Hi I am trying to stop the storage pool through php-libvirt api which is a LVM volume group.
when I tried to stop it I got error
error: internal error Child process (/sbin/vgchange -aln mylvmgrp) unexpected exit status 5: Can't deactivate volume group "mylvmgrp" with 4 open logical volume(s)
Then I tried throggh virsh command but the result remain same.
*root@kvm02:~# virsh pool-destroy vms* error: Failed to destroy pool vms error: internal error Child process (/sbin/vgchange -aln mylvmgrp) unexpected exit status 5: Can't deactivate volume group "mylvmgrp" with 4 open logical volume(s)
This indicates some process(s) are still using the logical volumes so it is preventingn you breaking those apps. This is expected behaviour.
The same error also occured if I use direct vgchange -aln on my kvm host, but then I tried
*vgchange -aly mylvmgrp*
this time its worked
That is a totally different operation -aly *activates* volumes which is the exact opposite of what 'pool-destroy' needs, which is to de-activate the volumes
14 logical volume(s) in volume group "mylvmgrp" now active
1) Now would you please help me? is this libvirt issue? or LVM? 2) Is this possible virsh pool-destroy pool also run the vgchange -aly instead of -aln
AFAICT, there's no bug here. You just need to stop using the volumes before stopping the pool.
