Collateral Missing After Upgrade of CC Sector

[William8Work]

I upgraded a CC sector using mark-for-upgrade but after it's upgraded with a deal, the PreCommit and Commit were all looked normal (see below). However, I couldn't find where the collateral is returned or re-used from the original sector.

The original sector 102 has some collaterals (see the on-chain-info details below). However, during the upgrade with the deal, the PreCommit message costs and the Commit costs are the same as the non-upgrade sectors. Where did the original collaterals go?

Logging Information

Here is what I found in the miner log:

2021-09-04T23:02:36.048-0700    INFO    sectors storage-sealing/upgrade_queue.go:71     replacing sector 102 with 8718

Repo Steps

1. Run '...'
2. Do '...'
3. See error '...'
   ...

InitialPledge only represents how much pledge a sector costs and doesn't imply any balance movement as of today, since the new replacement sector is a completely new sector on-chain.

That being said, original ticket info doesn't imply any bug. However, it can use a discussion for the community to 💬 and dig into upgrade cc sector's mechanism.

[William8Work]

Thanks @jennijuju for moving this to a discussion. I think logically when the upgrade happens, the lotus miner will do the following:

1. The deal sector will be sealed normally, marking "ReplaceCapacity" = yes, and set the "ReplaceSector" with the sector number that's being upgraded.
2. During the next Window Post,
   1). Refund the collateral to miner available balance from the CC sector has been upgraded successfully.
   2). The CC sector has been upgraded successfully will be changed to Active = NO, and its expiration will be set to 0
   3). Remove the CC sectors that Active = No from physical storage so that the storage space is freed up for future usage (nice to have).
