error to run VM
by Halimaton Saadiah 12 Nov '14

12 Nov '14

Hello I am using ovirt-engine version 3.4 , currently having problems to run VM, and get error VM Debian is down. Exit message: child quit during startup handshake: Input/output error. Before this, I manage to run VM Debian then after installation complete , I shut it down and when run it back I unable to run it back as it mentioned the error "cannot run VM low disk space on target storage domain local_storage." I do check my server df -h , yes I have too much space on the root partition where all the ovirt-engine setup was there, but we have more unused space at /home partition, then what I do after that we copy the images(iso file) for that particular vm into the /home partition then rename it according to path stated at the ISO_DOMAIN. By doing all the process I can't manage to run the VM yet and get the error message stated that "VM Debian is down. Exit message: child quit during startup handshake: Input/output error." Is there anyone can help us to solve this problems, or give us the solution that we can figure out on how can we run the VM. Thank you in advance.

oVirt 3.5: Issue with FC Storage on EL7 host
by The Austrian 12 Nov '14

12 Nov '14

Just a heads up I ran into an issue with adding a Fibre Channel storage domain on a CentOS 7 host. vdsm-4.16.7-1.gitdb83943.el7.x86_64 from oVirt 3.5 Release repo This version of vdsm still has the code in /usr/share/vdsm/storage/hba.py that performs issue_lip to rescan fibre channel HBAs. In my setup, the HBA paths are still recovering when 'dmsetup status' is run resulting in paths being offline and the LUNs being made unavailable to oVirt (UI shows exclamation mark). Issue discussed here: https://bugzilla.redhat.com/show_bug.cgi?id=1159839 Quick workaround that worked for me: (1) Comment line 107 in /usr/share/vdsm/storage/multipath.py i.e.: #supervdsm.getProxy().hbaRescan() (2) Restart supervdsmd systemctl restart supervdsmd.service Regards Paul

replace ovirt engine host
by ml ml 12 Nov '14

12 Nov '14

Hello List, currently i am testing backup and restore of my ovirt engine host. So far the backup and recovery works. Since i have a nfs ISO_DOMAIN i need to remount the nfs mounts on my vdsm hosts/nodes. This is kinda ugly but okay :) However, my storage information seems to go weird. It looks like the ovirt engine gets confused about the current status. Do i have to restart vdsm after replacing the ovirt engine? When i put connect my original ovirt engine again the cluster status is okay... I test this by unplugging the original ovirt engine host network cable and doing a restore on a connrected 2nd machine. So i guess my question is: How do i replace my ovirt engine smoothly in a production enviorment? Thanks, Mario

Multiple ISO Storage Domains
by Phil Daws 12 Nov '14

12 Nov '14

Hello: How does one create multiple ISO domains ? if I try it just throws a general error "Error while executing action New NFS Storage Domain: Error creating a storage domain". And if the question is asked why would one require multiple ISO domains its when one has clusters in multiple data centers. Thanks, Phil
