Hello DAOS developers and users,
I am trying to start a DAOS server of a centos 7 virtual machine for tests. I used RPMs version 1.0.3 from the Intel website and tmpfs for /mnt/daos.
If I try to execute command like "dmg pool create --scm--size=1G" the daos_server dies with the message in the log:
daostest ERROR 2021/04/06 13:09:18 DAOS I/O Server exited with error: /usr/bin/daos_io_server (instance 0) exited: signal: aborted

I suspect that some config parameters are not good and here is my config file:

# Storage definitions

# The size of ram is specified by scm_size in GB units.
scm_mount: /mnt/daos # map to -s /mnt/daos
scm_class: ram
scm_size: 4
# When bdev_class is set to file, Linux AIO will be used to emulate NVMe.

bdev_class: file
bdev_size: 16
bdev_list: [/tmp/daos-bdev]
Could you please help me to figure this out.
Best wishes
