Hi, Which version of gluster you are using? You can find which file is that using the following command find <brickpath> -samefile <brickpath/.glusterfs/<first two bits of gfid>/<next 2 bits of gfid>/<full gfid> Please provide the getfatr output of the file which is in split brain. The steps to recover from split-brain can be found here,

I tried this already. 8><--- [root at glusterp2 fb]# find /bricks/brick1/gv0 -samefile /bricks/brick1/gv0/.glusterfs/ea/fb/eafb8799-4e7a-4264-9213-26997c5a4693 /bricks/brick1/gv0/.glusterfs/ea/fb/eafb8799-4e7a-4264-9213-26997c5a4693 [root at glusterp2 fb]# 8><--- gluster 4 Centos 7.4 8><--- df -h [root at glusterp2 fb]# df -h Filesystem

I tried looking for a file of the same size and the gfid doesnt show up, 8><--- [root at glusterp2 fb]# pwd /bricks/brick1/gv0/.glusterfs/ea/fb [root at glusterp2 fb]# ls -al total 3130892 drwx------. 2 root root 64 May 22 13:01 . drwx------. 4 root root 24 May 8 14:27 .. -rw-------. 1 root root 3294887936 May 4 11:07 eafb8799-4e7a-4264-9213-26997c5a4693 -rw-r--r--. 1 root

Whatever repair happened has now finished but I still have this, I cant find anything so far telling me how to fix it. Looking at http://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Features/heal-info-and-split-brain-resolution/ I cant determine what file? dir gvo? is actually the issue.

Hi experts, When I test lxc container with lxc-enter-namespace command, It reported an error as following: root@debian:~/github/libvirt# vir lxc-enter-namespace lxc --noseclabel /bin/df -hl error: Cannot get namespaces for 3145: Function not implemented It seems that setns is not supported by my kernel. But from the following info, It seemed the reason is just libvirt/autoconf doesn't

Hi, I have 4 nodes, so a quorum would be 3 of 4. The Q is I suppose why does the documentation give this command as an example without qualifying it? SO I am running the wrong command?

Hi, With replica 2 volumes one can easily end up in split-brains if there are frequent disconnects and high IOs going on. If you use replica 3 or arbiter volumes, it will guard you by using the quorum mechanism giving you both consistency and availability. But in replica 2 volumes, quorum does not make sense since it needs both the nodes up to guarantee consistency, which costs availability. If

Hi, I have 3 Centos7.4 machines setup as a 3 way raid 1. Due to an oopsie on my part for glusterp1 /bricks/brick1/gv0 didnt mount on boot and as a result its empty. Meanwhile I have data on glusterp2 /bricks/brick1/gv0 and glusterp3 /bricks/brick1/gv0 as expected. Is there a way to get glusterp1's gv0 to sync off the other 2? there must be but, I have looked at the gluster docs and I

Show us output from: gluster v status It should be easy to fix. Stop gluster daemon on that node, mount the brick, start gluster daemon again. Check: gluster v status Does it show the brick up?
