Expand LUN
I'm trying to expand a LUN size on my server. I've expanded it on storage (compellent) and linux can see the new size on "fdisk -l" but when I try to expand it on Veritas I receive the error message "Cannot remove last disk in disk group. Resizing this device can result in data loss. Use -f option to force resize".
-f option is to force resize, is it possible to resize it with no data loss?
Commands and outputs:
vxdisk list
DEVICE TYPE DISK GROUP STATUS
compelnt0_0 auto:cdsdisk data01 oradg01 online thinrclm
compelnt0_1 auto:cdsdisk data02 oradg02 online thinrclm
sda auto:none - - online invalid
vxdisk -g oradg02 resize compelnt0_1
VxVM vxdisk ERROR V-5-1-17027 Device compelnt0_1: resize failed: Cannot remove last disk in disk group. Resizing this device can result in data loss. Use -f option to force resize
