Hi, I have a Production database (11.2.0.3) sitting on a RHET 6.3 platform RAC cluster with ASM storage, and everything working normally, but I am running out of space in one of the disk groups.
I have new disk capacity to add to this disk group, but when I perform the following OS command from root no entries are returned:
/etc/init.d/oracleasm listdisks
If I go into ASMCMD and perform lsdsk, I get the following returned:
/dev/mapper/oradata
/dev/mapper/oraflash
Also if I connect to the ASM instance from grid username and perform the following I get the following:
SQL> select name from V$ASM_DISKGROUP;
NAME
------------------------------
DATA
FLASH
My question is why /etc/init.d/oracleasm listdisks command returns no entries? Note I have already performed the /etc/init.d/oracleasm scandisks on both nodes.
The disk I wish to add is called /dev/mapper/oradata2
When I go to perform the /etc/init.d/oracleasm createdisk DATA2 /dev/mapper/oradata2 to create the disk, and run the scandisks on both nodes, I assume the listdisks will still not be able to list the Data, Flash and Data2 disks
My big concern is that when I add create the disk on Node1, Node2 might not be able to see the newly created disk when I run the Scandisks command.
Any help here would be appreciated.
