LargeBlockSR for 4KiB blocksize disks
-
Hello again,
It is now available in 8.2.1 with the testing packages, you can install them by enabling the testing repository and updating.
Available in sm 2.30.8-10.2.yum update --enablerepo=xcp-ng-testing sm xapi-core xapi-xe xapi-docYou then need to restart the toolstack.
Afterwards, you can create SR with the command in the above post. -

Is there a way to enable this on an SR without using the xe cli? Can we specify this as an option during SR creation from XO? Or did this become the normal way to create an SR? I have both 8.2.x and 8.3, Truenas Scale and NFS shares on both.
-
@Greg_E It is a separate SR type that you can select when you create a SR in Xen Orchestra.
It's also just local SR. For NFS you still use the NFS storage driver.
-
Thanks, I was wondering if that was the case from reading the other threads.
-
@dthenot Are multiple SR-s with type=largeblock supported on the same host?
-
I don't see any reason it couldn't, but I prefer @dthenot to answer

NVMe drives attached to the PERC H965i are identified as SCSI disks in the operating system
OS exposes a 4kn nvme device on /dev/disk/by-id/scsi-36f4ee0807844d90068121b9321711e05Below is a log of creating a type=largeblock SR on latest XCP-ng 8.2
It takes about 10 minutes and some errors but it does successfully create the SR and we are able to use it.
Are all these errors expected and we can trust it's working normally?Console:

Can you try to do avgscall yourself on your host?
Does it take a long time?This exception is "normal":

It's weird though because it's the call tosr_attachthat launched the GC.
Does the GC run normally on this SR on next attempts?Otherwise, I don't see anything worrying the logs you shared.
It should be safe to use -
Hi, thank you for the response.
Currently these commands return data immediately
