[Clusterware] Check if storage is shared
If you suspect that your Clusterware is not working properly and you have these conditions: - Disk mapping is the same. - Disk major and minor are the same. - Instead of one cluster you have two different clusters. - You can't add a new node on the cluster....
If there is any difference between the logs, then the Voting Disk is not shared between the nodes. In that case you have to contact the system administrator to check further. Posted by Abdel Gadiel Martínez Lassonde at 7:23 AM Email This BlogThis! Share to Twitter Share to Facebook ...

ORA-19510 and ORA-27045 on RMAN Backup
Situation: Doing RMAN backup I got this error message: ORA-19510: failed to set size of 1193456 blocks for file "/backup" (block size=8192) ORA-27045: unable to close the file Linux-x86_64 Error: 5: Input/output error Cause: The backup location is a Windows...
The backup location is a Windows NFS share. It has a limitation that the backup piece cannot be greater than 2GB. Our backup piece is 9.1GB (1193456*8192/1024/1024/1024). Solution: Make the RMAN backup piece respect the file size limit. For this we can use the MAXPIECESIZE option.
