RE: OCR / VD external vs. normal redundancy using NFS.

I would opt to just take a filesystem backup of the nodes local drives.
When performing cluster maintenance such as upgrades or drop / add nodes I take 
a manual backup of the ocr.

Hello Dan and Freek,

That seems to be the case here. The master node (ares) has the OCR
backup file locally while the second node (enyo) dosen't have any OCR
backup files.

As we can see here from the second node, all backup files are on the first node.

[drobilla@enyo] ~ {1009}$ sudo ocrconfig -showbackup

ares     2010/07/15 07:04:47     /u01/app/11.2.0/grid/cdata/orage/backup00.ocr

ares     2010/07/15 03:04:46     /u01/app/11.2.0/grid/cdata/orage/backup01.ocr

ares     2010/07/14 23:04:45     /u01/app/11.2.0/grid/cdata/orage/backup02.ocr

ares     2010/07/14 03:04:43     /u01/app/11.2.0/grid/cdata/orage/day.ocr

ares     2010/07/12 23:04:40     /u01/app/11.2.0/grid/cdata/orage/week.ocr

ares     2010/07/14 14:17:45
/u01/app/11.2.0/grid/cdata/orage/backup_20100714_141745.ocr

ares     2010/07/14 14:17:17
/u01/app/11.2.0/grid/cdata/orage/backup_20100714_141717.ocr


Which makes me think we should change the default OCR backup location
to a shared file system like NFS or ACFS.
Any thoughts on that? Anyone using ACFS for that?
