RFC: NVMf namespace masking
by Jonas Pfefferle
Hi all,
I would be happy to get some feedback on my NVMf target namespace masking
implementation using attach/detach:
https://review.spdk.io/gerrit/c/spdk/spdk/+/7821
The patch introduces namespace masking for NVMe-over-fabrics
targets by allowing to (dynamically) attach and detach
controllers to/from namespaces, cf. NVMe spec 1.4 - section 6.1.4.
Since SPDK only supports the dynamic controller model a new
controller is allocated on every fabric connect command.
This allows to attach/detach controllers of a specific
host NQN to/from a namespace. A host can only perform
operations to an active namespace. Inactive namespaces can
be listed (not supported by SPDK) but no additional
information can be retrieved:
"Unless otherwise noted, specifying an inactive NSID in a
command that uses the Namespace Identifier (NSID) field shall
cause the controller to abort the command with status
Invalid Field in Command" - NVMe spec 1.4 - section 6.1.5
Note that this patch does not implement the NVMe namespace
attachment command but allows to attach/detach via RPCs only.
To preserve current behavior all controllers are auto attached.
To not not auto attach controllers the nvmf_subsystem_add_ns
shall be called with "--no-auto-attach". We introduce two new
RPC calls:
- nvmf_ns_attach_ctrlr <subsysNQN> <NSID> [--host <hostNQN>]
- nvmf_ns_detach_ctrlr <subsysNQN> <NSID> [--host <hostNQN>]
If no host NQN is specified all controllers
(new and currently connected) will attach/detach to/from the
namespace specified.
The list in spdk_nvmf_ns is used to keep track of hostNQNs
which controllers should be attached on connect.
The active_ns array in spdk_nvmf_ctrlr is used for fast lookup
to check whether a NSID is active/inactive on command execution.
Thanks,
Jonas

[Release] 21.07: Kernel DSA, Init lib, Userspace DTrace
by Zawadzki, Tomasz
On behalf of the SPDK community I'm pleased to announce the release of SPDK 21.07!
This release contains the following new features:
- Kernel DSA: Added support in IDXD library for the kernel DSA driver.
- Init library: Added Init library that initializes the SPDK subsystems.
- Userspace DTrace: Added support running bpftrace scripts against SPDK applications. See https://spdk.io/doc/usdt.html.
- zipf utility: Added zipf random number generator with power law probability distribution. When used with bdevperf and nvme perf tools - blocks over the full range of LBAs will be used, but will more frequently select lower-numbered LBAs.
The full changelog for this release is available at:
https://github.com/spdk/spdk/releases/tag/v21.07
This release contains 711 commits from 56 authors with over 35k lines of code changed.
We'd especially like to recognize all of our first time contributors:

What version of NVMe is supported by the latest SPDK?
Is there a schedule when NVMe 2.0 will be supported?

NVMeofTCP SPDK host abort test
by Gyan Prakash
Hello all,
I am using NVMeofTCP SPDK host and running IO abort test ( build/examples
folder) to test my NVMeofTCP target. I am running abort test with
different queue depth like 4, 8, 16, 32.
Test completes fine for queue depth 4, 8, and 16 but it hangs and seems to
be in some kind of continuous loop for queue depth 32.
In network trace, I see that for queue depth 32, host has sent a write
command, target responded with r2t, host never sends the requested data.
From the host console message, it looks like the host is in a continuous
loop.
I am providing the SPDK abort command console output for q depth (-q 4, -q
16 and -q 32). Queue Depth 32 has so many errors on the host console and
same error is being printed over and over. Please see below for more
details.
Can you please let me know how can we fix this
Thanks,
GP

Preparation for SPDK 21.07 release
by Zawadzki, Tomasz
Hello all,
The merge window for SPDK 21.07 release will close by July 23rd.
Please ensure all patches you believe should be included in the release are merged to master branch by this date.
You can do it by adding a hashtag '21.07' in Gerrit on those patches.
The current set of patches that are tagged and need to be reviewed can be seen here:
https://review.spdk.io/gerrit/q/hashtag:%2221.07%22+status:open
On July 23rd new branch 'v21.07.x' will be created, and a patch on it will be tagged as release candidate.
Then, by July 30th, a formal release will take place tagging the last patch on the branch as SPDK 21.07.
Between release candidate and formal release, only critical fixes shall be backported to the 'v21.07.x' branch.
Development can continue without disruptions on 'master' branch.
Thanks,
Tomek

spdk lvstore metadata sync across nodes in a cluster
by Purushothama BM
Hi,
I am running SPDK application on nodes say Node.A & Node.B, both the nodes are accessing the shared disk D connected via network attached storage.
Creating some logical volumes(lvol) through Node.A does not appear to be visible on the Node.B unless and until the SPDK app is restarted or reloaded again.
I wanted to know if there is a way to reload/pull the metadata updates without actually reloading the SPDK app on Node.B?.
Thanks & Regards,
Purushothama BM.
