如何手工修复(fsck)在磁阵上的文件系统？

melocy

SUN Enterprise 3000机器，磁盘阵列是SPARCStorageArray。
十年前的机器，一共2台。操作系统是5.5。
从2001年后就报废了。
为了学习solaris，又把它搬出来。开机时，报错如下：

VxVM general startup...
vxvm: vxconfigd: WARNING: Disk disk04 in group oradb: Disk device not found
vxvm: vxvol: ERROR: Changing plex vol01-02:
        Plex contains unusable subdisk
The system is comming up. Please wait.

run fsck manually (fsck filesystem ...)

请教如何手工修复(fsck)在磁阵上的文件系统。

remen

fsck -y /dev/vx/rdsk/oradb/vol01

melocy

执行fsck后报错

#fsck -y /dev/vx/rdsk/oradb/vol01
Can't open /dev/vx/rdsk/oradb/vol01

请remen指教。

remen

那就是你的这个设备根本就没有挂接上，看看物理连接！

remen

注释掉这些mount点在vfstab中，只留下/和swap，重新启动看看是否能够启动？能，则说明是阵列的问题，不能的话，boot -r,重新检测硬件，启动看看！

melocy

启动没有问题。

接阵列了。
删除dg后，如何建dg？我要用阵列建oracle数据库。
