Multiple Disks created on Live Migration
Hi All,
Iam using CS 4.3.1
When ever i have live migrated the root volume from one primary to another
primary, it will creates two root disks after migration and the vm boots
from one of the root disk.
is this bug?
Regards,
Rajasekhar.

Hi ilya,
I am using ACS 4.3.1 with xenserver 6.2
During live migration of root disks, creates two disks in primary
storage.CS know about one disk and doesn,t know about second disk.I
manually tried to boot from second disk by updating volumes table(to check
second disk is useful or not),but CS is throwing error saying invalid uuid
supplied,but in primary storage both disks are showing full size.
Will CloudStack accept to boot vm from outside disks?
Regards,
Rajasekhar.

That wont work. You should not bypass cloudstack in this manner as it
keeps track of all configs in its DB.
When you do stop and start VM, it recreated the config file each time.
If you were to add another disk or make any changes outside of
cloudstack, they will not be persistent.
This could be a bug, but i'm surprised why no-one else reported this
behavior yet.
Tell us about your setup.
Regards
ilya

Hi Andrija,
I have a small doubt here,why the xenserver is creating two root disks.
by default cloudstack will boot from one disk,i manually made it to boot
from another disk by updating volumes table(since two disks are showing
full size) ,now cloudstack is throwing error invalid uuid supplied.
any idea?
one thing we have to observe here is cloudstack doesn't know about the
second disk.

2 volumes are showed while migration is running - old volume should be
deleted afterwards...
