AIX 系统故障之--扩展文件系统故障


系统环境:

操作系统: AIX5300-08

Oracle: Oracle 10gR2(64)

故障现象:

smit chfs 扩展 " /" 时,提示找不到"device ",不能扩展;在rootvg 扩展pv 后,后来pv 被破坏,导致ODM出错


1、查看rootvg

[root@aix216 /]#lsvg -p rootvg

rootvg:

PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTION

hdisk0 active 546 161 107..00..00..12..42

0516-304 : Unable to find device id 0000c908116d1325 in the Device

Configuration Database.

0000c908116d1325 missing 320 320 64..64..64..64..64

[root@aix216 /]#


----尝试解决

[root@aix216 /]#redefinevg -d hdisk0 rootvg

[root@aix216 /]#lsvg -p rootvg

rootvg:

PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTION

hdisk0 active 546 161 107..00..00..12..42

[root@aix216 /]#lspv

hdisk0 0027713e1b5646e5 rootvg active


[root@aix216 /]#reducevg

0516-606 reducevg: Volume group name not entered.

Usage: reducevg [-d] [-f] VGname PVname...

Reduces volume group size by removing a physical volume.


2、从rootvg 中删除hdisk0

------ reducevg 删除pv 后,hd5 被删除

[root@aix216 /]#reducevg rootvg 0027713e1b5646e5

0516-016 ldeletepv: Cannot delete physical volume with allocated

partitions. Use either migratepv to move the partitions or

reducevg with the -d option to delete the partitions.

0516-884 reducevg: Unable to remove physical volume 0027713e1b5646e5.

[root@aix216 /]#reducevg rootvg 0027713e1b5646e5 -d

0516-306 getlvodm: Unable to find physical volume -d in the Device

Configuration Database.

0516-016 ldeletepv: Cannot delete physical volume with allocated

partitions. Use either migratepv to move the partitions or

reducevg with the -d option to delete the partitions.

0516-884 reducevg: Unable to remove physical volume 0027713e1b5646e5.

0516-306 getlvodm: Unable to find physical volume -d in the Device

Configuration Database.

0516-884 reducevg: Unable to remove physical volume -d.

[root@aix216 /]#reducevg -d rootvg 0027713e1b5646e5

0516-914 rmlv: Warning, all data belonging to logical volume

hd5 on physical volume 0027713e1b5646e5 will be destroyed.

rmlv: Do you wish to continue? y(es) n(o)?

y

0516-1246 rmlv: If hd5 is the boot logical volume, please run 'chpv -c '

as root user to clear the boot record and avoid a potential boot

off an old boot p_w_picpath that may reside on the disk from which this

logical volume is moved/removed.

rmlv: Logical volume hd5 is removed.

0516-1734 rmlv: Warning, savebase failed. Please manually run 'savebase' before rebooting.

0516-914 rmlv: Warning, all data belonging to logical volume

fwdump on physical volume 0027713e1b5646e5 will be destroyed.

rmlv: Do you wish to continue? y(es) n(o)?

yes

0516-1008 rmlv: Logical volume fwdump must be closed. If the logical volume

contains a filesystem, the umount command will close the LV device.

0516-1734 rmlv: Warning, savebase failed. Please manually run 'savebase' before rebooting.

0516-884 reducevg: Unable to remove physical volume 0027713e1b5646e5.

[root@aix216 /]#savebase

[root@aix216 /]#


[root@aix216 /tmp]#lsvg -l rootvg

rootvg:

hd6 paging 32 32 1 open/syncd N/A

hd8 jfs2log 1 1 1 open/syncd N/A

hd4 jfs2 136 136 1 open/syncd /

3、重新建立 hd5

重建hd5 ,出错

[root@aix216 /tmp]#mklv -y hd5 -t boot -a e rootvg 1

mklv -y hd5 -t boot -a e rootvg 1

0516-304 lquerypv: Unable to find device id 0000c908116d13250000000000000000 in the Device

Configuration Database.

0516-634 mklv: /tmp directory does not have enough space,

delete some files and try again.

0516-1734 mklv: Warning, savebase failed. Please manually run 'savebase' before rebooting.


[root@aix216 /tmp]#bosboot -ad /dev/ipldevice

0516-306 lslv: Unable to find hd5 in the Device

Configuration Database.


0301-168 bosboot: The current boot logical volume, /dev/hd5,

does not exist on /dev/hdisk0.

----- 提示:/tmp空间不足,实际/tmp空间很大,尝试删除tmp 下所有的文件

[root@aix216 /tmp]#df -m

[root@aix216 /tmp]# rm -rf /tmp/*


4、再次删除rootvg 下的 hdisk0


[root@aix216 /tmp]#lsvg -p rootvg

rootvg:

PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTION

hdisk0 active 546 162 108..00..00..12..42

[root@aix216 /tmp]#reducevg -d rootvg "0000c908116d1325"

0516-304 putlvodm: Unable to find device id 0000c908116d13250000000000000000 in the Device

Configuration Database.

0516-896 reducevg: Warning, cannot remove physical volume 0000c908116d1325 from

Device Configuration Database.

0516-1734 reducevg: Warning, savebase failed. Please manually run 'savebase' before rebooting.

5、重新建立 hd5

继续重建hd5 ,重建成功


[root@aix216 /tmp]#mklv -y hd5 -t boot -a e rootvg 1

mklv -y hd5 -t boot -a e rootvg 1

hd5

[root@aix216 /tmp]#bosboot -ad /dev/ipldevice


bosboot: Boot p_w_picpath is 37908 512 byte blocks.

[root@aix216 /tmp]#


6、故障解决


查看rootvg pv ,问题解决


[root@aix216 /tmp]#lsvg -p rootvg

rootvg:
