Redis 2.0.3 没有让遥控器文件 appendonly.aof 后 BGREWRITEAOF

Ubuntu 10.04.2, Redis 2.0.3 (在问题结束时阅读更多).

我的文件。 AOF 为了 Redis 它变得太大，这在一定程度上很快就可以使用略微硬盘在我的VPS服务器上取得所有可用磁盘空间：

$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda 32G 24G 6.7G 78% /
$ ls -la
total 3866688
drwxr-xr-x 2 redis redis 4096 2011-03-02 00:11 .
drwxr-xr-x 29 root root 4096 2011-01-24 15:58 ..
-rw-r----- 1 redis redis 3923246988 2011-03-02 00:14 appendonly.aof
-rw-rw---- 1 redis redis 32356467 2011-03-02 00:11 dump.rdb
当我跑步时

        BGREWRITEAOF

      

, 文件 AOF 缩小，但磁盘空间未发布：

$ ls -la
total 95440
drwxr-xr-x 2 redis redis 4096 2011-03-02 00:17 .
drwxr-xr-x 29 root root 4096 2011-01-24 15:58 ..
-rw-rw---- 1 redis redis 65137639 2011-03-02 00:17 appendonly.aof
-rw-rw---- 1 redis redis 32476167 2011-03-02 00:17 dump.rdb
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda 32G 24G 6.7G 78% /
当然， Redis 仍然保留远程文件：

$ sudo lsof -p6916
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
...
redis-ser 6916 redis 7r REG 202,0 3923957317 918129 /var/lib/redis/appendonly.aof (deleted)
...
redis-ser 6916 redis 10w REG 202,0 66952615 917507 /var/lib/redis/appendonly.aof
...
我怎样才能解决这个问题？ 这次我可以重新启动 Redis, 但我真的想定期避免这种情况。

请注意，我无法更新 2.2 (虽然更新是 2.0.4 可能).
