Integrate fio & bdevio with SPDK backend and RBD/LSVD as part of GitHub actions #31

Open knikolla opened 4 months ago

knikolla commented 4 months ago

Outgrowth of #30

knikolla commented 2 months ago

Made progress getting bdevio tests to run on a RBD (non LSVD backend)

Starting bdevio with the -w flag starts SPDK and awaits RPC calls to configure the bdev and perform tests.
