环境:VMware Workstation
Centos7.2 x64
出现故障:
在两块磁盘上划分两个分区做PV(Physical Volume):
修改两个分区ID为8e
pvcreate /dev/sdb7 /dev/sdc7
Can't open /dev/sdb7 exclusively. Mounted filesystem?
因为这两块磁盘之前用来做过软Raid5,所以先卸载Raid5,然后删除。
umount /dev/md5
mdadm -S /dev/md5 //停止md5
rm /dev/md5 //删除md5
再次
pvcreate /dev/sdb7 /dev/sdc7
Can't open /dev/sdb7 exclusively. Mounted filesystem?
检查/etc/fstab文件,发现在该文件中有/dev/md5的项目,删除该项目
pvcreate /dev/sdb7 /dev/sdc7
WARNING: linux_raid_member signature detected on /dev/sdb7 at offset 4096. Wipe it? [y/n]: y
Wiping linux_raid_member signature on /dev/sdb7.
Physical volume "/dev/sdb7" successfully created
创建成功!
还有很多问题不明白,在停止md5,rm /dev/md5以后,使用命令cat /proc/mdstat还可以看到Raid信息,期望大神看到可以解答一下,万分感谢!
