When in doubt, check the source:
extern int select_g_select_nodeinfo_unpack(dynamic_plugin_data_t **nodeinfo,
Buf buffer,
uint16_t protocol_version)
{
dynamic_plugin_data_t *nodeinfo_ptr = NULL;
if (slurm_select_init(0) < 0)
return SLURM_ERROR;
nodeinfo_ptr = xmalloc(sizeof(dynamic_plugin_data_t));
*nodeinfo = nodeinfo_ptr;
if (protocol_version >= SLURM_MIN_PROTOCOL_VERSION) {
int i;
uint32_t plugin_id;
safe_unpack32(&plugin_id, buffer);
for (i=0; i<select_context_cnt; i++)
if (*(ops[i].plugin_id) == plugin_id) {
nodeinfo_ptr->plugin_id = i;
break;
}
if (i >= select_context_cnt) {
error("we don't have select plugin type %u",plugin_id);
goto unpack_error;
}
}
Your slurmd's probably haven't been reconfigured yet and are expecting the
linear plugin when they connect to the newly-restarted slurmctld. They could
probably do with a restart, assuming you've pushed-out slurm.conf changes to
them.
