环境rx3600 11.31 +EMC CX3存储
操作过程如下:
因要给共享磁盘(50G)扩容,在存储上存储上新建一lun(500G),系统识别如下:
# diskinfo /dev/rdisk/disk17
SCSI describe of /dev/rdisk/disk17:
vendor: DGC
product id: RAID 5
type: direct access
size: 524288000 Kbytes
bytes per sector: 512
新磁盘添加到原先存在的vg上,信息如下:
VG Name /dev/vgoradata
VG Write Access read/write
VG Status available, exclusive
Max LV 255
Cur LV 2
Open LV 2
Max PV 16
Cur PV 2
Act PV 2
Max PE per PV 1016
VGDA 4
PE Size (Mbytes) 128
Total PE 1415
Alloc PE 1200
Free PE 215
Total PVG 0
Total Spare PVs 0
Total Spare PVs in use 0
VG Version 1.0
VG Max Size 2032g
VG Max Extents 16256
给lv扩容的时候报如下信息:
lvextend: Not enough free physical extents available.
Logical volume "/dev/vgoradata/lv_oradata" could not be extended.
Failure possibly caused by strict allocation policy
Command Unsuccessful
press enter Key to continue
最后,该lv只能扩到100多G,连200G都提示上述信息
LV Name /dev/vgoradata/lv_oradata
LV Status available/syncd
LV Size (Mbytes) 102400
Current LE 800
Allocated PE 800
Used PV 2
因该lv下已经有数据,无法删除重建,怀疑是否是powerpath问题,请高人赐教,感激之至。
