Feature Request: lvcreate with stripes option

[ddpolyakov]

I didn't find any option where I can set stripe value in case of using thick LVM.
Striping maybe useful in many cases: capacity balancing on vg, paralleling performance etc.

Sorry - I forgot to update the documentation.

You are looking for

linstor storage-pool set-property $node_name $storage_pool_name StorDriver/LvcreateType striped

Other values can be found here
https://app.swaggerhub.com/apis-docs/Linstor/Linstor/1.1.0#/developers/nodeStoragePoolModify

That value will be simply appended to Linstor's lvcreate ... --type=, whereas linear is the default

For some reason you cannot set that property on node or controller level. I will fix that in the next version.
I will also update the users-guide (after I figured out where a good place would be adding this piece of information)

I tried this:

linstor storage-pool set-property w1 nvme-lvm StorDriver/LvcreateType striped

But new volumes are still linear

I use piraeus-operator

I've managed to enable LVM striping:

linstor storage-pool set-property $host ssd-lvm StorDriver/LvcreateOptions ' -i 2'
