Swaminathan Balachandran updated HDDS-11411:
--------------------------------------------
Description: There is a race condition where entries in the rename tables
could be inconsistent state when moving keys from a deleted snapshot to the
next snapshot in chain. If the garbage collection runs on the next snapshot
then this could lead to incorrect deletion. This would happen since data rename
entries could be in an inconsistent state. Garbage Collection should wait for
the snapshot purge to happen if the previous snapshot in chain is in deleted
state. (was: There is a race condition where entries in the rename tables
could be inconsistent state when moving keys from a deleted snapshot to the
next snapshot in chain. If the garbage collection runs on the next snapshot
then this could lead to incorrect deletion.)
> Snapshot garbage collection should not run when the keys are moved from a
> deleted snapshot to the next snapshot in the chain
