Did you manage to get the engine log with DD_MASK=all, that will give us more information about why the engine is not completing start-up (and why you don’t have any joined ranks reported by "dmg system query").

The load blobstore failed message is expected. It just means they need to be created.

 

Also can you please confirm that you have tried with the adjusted settings as per previous e-mail:

"- set engines->targets to 4 and engines->nr_xs_helpers to 0"

 

Regards,

Tom

Hi Tom,
I noticed an error in the engine log.
DAOS[11610/11614] bio  DBUG src/bio/bio_xstream.c:662 load_blobstore() load blobstore failed -1025
Is it because of this? And what does "-1025" mean?

Some parameters of calling spdk_bs_load are as follows:
bs_dev->blocklen = 512
bs_dev->blockcnt = 7814037168
bs_opts.max_md_ops = 32
bs_opts.max_channel_ops = 4096
bs_opts.cluster_sz = 1073741824

And the memory information of the server is as follows:
