This causes the namespaces requested to be 8M sized, which is too small, and hence rejected (16M minimum). The following jq query sorts it in descending size order and lets it choose the 64M region: jq -r 'sort_by(-.size) | .[].dev' > + > + available_sz=$($NDCTL list -r $region | jq -r .[].available_size) > + size=$(( available_sz/4 )) > + > + NS1=$($NDCTL create-namespace -r $region -t pmem -s $size | jq -r .dev) > + NS2=$($NDCTL create-namespace -r $region -t pmem -s $size | jq -r .dev) > + NS3=$($NDCTL create-namespace -r $region -t pmem -s $size | jq -r .dev) Since these happen in a subshell, errors are lost. Running in a subshell is fine, but we should test that the variables weren't blank: test -n "$NS1" And so on. > + > + $NDCTL disable-namespace $NS2 > + $NDCTL destroy-namespace $NS2 > + > + $NDCTL create-namespace -r $region -t pmem > +} > + > +modprobe nfit_test > +rc=1 > +init > +do_test > +_cleanup > +exit 0
Hi Vishal, Thank you for your review! I'll fix and send v3.
