Hi Stefan ,
what do you mean > By the way you only have this issue with "oracleasm createdisk" ?
In link you have provided , they can't create oracleasm disk even if they have partition -->
"Marking disk "/dev/emcpowera1" as an ASM disk:"
asmtool: Device "/dev/emcpowera1" is not a partition
In Oracle documentation and in any other sources everywhere used partitions for "oracleasm createdisk"
and moreover only one single partition preferable.
- Note:Oracle recommends that you create a single whole-disk partition on each disk to use.
- Use either
fdisk
orparted
to create a single whole-disk partition on the disk devices to use.
