请教：Disk /dev/sdj doesn't contain a valid partition table错误
各位好：请教：Disk /dev/sdj doesn't contain a valid partition table错误
我的是Hat Linux 系统，挂载IBM DS4200磁盘阵列，之前正常，目前报：Disk /dev/sdj doesn't contain a valid partition table错误 一个lun在系统中找不到；
具体排查如下；请各位帮忙看看是什么原因，是操作系统问题，还是磁盘阵列问题？

/dev/sdr1 1 1822361463810638+83Linux 没用分区表~~
新分区，用fdiskOR parted 格下，建下文件系统，就能用了。
如果LZ该分区有数据那就先备份，然后恢复分区表吧。 没有分区表
楼主之前有用format或fdisk做分区吗？
对应用有影响吗？ 几点：
你的应用时 PVG,做监控的啊，呵呵
另外，你之前肯定是可以用，我感觉是文件系统坏掉了
之前有碰到过
建议用 fsck 一下，如果不行，就只能重做了 回复 4# tech坦克
谢谢哥们~！我们的确是用的PVG的产品做的监控； 回复 2# whoiswhoz
谢谢~！现在分区表已经正常，可是，但是又出现2个LUN读写比较慢，甚至有时候不能读写，文件系统是 XFS，请问这个是怎么回事呢？ 回复 6# xxniao727
这个就比较麻烦了~~
你看看日志吧~一般XFS出错在/var/log/message里会有信息的。还有看看阵列的日志有没有错误。
PVG是什么？ 我也是遇到了这个问题。还想请教楼主是如何解决的？ 看来遇到这种问题的还不少 你好，能详细描述下这问题是怎么解决的么，对应用有影响么？谢谢！
