HDDS-12560. Reclaimable Filter for Snaphost Garbage Collections #8053

swamirishi · 2025-03-11T22:49:20Z

What changes were proposed in this pull request?

Currently all garbage collection threads peek into previous snapshots to check whether a particular deleted key/deleted Directory/ RenameEntry can be removed from the system. All of these operations happen without taking locks because of which all of these threads could be working on an inconsistent snapshot data.

This patch implements a general utility class which would be responsible for opening last N snapshots from the snapshot chain corresponding to the keys bucket where N is going to be defined by the garbage collection thread based on whether if it is reclaiming a deletedKey/deletedDirectory/RenameEntry after taking a read lock on all of these snapshots. If there are lesser than N previous snapshot in the chain, only the existing snapshots would be considered and rest of them would be just marked as null. This utility class should fail opening the snapshot if any of these snaphshots are not active, since a deleted snapshot could be in an inconsistent state.

Thanks @swamirishi for the improvement and single reclaimable filter.

I mainly reviewed bd5b0c6 because it is on top of #8052

Is it needed? since the lock library will open the locks in a certain order?

yeah we don't need this anymore

We rely on this order to be right right for the garbage collection algorithm to work correctly. We are keeping the snapshot chain in the sorted order. If you want me to change that I can do that as well.

throw new IOException("Lock acquisition failed for last N snapshots: " +

qq: Is adding expectedLastNSnapshotsInChain to the log message useful?

If snapshotInfo is null there is no previous snapshot, Can we terminate this loop early?

Suggested change

while (tmpValidationSnapshotInfos.size() < numberOfPreviousSnapshotsFromChain) {

while (snapshotInfo != null && tmpValidationSnapshotInfos.size() < numberOfPreviousSnapshotsFromChain) {

Even if the snapshot info is null. We still want the previous SnapshotInfos list to be equal to the number of numberOfPreviousSnapshotsFromChain. When the snapshotInfo is null, we want the list to be filled with the required null values.

Is it lock for active OM? or more like lock manager?

You are right it is the lock manager for OM
