Chapril » Infra Chapril

Sur le SI April, il a été mis en évidence que la charge I/O est proportionnelle au nombre de snapshots des vm.

Actuellement, sur le SI Chapril :

#!/bin/bash
vmlist=$( virsh list | tail +3 | head -n -1 | awk '{ print $2 }' )
printf "VM              Name                    Creation Time               State\n" 
echo "-------------------------------------------------------------------------" 
for vm in $vmlist; do
    #echo "== $vm";
    while read line; do
          printf "$vm\t\t$line\n";
    done < <(virsh snapshot-list $vm | tail +3 | head -n -1)
done

Donc, effectivement, il existe des snapshots devenus inutiles dont on pourrait se passer.

Demande : identifier les snapshots inutiles et les supprimer.
