Hi, I am using the vmstat that came along with the SuSE 7.0 distribution. I have problem interpretting the data reported by vmstat. The vmstat document reads that the block information reported is always in terms of 1K blocks. Just to findout the validity of the data reported by vmstat, I carried out the a small copy test. Here is the configuration I have 1) I have two file systems which are created with 4096 block size 2) These two file systems are on two different disks. (but both are sitting on same scsi controller) 3) I am trying to copy a 4GB file from one disk to another using the simple "cp" command. 4) I am capturing vmstat with 30 sec interval. I stop the vmstat after cp is done 5) The copy takes anywhere between 7 to 10 minutes. On vmstat report has bi and bo's ranging form 700 to 4000. Just to get the total blocks read, I multiple the value reported in bi column with 30 (as 30 sec was my sampling interval) and sum them all. To my surprise, they add up only to around (1 GB). What is wrong here, the documentation or my intepretation of vmstat output. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
