The following is a write-up by Oracle mainline Linux kernel engineer, Darrick Wong, providing some backround on his work on Linux FS Metadata Checksumming, which, after many years of work, will will be turned on by default in the upcoming e2fsprogs 1.43 and xfsprogs 3.2.3. One of the bigger problems facing filesystems today is the problem of onlineverification of the integrity of the metadata. Even though storage bandwidthhas increased considerably and (in some cases) seek...

The following is a write-up by Oracle mainline Linux kernel engineer, Sowmini Varadhan, detailing her recent work on improving the performance of the Sunvnet driver on Linux for SPARC. Background In the typical device-driver, the Producer (I/O device) notifiesthe Consumer (device-driver) that data is available for consumptionby triggering a hardware interrupt at a fixed Interrupt Priority Level (IPL). In the purely interrupt-driven model, the Consumer then masks off any...

This is a contributed post by Oracle mainline Linux kernel developer, Liu Bo, who recently presented at the 2014 China Linux Storage and File System (CLSF) Workshop. This event was held on October 21st in Beijing. OCFS2 Xue Jiufei from Huawei showed us their work on OCFS2 of the last year,including bug fixes like "Packet loss when reconnect" and a few featureslike "Range lock based on DLM" and "Self-heal when fault recover". She also mentioned that Huawei already plans to...

Oracle Linux kernel developer, Liu Bo, will be giving a presentation on BTRFS Integrity at the Korea Linux Forum on 11th Nov 2014. In VerifyFS in Btrfs Style, Liu Bo will discuss his current work on extending BTRFS to include integrity verification: There are different scenarios where we need to check whether we can trust an FS image that was handled by other untrusted parties, that means we need to have every part of the FS unchanged. Security is indeed important at any...

Recently, Chuck Lever and Shirley Ma of the Oracle Mainline Linux kernel team have been working with the community on bringing Linux NFS over RDMA (remote direct memory access) up to full production quality. At the 2014 OpenFabrics International Developer Workshop in March/April, they presented an overview of NFSoRDMA for Linux, outlining a rationale for investing resources in the project, as well as identifying what needs to be done to bring the implementation up to...

This is a contributed post from Darrick Wong, storage engineer on the Oracle mainline Linux kernel team. The following are my notes from LSF/MM 2014 and the ext4 summit, held last week in Napa Valley, CA. Discussed the draft DIX passthrough interface. Based on Zach Brown's suggestions last week, I rolled out a version of the patch with a statically defined io extensions struct, and Martin Petersen said he'd try porting some existing asmlib clients to use the new interface,...
