low power, low cost glusterfs storage
by Jonathan Baecker 04 Mar '19

04 Mar '19

Hello everybody! Does anyone here have experience with a cheap, energy-saving glusterfs storage solution? I'm thinking of something that has more power than a rasbian Pi, 3 x 2 TB (SSD) storage, but doesn't cost much more and doesn't consume much more power. Would that be possible? I know the "Red Hat Gluster Storage" requirements, but are they generally so high? Only a few VM images would have to be on it... Greetings Jonathan

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..

The problem is that anything on the budged doesn't have decent network + enough storage slots. Maybe a homemade workstation with AMD ryzen could do the trick - but this is way over the budged compared to raspberry Pi-s Best Regards, Strahil NikolovOn Mar 3, 2019 12:22, Jonathan Baecker <jonbae77(a)gmail.com> wrote: > > Hello everybody! > > Does anyone here have experience with a cheap, energy-saving glusterfs > storage solution?

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
