Hi @PhanLe1010,

I tested on v1.5.x head following the test plan.

When I try case 1 with a v2 volume, I hitted the permission error issue, could you take a look on this? thank you.

> k exec -it block-volume-test -- /bin/sh -c "dd if=/dev/longhorn/testblk bs=1M count=100 | md5sum"
dd: failed to open '/dev/longhorn/testblk': Permission denied

Hi @PhanLe1010 , I tried sue v1.5.x-head image to test again, still hit the permission error issue on v2 volume, the same cluster with v1.6.x images did not encounter this issue, thank you.

The issue is that instance-manager has not been updated to point to new version of longhorn-spdk-engine and go-spdk-helper

We decided to not backport this fix to v2 data engine. Please ignore the failed test for v2

Verified pass on longhorn v1.5.x (longhorn-engine 012165, longhorn-instance-manager 34d22c)

V1 volume worked well with test stpes, v2 volume not work on this ticke as this comment described.
