Today I'd like to explain how to add more disk space on an existing Oracle ASM diskgroup on Linux using udev(7) instead of ASMLib.
There has been a few threads about ASM, AMSLib and udev on the oracle-l mailing list (see OCR / VD external vs. normal redundancy using NFS and High Availability Options for instance). I prefer using udev. So in this example, I will be using udev in order to add two new LUNs to the existing +FRA ASM diskgroup.
This particular ASM setup has three diskgroups: +CRS, +DATA and +FRA. The +CRS diskgroup is used for the Grid Infrastructure (GI) files (i.e. OCR and ASM spfile), the +DATA is used for the database (RDBMS) data files while the +FRA one is the Fast Recovery Area. That's the one we need to increase.
