SNAP Environment Variables

Supported Environment Variables

Name	Description	Default
`SNAP_RDMA_ZCOPY_ENABLE`	Enable/disable RDMA zero-copy transport type. For more info refer to section "Zero Copy (SNAP-direct)".	1 (enabled)
`NVME_BDEV_RESET_ENABLE`	It is recommended that namespaces discovered from the same remote target are not shared by different PCIe emulations. If it is desirable to do that, users should set the variable `NVME_BDEV_RESET_ENABLE` to `0`. Important By doing so, the user must ensure that SPDK bdev always completes IOs (either with success or failure) in a reasonable time. Otherwise, the system may stall until all IOs return.	1 (enabled)
`VBLK_RECOVERY_SHM`	Enable/disable virtio-blk recovery using shared memory files. This allows recovering without using `--force_in_order`.	0 (disabled)

To change the SNAP environment variables add the following to the doca_snap.yaml and continue from section "Adjusting YAML Configuration".
