我在服务器上显示重复的VG名称.如何重命名其中一个VolGroup以摆脱这种冲突?

我快速尝试重新命名VolGroup(可能是这样做错了……):
- [root@dev-server dev]# vgrename /dev/cciss/c0d1 /dev/VolGroup02
- WARNING: Duplicate VG name VolGroup00: zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 (created here) takes precedence over ifDUDd-ePmZ-Er7H-xwst-70dY-hB3M-6YDNZc
- WARNING: Duplicate VG name VolGroup00: Existing zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 (created here) takes precedence over ifDUDd-ePmZ-Er7H-xwst-70dY-hB3M-6YDNZc
- Volume group name cciss/c0d1 has invalid characters
- [root@dev-server dev]#
输出df -h:
- Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00
- 30G 17G 12G 59% / /dev/cciss/c0d0p1 99M 30M 65M 32% /boot tmpfs 63G 0 63G 0% /dev/shm /dev/mapper/VolGroup00-rman

解决方法
从手册页: –
- "vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp"
- changes the name of the Volume Group with UUID Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 to "VolGroup00_tmp".
……所以你的情况: –
- vgrename zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 newvolgroupname
…将ID为zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87的卷组重命名为newvolgroupname.
