FastDFS中Trunk文件使用 出現(xiàn)新數(shù)據(jù)和舊數(shù)據(jù)無法同步的現(xiàn)象。請問可以手動同步嗎？可以的話能不能提供一下操作步驟。謝謝！回復(fù) 1# happy_fish100

@happy_fish100   魚大大好，想問下我使用了連接池（java client），并且tracker.conf和storage.conf都啟動了連接池（use_connection_pool = true），為何在我的機(jī)器上（java client）看到和trakcer建立的連接很少很少，我設(shè)置的連接池是1000個，fdfs版本5.08 服務(wù)器系統(tǒng)為CentOS6.5 64bit

你好，，，我的跟你是同樣的問題，，，也是在另外一個機(jī)房單獨(dú)增加一個storage，這臺storage是內(nèi)網(wǎng)機(jī)器，沒外網(wǎng)，做了NAT上網(wǎng)，
給機(jī)器映射了23000端口，在tracker上也添加了id配置，啟動storage報錯,,,,你的怎樣解決的，，，

魚大：你好，我在使用 append接口上傳的文件時，fastDHT 不會對這種類型的文件進(jìn)行去重?  有沒有修改文件標(biāo)識的接口，我先傳一個文件為可以append的文件，等我把后續(xù)的文件都上傳完成的時候，在改變文件類型為 普通文件。這樣fastDHT 在對它進(jìn)行去重？

跪求解決啊，用fastdfs一段時間了，http訪問資源（tracker訪問方式）在一個時間點(diǎn)突然不行了，在此之前上傳的文件通過tracker都訪問不了，訪問通過日志看就會說找不到文件，非tracker依然可以訪問，奇怪的是重新上傳的文件通過tracker訪問依然是可以的。 fastdfs  http解決方案用的是apache，兩臺跟蹤，三臺存儲（兩個分組），我把配置貼出來，老大看看是怎么回事啊。
tracker機(jī)器上的http擴(kuò)展配置：
兩臺跟蹤 10.12.5.54、10.12.5.57除了主機(jī)IP，http配置都是一樣的：
LoadModule fastdfs_module modules/mod_fastdfs.so
<VirtualHost *:80>
Servername 10.12.5.54
<Location /group1/M00>
sethandler fastdfs
</Location>
<Location /group2/M00>
sethandler fastdfs
</Location>
</VirtualHost>

三臺存儲除了ip 以及配置分組都是一樣的：
LoadModule fastdfs_module modules/mod_fastdfs.so
<VirtualHost *:80>
        Servername 10.12.5.55
        <Location /group1/M00>
                sethandler fastdfs
        </Location>
</VirtualHost>

fastdfs http擴(kuò)展，無論nginx還是apache，剛上傳的文件使用tracker訪問可以正常訪問，文件上傳大概一天多，使用tracker訪問方式就不行了，非tracker訪問還是可以的，是什么問題啊魚大大
