df -k看看这个slice有没有被mount
如果没有被mount，那你就mount /dev/rdsk/cxtxdxs0 /mnt，然后cd /mnt，看看有什么东西。

从楼主的帖子上看，可能没用（过）。

有分区被mount 的盘会有警告：

先谢谢上面几位的分析,这个机器是V880,连EMC盘柜,有70块这样的盘,目前我正在看

Please try:
$ metastat | grep cxtxdxs0

小心点，如果用做raw device，那么就没有了提示。

还是综合分析一下吧。

如果查看这些盘还没有被使用,我想重新建个vg.

这些盘后面带error说明什么意思呢?

是不是还没有使用呢?
还是?

那说明这个还在使用呢?那为什么会有error标记呢?

erro没有关系的,不要管. 看起来你的内置盘用了 sds做卷的, EMC的磁盘用了veritas管理的. metstat 和vxdisk list没有显出出放在某个group里面一般就没有被使用过了.

作者: ljmok367 时间: 2006-08-25 18:13
通过楼上各位的指导,基本明白了,这个机器有六个73G内置盘,两个盘做了一个镜像,另四个盘做了RAID5,
其它EMC盘都划了METADEVICES,但我不知道METADEVICES D0-D6都被谁用了,文件系统肯定没用,
如果用于RAW设备,不知怎么划的?我因为刚接管这台机器,以后还要向各位请教
VXDISK LIST 不能用,没有VXDISK命令.

df -k看看这个slice有没有被mount
如果没有被mount，那你就mount /dev/rdsk/cxtxdxs0 /mnt，然后cd /mnt，看看有什么东西。

友情提醒

mount /dev/rdsk/cxtxdxs0 /mnt，然后cd /mnt

是不是把r去掉？
