Hi devs, I''ve been using btrfs on my file server since 2.6.32 and after upgrading to .33 I noticed that rebalancing took way longer than before. I have a 5 disk array used for a btrfs md setup, different hard drive sizes, brands, and interfaces. The last time I rebalanced I was using about 800GB of space on the 4.6TB array, and I started before I went to sleep and it was done when I woke up. I''m...

Hello everyone, I have problem rebalancing Gluster volume. Gluster version is 3.7.3. My 1x3 replicated volume become full, so I've added three more bricks to make it 2x3 and wanted to rebalance. But every time I start rebalancing, it fails immediately. Rebooting Gluster nodes doesn't help. # gluster volume rebalance gsae_artifa...

Hello, I'm having trouble migrating data from 1 removed replica set to another active one in a dist replicated volume. My test scenario is the following: - create set (A) - create a bunch of files on it - add another set (B) - rebalance (works fine) - remove-brick A - rebalance (doesn't rebalance - ran on one brick in each set) The doc seems to imply that it is possible to remove bricks and rebalance afterwards, is this incorrect ? Or should I maybe use replace-brick instead for this ? Thanks a lot, Vincent

Hi I have a five node 300 TB distributed gluster volume with zero replication. I am planning to add two more servers which will add around 120 TB. After fixing the layout, can I rebalance the volume while clients are online and accessing the data? Thanks Kashif -------------- next part -------------- An HTML attachment was scrubbed...

Are you planning to run a fix-layout first and then a rebalance after that? How full are your existing bricks? Regards, Nithya > Thanks > > Kashif > > __________________________________...

I already posted this in the thread "ENOSPC with mkdir and rename", but now I have a device with 100GB unallocated on the "btrfs fi sh" output, and when I run a rebalance of the form: > btrfs filesystem balance start -dusage=50 -musage=10 "$mount" I get more than 75 of such stack traces contaminating the klog. I've put some of them up in a gist here: https://gist.github.com/pwaller/1df8a7efc2f10343f2e3 and one of them is reproduced below. Is thi...

Hi Nithya, I see index in context: [2017-07-07 10:07:18.230202] E [MSGID: 106062] [glusterd-utils.c:7997:glusterd_volume_rebalance_use_rsp_dict] 0-glusterd: failed to get index I wonder if there is anything I can do to fix it. I was trying to strace gluster process but still have no clue what exactly is gluster index.

...s, we have another preview release for GlusterD-2.0. The highlights for this release are, - GD2 now uses an auto scaling etcd cluster, which automatically selects and maintains the required number of etcd servers in the cluster. - Preliminary support for volume expansion has been added. (Note that rebalancing is not available yet) - An end to end functional testing framework is now available - And RPMs are available for Fedora >= 25 and EL7. This release still doesn't provide a CLI. The HTTP ReST API is the only access method right now. Prebuilt binaries are available from [1]. RPMs have bee...

Just so I know. Is it correct to assume that this corruption issue is ONLY involved if you are doing rebalancing with sharding enabled. So if I am not doing rebalancing I should be fine? -bill On 10/3/2017 10:30 PM, Krutika Dhananjay wrote: > > > On Wed, Oct 4, 2017 at 10:51 AM, Nithya Balachandran > <nbalacha at redhat.com <mailto:nbalacha at redhat.com>> wrote: > > &gt...

...remove the failing disk, mount with -o degraded and every works fine. The day later I decide to use an usb drive to temporarily work as the secondary copy. Now the usb drive had some GB less then the old drive, so I add the drive plus a small partition of another disk to avoid space problems on the rebalancing. I start the "btrfs device delete missing" and btrfs starts rebalancing the drive. After a while I get Sep 30 11:35:31 tambura kernel: [264654.275303] kernel BUG at fs/btrfs/relocation.c:1055!

...to add extra redundancy. In the end, I want to have the following done: Add a peer to the cluster Add 2 bricks to the cluster (one on server A and one on SERVER C) to the existing volume Add 2 bricks to the cluster (one on server B and one on SERVER C) to the existing volume After that, I need to rebalance all the data between the bricks... Is this config supported? Is there something I should be careful before I do this? SHould I do a rebalancing before I add the 3 set of disks?

...S3 and MS4 are pod2 and are configured with replication between them and host users 501-1000. Ideally the active connections in pod1 would be split 50/50 between MS1 and MS2. When maintenance is performed obviously all active connections/users would be moved to the other node in the pod and then rebalanced once maintenance is completed. I'm not sure if I need to use both the proxy and director, or just one or the other? If both then what is the proper path, from a network perspective? I like the functionality director provides, being able to add/remove servers on the fly and adjust connecti...
