Hi

Thats my current script to get all vm names from the cluster. Afterwards I check the new name against the list to prevent errors.

#!/usr/bin/env bash
nodes=$(pvesh get  /nodes/ 2>/dev/null  | sed -n -E '/\"id\"/ s/.*:\s\"(.*)\".*/\1/p' | sed -n -E 's/node/nodes/p' )
vms=$(for i in $nodes ; do vms=$(pvesh get $i/qemu/ 2>/dev/null | sed -n -E '/vmid/ s/.*:\s(.*[^\s]).*/\/qemu\/\1/p') ; for q in $vms ; do echo $i$q ; done  ; done )
for i in $vms ; do pvesh get $i/config 2>/dev/null | sed -n -E '/\"name\"/ s/.*:\s\"(.*[^\"])\".*/\1/p' | xargs echo "vm $i has name"  ; done

But its so SLOOOOOWWWWW

Any better ideas ?

Mit freundlichen Grüßen / With kind regards
