Hello,

You and Gurt are experiencing the same issue:

09/10-14:23:55.96 intel-S2600WFD DAOS[260088/260088] bio  ERR  src/bio/bio_xstream.c:367 bio_spdk_env_init() Failed to init SPDK thread lib, DER_INVAL(-1003)

09/10-14:23:55.97 intel-S2600WFD DAOS[260088/260088] server ERR  src/iosrv/init.c:521 server_init() DAOS cannot be initialized using the configured path (/mnt/daos).   Please ensure it is on a PMDK compatible file system and writeable by the current user

Which is that the SPDK thread library cannot be initialised, the thread library is not used in the identify example so that would explain why it runs fine.

spdk_thread_lib_init() is returning an error but unfortunately we wrap it with DER_INVAL and mask the spdk error, which needs fixing.

Can you please apply this patch and rerun to give us a better insight and in the meantime I will find an Ubuntu system to verify:

```
