Hello,
We encountered errors after installing Oracle Clusterware, and we are trying to reattempt an installation.
Oracle 11g 10.2.0.4, VM, Linux 5 with ASMLib.
We ran the deinstall to uninstall the grid infrastructure.
We ran dd if=/dev/zero of=/dev/sdb1 bs=1024 count=100 to reset all the partitions' headers.
We ran oracleasm deletedisk to unmarked all the partitions.
We marked a disk as ASM disk on A node
#oracleasm createdisk OCR1 /dev/mapper/KAM1ODDBS08AB_OCR1p1
Writing disk header: done
Instantiating disk: done
#oracleasm listdisks
OCR1
#oracleasm querydisk /dev/mapper/KAM1ODDBS08AB_OCR1p1
Device "/dev/mapper/KAM1ODDBS08AB_OCR1p1" is marked an ASM disk with the label "OCR1"
# oracleasm scandisks
Reloading disk partitions: done
Cleaning any stale ASM disks...
Scanning system for ASM disks...
ON B node, it is not able to see the disk marked being an ASM disk
# oracleasm scandisks
Reloading disk partitions: done

Scanning system for ASM disks...
# oracleasm listdisks
# oracleasm querydisk /dev/mapper/KAM1ODDBS08AB_OCR1p1
Device "/dev/mapper/KAM1ODDBS08AB_OCR1p1" is not marked as an ASM disk
I have tried running # oracleasm init on both nodes, tried rebooting both nodes, tried # oracleasm configure on both nodes and they return the same configuration.
Please give me some ideas what could be the next thing I can check.
