I have an ISO datastore. In that datastore I'm using symlinks to point
to my ISOs on an NFS share. All was working great.
Along comes Black Friday and a shiny new 3TB hard drive. Out goes the 5
yo old 500gb drive with EXT 4 and in comes new 3TB drive with BTRFS.
I installed new drive, shutdown VMs and use tar c | tar x to move data
over. unmount old, remount new. Fire up VMs, all us well. Create new
VM, attach boot ISO and I get:
VM Gremlin is down. Exit message: internal error process exited while

My NFS server is Solaris 11.1, ZFS storage.
I'm a bit confused now, is the NFS server linux or Solaris? ZFS or BTRFS?
If I copy the ISO directly to the directory it works fine. What am I
missing?
Maybe selinux labeling?
What happens if you (temporarily!) set selinux to permissive with
"setenforce 0"?
Which user owns the file? What are the permissions on the file? And on the
rest of the iso store?
Any logging on the NFS server? Can you mount the ISO store from a different
server?

Yup!

That fixed it....What's going on? I can su - vdsm and do an md5sum on
all the ISOs. Why can't they be accessed via ovirt?
I have a local datastore on the same volume in another directory tree
that's working just fine.
Why is selinux allowing local access, but not NFS via symlink? getsebool

That fixed it....What's going on? I can su - vdsm and do an
md5sum on all the
ISOs. Why can't they be accessed via ovirt?
Seems similar to
https://bugzilla.redhat.com/1023970 although it's opened on hosted-engine.
I have a local datastore on the same volume in another directory tree
that's
working just fine.
Why is selinux allowing local access, but not NFS via symlink?
getsebool
shows virt_use_nfs --> on. What other label do I need?
Thanks for the help!
