Thanks for the suggestion, this solved it for us, and we probably found the cause as well. We had performance co-pilot running and it was continously enabling profiling on volumes... We found the reference to the node that had the lock, and restarted glusterd on that node, and all went well from there on.

Hi This is gluster 3.8.4. Volume options are out of the box. Sharding is off (and I don't think enabling it would matter) I haven't done much performance tuning. For one thing, using a simple script that just creates files I can easily flood the network, so I don't expect a performance issue. The problem we see is that after a certain time the fuse clients completely stop accepting

Hi all, I am trying to do trivial things, like setting quota, or just querying the status and keep getting "Another transaction is in progres for <some volume>" These messages pop up, then disappear for a while, then pop up again... What do these messages mean? How do I figure out which "transaction" is meant here, and what do I do about it? Krist -- Vriendelijke

Hi all, A few questions. - Is POSIX locking enabled when using the native client? I would assume yes. - What other settings/tuneables exist when it comes to file locking?

Hi Krist, What are your volume options on that setup? Have you tried tuning it for the kind of workload and files size you have? I would definitely do some tests with feature.shard=on/off first. If shard is on, try playing with features.shard-block-size. Do you have jumbo frames (MTU=9000) enabled across the switch and nodes? if you have concurrent clients writing/reading, it could be beneficial

Hi all, I'm doing some performance test... If I test a simple sequential write using dd I get a thorughput of about 550 Mb/s. When I do a sequential write test using sysbench this drops to about 200. Is this due to the way sysbench tests? Or has in this case the performance of sysbench itself become the bottleneck? Krist -- Vriendelijke Groet | Best Regards | Freundliche Gr??e |

Hello, Is it possible to set up a Heketi Managed gluster cluster in one datacenter, and then have geo replication for all volumes to a second cluster in another datacenter? I've been looking at that, but haven't really found a recipe/solution for this. Ideally what I want is that when a volume is created in cluster1, that a slave volume is automatically created in cluster2, and

Hello, I have a gluster cluster with 4 nodes, that is managed using heketi. I want to test the removeal of one node. We have several volumes on it, some with rep=2, others with rep=3. I get the following error: [root at CTYI1458 .ssh]# heketi-cli --user admin --secret "******" node remove 749850f8e5fd23cf6a224b7490499659 Error: Failed to remove device, error: Cannot replace brick

Hi all, I usualy advise clients to use the native client if at all possible, as it is very robust. But I am running in to problems here. In this case the gluster system is used to store video streams. Basicaly the setup is the following: - A gluster cluster of 3 nodes, with ample storage. They export several volumes. - The network is 10GB, switched. - A "recording server" which

Hello, I have the following problem: On a solaris 10 machine, with 5 "zones" there is a process that is talking to the wrong db server. I need to find out which process this is, so I can analize this further. I have tried to doing this using tcpsnoop from the DTrace toolkit, but without success. This is what I''ve done. First I started tcpsnoop, dumping it''s output

Hi I have some problems with my vpn. Im running version 1.1pre15 on all nodes. I have four nodes in my network. Node1 -> connects to Node2 Node2 -> connects to Node1 Node3 -> connects to Node1 and Node2 Node4 -> connects to Node1 and Node2 The problem is the connection between Node3 and Node4. The traffic is going via Node1 and Node2. Its unstable. package drops almost all the time

Dear All, Yesterday evening or cluster has stopped. Two of our nodes tried to take the resource from each other, they haven''t seen the other side, if I saw well. I stopped heartbeat, resources, start it again, and back to online, worked fine. This morning I saw this in logs: Feb 22 03:25:07 node4 kernel: Lustre: 7:0:(linux-debug.c:98:libcfs_run_upcall()) Invoked LNET upcall

What I want to ask you is: - What do you think about it? - Did you find it useful? - Do you have any advices?

Hello, We have a four-node RHEL4 RAC cluster running OCFS2 version 1.2.8-2 and the 2.6.9-67.0.4hugemem kernel. The cluster has been really stable since we upgraded to 1.2.8-2 early this year, but this morning, one of the nodes fenced and rebooted itself, and I wonder if anyone could glance at the below remote syslogs and offer an opinion as to why. First, here's the output of

Hi, I'm sometimes getting a failure of connecting 2 nodes when Tinc is started and configured in a LAN. In the logs, there are some unexpected dropped packets with very high or negative seq. I can reproduce this issue ~2% of the time. When this happens, the 2 nodes can no longer ping or ssh each other through the tunnel interface but using eth0 works fine. The connection can recover after at

Hi all, I am currently deploying tinc as an alternative to OpenVPN. My setup includes a lot of nodes and some of them are sitting together behind the same router on the same network segment. (E.g. connected to the same switch.) I noticed, that those nodes do never talk directly to each other via their private ip-addresses, but instead use the NATed address they got from the router.

That's what UCI is trying to do. I'm hoping for just a simple unified Ogg interface for the audio codecs that Ogg supports. -dwh- On 31 Jan 2003, Csillag Krist?f wrote: > Here is what I imagined (just vague thoughts, nothing polished): > > Let's suppose we have a hypotetical library called > "Free Universal Codec Kit" - ..um...well..
