As _get_log_trees() in the server prepares the log_trees item for the client's commit, it moves all the freed data extents from the log_trees item into core data extent allocator btree items. If the freed blocks are very fragmented then it can exceed a commit's metadata allocation budget trying to dirty blocks in the free data extent btree. The fix is to move the freed data extents in multiple commits. First we move a limited number in the main commit that does all the rest of the work preparing the commit. Then we try to move the remaining freed extents in multiple additional commits. Signed-off-by: Zach Brown <zab@versity.com>
