Is there any trick to Resize LVM online that raw by UDEV rule without filesystem?
First find the disk names and paths:

select name, failgroup, path, os_mb, total_mb, free_mb from v$asm_disk;


After you found the ASM generated name for the disk you want to shrink, reduce it in ASM to the desired size (I will assume it is called DATA1_0002:

alter diskgroup data1 resize disk DATA1_0002 size 90G;


This starts a rebalance, wait until the rebalance completes, you can view its progress as:

select * from v$asm_operation;


After the rebalance, run this query again:

select name, failgroup, path, os_mb, total_mb, free_mb from v$asm_disk;


There you should see the original 184320 OS_MB, and 92160 TOTAL_MB for the disks you have just shrinked. Next use lvreduce to shrink the LV:

lvreduce -L 90G vg_db/Lv_OraD2


Make sure you do not reduce the size of LV below the ASM disk size TOTAL_MB.

Once it is done, increase the other LV:

lvextend -L 90G g_db/Lv_OraD1


Go back to ASM, run this again:

select name, failgroup, path, os_mb, total_mb, free_mb from v$asm_disk;


Here the OS_MB for the first disk should increase to 92160, but TOTAL_MB still remain 2048.

The final step is to increase the first disk size in ASM:

alter diskgroup data1 resize all;


The above will resize all ASM disks in the diskgroup up to OS_MB. This triggers another short rebalance, and when that finished, you should see 92160 for OS_MB and TOTAL_MB for both disks.
