1. This is a personal debt, and you should pay it yourself. Because you wrote an iou.

2. Unless the IOU is signed by the partnership or three partners, the partnership shall bear the loan in the name of the partnership, and the other partners have the obligation to repay it.

If you have no money to repay, you can use your share in the partnership to repay. The premise is that the partnership business is ok and the partnership share is still valuable.
