Cannot start VM: Bad volume specification
by Alan G 04 Mar '19

04 Mar '19

Hi, I performed the following: - 1. Shutdown VM. 2. Take a snapshot 3. Create a clone from snapshot. 4. Start the clone. Clone starts fine. 5. Attempt to delete snapshot from original VM, fails. 6. Attempt to start original VM, fails with "Bad volume specification". This was logged in VDSM during the snapshot deletion attempt. 2019-02-26 13:27:10,907+0000 ERROR (tasks/3) [storage.TaskManager.Task] (Task='67577e64-f29d-4c47-a38f-e54b905cae03') Unexpected error (task:872) Traceback (most recent call last): File "/usr/share/vdsm/storage/task.py", line 879, in _run return fn(*args, **kargs) File "/usr/share/vdsm/storage/task.py", line 333, in run return self.cmd(*self.argslist, **self.argsdict) File "/usr/lib/python2.7/site-packages/vdsm/storage/securable.py", line 79, in wrapper return method(self, *args, **kwargs) File "/usr/share/vdsm/storage/sp.py", line 1892, in finalizeMerge merge.finalize(subchainInfo) File "/usr/share/vdsm/storage/merge.py", line 271, in finalize optimal_size = subchain.base_vol.optimal_size() File "/usr/share/vdsm/storage/blockVolume.py", line 440, in optimal_size check = qemuimg.check(self.getVolumePath(), qemuimg.FORMAT.QCOW2) File "/usr/lib/python2.7/site-packages/vdsm/qemuimg.py", line 157, in check out = _run_cmd(cmd) File "/usr/lib/python2.7/site-packages/vdsm/qemuimg.py", line 426, in _run_cmd raise QImgError(cmd, rc, out, err) QImgError: cmd=['/usr/bin/qemu-img', 'check', '--output', 'json', '-f', 'qcow2', '/rhev/data-center/mnt/blockSD/024109d5-ea84-47ed-87e5-1c8681fdd177/images/f7dea7bd-04 6c-4923-b5a5-d0c1201607fc/ac540314-989d-42c2-9e7e-3907eedbe27f'], ecode=3, stdout={ "image-end-offset": 52210892800, "total-clusters": 1638400, "check-errors": 0, "leaks": 323, "leaks-fixed": 0, "allocated-clusters": 795890, "filename": "/rhev/data-center/mnt/blockSD/024109d5-ea84-47ed-87e5-1c8681fdd177/images/f7dea7bd-046c-4923-b5a5-d0c1201607fc/ac540314-989d-42c2-9e7e-3907eedbe27f", "format": "qcow2", "fragmented-clusters": 692941 } , stderr=Leaked cluster 81919 refcount=1 reference=0 Leaked cluster 81920 refcount=1 reference=0 Leaked cluster 81921 refcount=1 reference=0 etc..

Re: low power, low cost glusterfs storage

The problem is that anything on the budged doesn't have decent network + enough storage slots.

Cannot assign Network to Mellanox Interface
by cbop.mail＠gmail.com 02 Mar '19

02 Mar '19

Hello, I want to use my Infiniband Network for Storage Access, so I created a new network and tried to assign it to a host. When I do this, I get a success message but it's actually not assigned to my Infiniband NIC. I'm running the latest CentOS with the latest Mellanox OFED drivers and multiple Subnet Managers are running on the network. The NIC is a Mellanox ConnectX-2 VPI, set to Infiniband mode. I didnt't knew which logs to send, so when you need to look into a log, just tell me which one you need. I hope you can help me out. Roman Meusch

oVirt 4.3 and dual socket hosts : numad?
by Guillaume Pavese 02 Mar '19

02 Mar '19

Is it recommended to enable numad service for automatic NUMA memory optimization? I could not find any recommendation on that front for oVirt ; all benchmarks and documentation I could find are from around ~2015 I see that kernel autonuma balancing is on : cat /proc/sys/kernel/numa_balancing 1 Not sure which is better as of now.
