This seems like a bug. If I remember correctly, you are testing the files layout, right? Does this also happen with the latest kernel v2.6.39-rc3 and / or pnfs-all-2.6.38? Regards, Benny -----Original Message----- From: quanli gui [mailto:gqlxj1987@xxxxxxxxx] Sent: Wed 2011-04-20 11:47 To: linux-pnfs; Halevy, Benny Subject: [pnfs] pnfs read layoutget In the code of linux-kernel-2.6.31, we can see that before the read operation there is the layoutget operation. But in the newly code, for example, in linux-kernel-2.6.36, before the read operation there only is the open operation. That meaning that we don't need to get the layout from the mds? Why remove the layoutget operation before the read operation? How it reflect on the source code? -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
