Hi All
I am trying to get my feet wet with Ceph and RADOS. My aim is to use it as a block device for KVM instances. My understanding is that virtual disks get striped at 1 MB boundaries by default. Does that mean that there are going to be 1MB files on disks? Let's say I want to update a particular vdisk with 16 bytes of data at offset 4096. This would mean I want to update the first 1MB chunk. Let us assume I have 3 way replication and the replicas are A, B and C. The write may succeed at A and B and fail at C. Is there any state kept in the metadata indicating at which replicas the write succeeded? -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
