Hi All, how can I determine the size of each I/O? does it depend on the cluster size? block size? will it be different for each file system if each of those have different cluster size? I am just trying to understand very high I/O wait on our oracle RAC DB, where as we dont have it on another server with similar load. if the DB need 4K will it fetch only 4K? on side note, I know in ZFS it pulls

Hello, I have a Centos 6.2 clsuter with a CLVM partition on which I have a GFS2 file system. The problem rises when I make a snapshot from my FC NetAPP FAS2020. After I make the snapshot (it is a rw snapshot) of my LUN, I am not able to mount it from any of my cluster nodes, because the Physical Volume is seen two times one time on the standard LVM partition and the other time on the snapshot

dear R experts--- I am experimenting with multicore processing, so far with pretty disappointing results. Here is my simple example: A <- 100000 randvalues <- abs(rnorm(A)) minfn <- function( x, i ) { log(abs(x))+x^3+i/A+randvalues[i] } ?## an arbitrary function ARGV <- commandArgs(trailingOnly=TRUE) if (ARGV[1] == "do-onecore") { ?library(foreach) ?discard <-

Hive <http://hadoop.apache.org/hive/> is a data warehouse infrastructure built on top of Hadoop that provides tools to enable easy data summarization, adhoc querying and analysis of large datasets data stored in Hadoop files. It provides a mechanism to put structure on this data and it also provides a simple query language called QL which is based on SQL and which enables users familiar with
