taking every drive out one by one and placing the new drive in, discovered the bad drive was the last one swapped out. Go figure. ( Is there anyway to actually know what drive is bad? Numbers given by TrueNAS did not match anything on the drives) I tried to add it to the pool so I could move forward . I went through the motions of doing so, just to get to the end of the process and get an error saying the drive size is too small. All of the other 7 SSD’s are 1.86 and the new drive, for some reason is saying 1.82. Is there a way to overcome this problem? Thanks.
You know your hardware and setup.
You know what you did.
You know what makes you think one drive may be defective.
We don’t, and we cannot guess from your post.
Please start again with a better, more detailed, description.

Here is the requested info. It was late and I was short on time. I already removed the bad drive as I mentioned in the previous post. The new drive is also installed. It is reporting a 1.82 size and the others are 1.86. Hope this clears things up. I will get any further info needed when I get back home from work. Thanks much.

If youre replacing the boot ssd then simply save the config file, clean install and import the config.
Hello and thanks for your response. However, it is not the boot drive. I am able to boot into the system just fine. I have eight SSD‘s and one of them failed. After figuring out which SSD was bad I replaced it with the exact brand and size SSD. I powered back on the system and tried to add the new SSD to the pool. I went through the entire process and at the end was told that I could not import the SSD to the pool because the drive size was too small at 1.82. As mentioned above, all the other SSD’s are registering as 1.86 in size so it will not allow me to add the SSD that is showing 1.82. Is there a way to get around this?
Unfortunately that does happen and you are not the only one to experience this. One reason for a SWAP partition is to allow for this fluctuation of the drive capacity. SCALE does not use SWAP but we have made an argument to include either SWAP or to tell the system to use XX MB less so this problem no longer occurs.
Your only option may be to install a larger drive, so long as it is larger then it works.
Wish it were better news.

Hello and thanks for your response. I was afraid of that. I already ordered the drive. It was double the price. I had to go to a 4 TB drive.
Mmmh, isn’t sdj1 a swap partion? If this is an older pool, it might still have them?
But not sure how you actually go about preparing a slightly smaller disk so that this works.
Also, maybe worth checking whether the SSD-manufacturer has a software tool that maybe allows changing the overprovisioning, thereby freeing up the littte extra space needed?
The swap/buffer of 2 GB can only accomodate minor variations in drive size.
1.86 vs. 1.82 TiB is about 40 GB.

Somehow I completely overlooked that…
