[libvirt-users] virsh and multi source-dev
Hi, I'm using LVM based storage pools and I'm wondering if there is a way to specify several source-dev on the command line for creating a volume group spread over several devices : one device /dev/sdc1 is ok: * virsh pool-define-as --name lvmpool --type logical --source-dev /dev/sdc1 --source-name vg --target /dev/vg I would like something like (but sadly doesn't work): ? virsh pool-define-as --name lvmpool --type logical --source-dev /dev/sdc1 --source-dev /dev/sdb1 --source-name vg --target /dev/vg ? Best regards, Matt

Thank you for answering. Yes sure I can from an xml, But is it possible from the command line with define-pool-as ? Best, Matt ----- Mail original -----

Can you define a pool xml as shown below and define it from there ?
ex: <pool type="logical"> <name>HostVG</name> <source> <device path="/dev/sda1"/> <device path="/dev/sdb1"/> <device path="/dev/sdc1"/> </source> <target> <path>/dev/HostVG</path> </target> </pool>

There are a few places where define-pool-as is still not as powerful as using full XML; but you are welcome to write a patch to improve its behavior. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
