[ovirt-users] Users Digest, Vol 55, Issue 124

[Charles Tassell]

Hi Nick,

Try running "ls -l 
/rhev/data-center/00000001-0001-0001-0001-00000000037d/88dfff37-4ad5-446c-a957-1cf67829c9a6/images/da93350c-8926-42bf-99fa-8a7aca043fcd/22e7803d-e266-4e3e-ae34-0181f8acef8b" 
and check the ownership of the file.  It should be owned by vdsm:kvm (or 
user and group 36:36 I think) Another thing to check would be that the 
parent directories are accessible.  Try running "sudo -s /bin/bash vdsm" 
and then "cd 
/rhev/data-center/00000001-0001-0001-0001-00000000037d/88dfff37-4ad5-446c-a957-1cf67829c9a6/images" 
to make sure you can access all the parent folders.  If you can, try 
creating a temp file ("echo hello >hello") in that same directory to 
make sure that the iSCSI mount hasn't gone read only.

If none of that helps, I'd say take a look at the output of vgdisplay to 
make sure that the volume group still has free physical extents (Free 
PE/Size near the bottom)  If you are using thin provisioning that might 
be an issue.

This is all based on the issue being disk permission errors.  It might 
be an error with the libvirt authentication, but I have no idea how to 
diagnose that.

Permission denied
.

My ovirt installation is composed of thefollowing:

- 1 manager (virtualized)
- 1 host
- storage iscsi

Everything seems to work well from the web administration portal, but
all vm do not start.

I attach a log file.

Please help me!

Nick
