Hi, Sorry if this is a bit of a chestnut, but I notice that http://docs.openstack.org/developer/swift/deployment_guide.html recommends:
$ mount -t xfs -o noatime,nodiratime,nobarrier,logbufs=8 /dev/sda1 /srv/node/sda in particular the 'nobarrier' is of interest here. It seems to me that there should be qualifiers mentioning the disk cache setting at least (i.e disabled) and perhaps the cache+battery settings for any adapter card that the disk device is plugged into. Otherwise there is a risk of data loss or corruption on host power loss that could take a long time for the various updater, auditor processes to pick up let alone fix. Thoughts? regards Mark _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
