Hello Ayal Baron, Bala.FA, Saggi Mizrahi, Dan Kenigsberg, I'd like you to do a code review. Please visit http://gerrit.ovirt.org/18355 to review the following change. Change subject: gluster: Setup and verify ssl connection between nodes. ...................................................................... gluster: Setup and verify ssl connection between nodes. This will be used in geo-replication session creation. Because, there should be password-less ssh access between at least one node of master volume and one node of slave volume before creating geo-replication session. Below new verbs are added *glusterValidateSshConnection *glusterSetupSshConnection Change-Id: Ia6f040b1343998de4f8e28419c63e380240368db Signed-off-by: Bala.FA <barumuga(a)redhat.com> Signed-off-by:

Change in vdsm[master]: vm: Require format attribute for drives
by Nir Soffer 13 Aug '15

13 Aug '15

Nir Soffer has uploaded a new change for review. Change subject: vm: Require format attribute for drives ...................................................................... vm: Require format attribute for drives We have seen sampling errors where a drive has no "format" attribute. These errors spam the system logs, and does not help to debug the real issue - why the required format attribute is not set? This patch ensure that a drive cannot be created without a format attribute, avoding log spam by sampling errors, and hopefully revealing the real reason for this bug. One broken test creating a drive without a format was fixed and new test ensure that creating drive without a format raises.

Change in vdsm[master]: resourceManager: Keep resource state if registerResource fails
by Nir Soffer 13 Aug '15

13 Aug '15

Nir Soffer has uploaded a new change for review. Change subject: resourceManager: Keep resource state if registerResource fails ...................................................................... resourceManager: Keep resource state if registerResource fails Previous code was increasing resource activeUsers counter, but exceptions raised after that caused the method to fail, leaving a locked resources that nobody can release. Such locked resource may lead to failure of any pool operation, making the host non-operational, and requiring a restart of vdsm. The failure in the field was caused by Python logging bug, raising OSError when message was logged when log file was rotated. However, such failure can happen everywhere, and locking code must be written in such way that failure would never leave a resource locked. This patch ensure that resource is added and activeUsers counter is increased only if everything else was fine. Since simulating logging error is hard, the tests monkeypatch the RequestRef class to simulate a failure. This is little ugly, depending on internal implementation detail, but I could not find a cleaner way.

Change in vdsm[ovirt-3.3]: vm: Continue to sample after errors

Nir Soffer has uploaded a new change for review. Change subject: vm: Continue to sample after errors ...................................................................... vm: Continue to sample after errors When vm is running, we monitor disk usage, and if the disk becomes too full, we extend the disk. This avoid pausing of the vm after io errors. However, when sampling vm with multiple disks, an error when sampling one disk exit the sampling function and skip the next disks, making this machnisim useless. This patch logs exceptions raised when sampling one disk and continue to sample others. This patch is for ovirt-3.3.1 only - master patch must be different because of recent refactoring in this area.
