Given a host set with homogenous hardware configuration it should now be possible to generate an optimal server configuration file for DAOS using the command ‘dmg config generate’, more details are in

We have recently learned of a serious issue affecting systems with Apache Pass DCPM modules. The ipmctl utility (versions 02.00.00.3809 through 02.00.00.3816) was released with a bug that can cause th

I realise that the problem is the bdev_exclude devices are already bound to UIO at the time that DAOS starts and are not actively unbound by SPDK setup script. 0000:00:04.1 (8086 2021): Already using

Hello Anton Doesn’t look like the bdev_exclude list is being honoured, I’m on leave today but will verify behavior on master tomorrow and supply fix if broken. Regards, Tom Nabarro – DCG/ESAD M: +44 (

Hello Anton helper_log_file and bdev_exclude parameters are both global parameters and should be included in the top section (just under control_log_file), see utils/config/daos_server.yml for referen

Bdev_exclude should work in this situation, could you please share the server config file and enable and share the privileged helper log file by setting "helper_log_file: /tmp/daos_admin.log” (or simi

Yes , this is a bug with current centos7 kernel and ndctl, I will find the ticket number Regards, Tom Nabarro – DCG/ESAD M: +44 (0)7786 260986 Skype: tom.nabarro

I’m sorry I’m unfamiliar with the spdk rpc client, we manually parse the ini-style config file and directly call the SPDK configuration API all within src/bio/bio_xstream.c: bio_nvme_init(). Regards,

Yes, this is how we configure the build, thanks for the use case explanation. 293 commands=['./configure --prefix="$SPDK_PREFIX"' \ 294 ' --disable-tests --without-vhost --without-crypto' \ 295 ' --wi

In order to get DAOS up and running with NVMe-oF I think some internal changes in bio might be needed. Does the use of NVMe-oF provide specific benefits in a DAOS installation? Would like to understan

Hello Gert and Lee, https://github.com/daos-stack/daos/pull/3480 has been merged with master to fix this issue. dpdk (used as the default environment for spdk) is using weak symbols when linking: "dpd

Can now reproduce locally and working to find a solution.

Hello Gert, I can’t see anything obviously wrong with bringup and hugepage allocation, did you reboot the nodes (just as a sanity check)? The next steps I will take is to get in touch with SPDK folks

Hello Gert, It’s likely the thread lib init failure is due to a problem with hugepages configuration as spdk_thread_lib_init() only calls spdk_mempool_create(). Can you please do some debug as follows

Thanks Gurt, Yes, that was only to get the identify application running, which looks like it runs fine as expected given the problem looks like initializing the thread library which identify doesn’t d

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_INVA

Hello Gert, ./identify error can be fixed by pre-fixing command with "LD_LIBRARY_PATH=/path/to/spdk/libs" which in your case is probably /root/daos/install/prereq/dev/spdk/lib/libspdk_sock_posix.so.2.

Sounds like maybe metadata is out of sync, can you try removing /mnt/daos0/*, starting the server and then (on a separate tty) reformatting with "dmg storage format --reformat"?

Hello Richard "ERROR: DAOS I/O Server exited with error: /usr/bin/daos_io_server (instance 0) exited: exit status 1” indicates that there might be some useful information in the io_server log for the
