Oracle Linux 6.5
Oracle ASM 11.2.0.4
Virtualised Server (VMware)
I have /dev/sdb as a scisi (VM) disk of 1TB. Single partition (/dev/sdb4) on it - with /dev/sdb4 being used as an ASM disk in a diskgroup (external redundancy). Partitioning is used to isolate sysadmins from using ASM disks, and isolate DBAs from using cooked file systems as ASM candidate disks.
VM admin bumped the size of /dev/sdb up with a few 100Gb. I forced the kernel to rescan the drive and it correctly detected the new disk size.
Now for the issue - how does one force a resize of partition without stuffing up ASM, and the contents of the partition?
Googling returned various discussions on this - but all of them pertain to cooked file system partitions. And suggests deleting the partition and recreating it, without impacting the partition's contents.
Not sure how safe an approach this would be on a partition being used as a raw device by ASM.
Suggestions and comments on how to address this issue will be appreciated.
