log: add full time and date to the log messages

Right, it's sanlock who doesn't support it. So your text is right.

Thanks for clarification. I've attached an updated patch which
adds such a config param. It works but I can't test
live-migration at the moment. But as far as I understood it
shouldn't be a problem.

release open_disk error
by Frido Roose
Hello,
I wonder what the "open error -1" / "release open_disk error" messages in sanlock.log actually mean.
I saw these messages in the log on a KVM host that rebooted, and after running "/usr/sbin/virt-sanlock-cleanup" on that host.
The resources where disks from 2 guests running on another KVM host.
So in fact the disks are still in use, bot got cleaned up by the other KVM host because it thought they were not longer in use...
Several questions:
1. Could this indicate a problem with the lease of these resources on the server that host these guests?
2. Is there a way to reregister these resources, because they are still in use (but not for sanlock it seems)?
3. Overall, is it a bad idea to run virt-sanlock-cleanup?
Some entries from the log file:
538 s1:r35 resource __LIBVIRT__DISKS__:e133401bfdff6979f76d9544ec8a5529:/var/lib/libvirt/sanlock/e133401bfdff6979f76d9544ec8a5529:0 for 1,9,4218

[Patch] Libvirt - Fix locking for readonly devices
by David Weber
Hi,
I'm currently working on getting sanlock into Debian/Ubuntu.
While testing, I noticed that I wasn't able to add a readonly
or shared device: "internal error unsupported
configuration: Readonly leases are not supported".
After looking into the source, it seems to be the following
situation:
- Libvirt passes every device to the sanlock plugin, even if
it is readonly
- The sanlock plugin rejects to add a lease for the readonly
device, returning an error so the machine starts to fail
The attached patch rejects passing readonly and shared devices
to the lock-plugin so they shouldn't be a problem anymore.
Would this be an appropriated way to fix this problem? (I'm
neither experienced in libvirt nor C)
What seems odd to me is that Fedora either doesn't hit this
or nobody has ever reported it.
I'm not member of this list so please CC me.
Thanks!
Cheers,
David

Remove redundant arg to 'run_command'
Rename optarg to optionarg to avoid clashing with getopt.h
Disable the read_request method since it is unused
Add many more compiler warning flags & safety checks
Hard code a sector size of 512 if the lease volume is a regular file
Ensure libsanlock.so is built with debug/warning flags
