This logfile didn't have any logs about heal. Could you find the same file on the other node as well and attach it to the mail-thread? We should also see the mount logs once to confirm replication did something or not. Otherwise we should see the brick logs. Instead of checking it iteratively, could you tar /var/log/glusterfs on both the nodes and give links to these files so that we can download and check what might have happened?--On Thu, Sep 20, 2018 at 2:00 PM Johan Karlsson <Johan.Karlsson@xxxxxx> wrote:I understand that a 2 way replica can require some fiddling with heal, but how is it possible that all data just vanished, even from the bricks?

Yes indeed.

+Pranith. +Ravi.
Not sure whether 2 way replication has caused this. From what I understand we need either 3 way replication or arbiter for correct resolution of heals.

I have two servers setup with glusterFS in replica mode, a single volume exposed via a mountpoint. The servers are running Ubuntu 16.04 LTS
After a package upgrade + reboot of both servers, it was discovered that the data was completely gone. New data written on the volume via the mountpoint is replicated correctly, and gluster status/info commands states that everything is ok (no split brain scenario or any healing needed etc). But the previous data is completely gone, not even present on any of the bricks.
The following upgrade was done:
glusterfs-server:amd64 (4.1.0-ubuntu1~xenial3 -> 4.1.4-ubuntu1~xenial1)
glusterfs-client:amd64 (4.1.0-ubuntu1~xenial3 -> 4.1.4-ubuntu1~xenial1)
glusterfs-common:amd64 (4.1.0-ubuntu1~xenial3 -> 4.1.4-ubuntu1~xenial1)
The logs only show that connection between the servers was lost, which is expected.
I can't even determine if it was the package upgrade or the reboot that caused this issue, but I've tried to recreate the issue without success.
Any idea what could have gone wrong, or if I have done some wrong during the setup. For reference, this is how I've done the setup:
---
Add a separate disk with a single partition on both servers (/dev/sdb1)
Add gfs hostnames for direct communication without DNS, on both servers:
/etc/hosts
192.168.4.45 gfs01
192.168.4.46 gfs02
On gfs01, create a new LVM Volume Group:
vgcreate gfs01-vg /dev/sdb1
And on the gfs02:
vgcreate gfs02-vg /dev/sdb1
Create logical volumes named "brick" on the servers:
gfs01:
lvcreate -l 100%VG -n brick1 gfs01-vg
gfs02:
lvcreate -l 100%VG -n brick2 gfs02-vg
Format the volumes with ext4 filesystem:
gfs01:
mkfs.ext4 /dev/gfs01-vg/brick1
gfs02:
mkfs.ext4 /dev/gfs02-vg/brick2
Create a mountpoint for the bricks on the servers:
gfs01:
mkdir -p /glusterdata/brick1
gds02:
mkdir -p /glusterdata/brick2
Make a permanent mount on the servers:
gfs01:
/dev/gfs01-vg/brick1 /glusterdata/brick1 ext4 defaults 0 0
gfs02:
/dev/gfs02-vg/brick2 /glusterdata/brick2 ext4 defaults 0 0
Mount it:
mount -a
Create a gluster volume mount point on the bricks on the servers:
gfs01:
mkdir -p /glusterdata/brick1/gvol0
gfs02:
mkdir -p /glusterdata/brick2/gvol0
>From each server, peer probe the other one:
gluster peer probe gfs01
peer probe: success
gluster peer probe gfs02
peer probe: success
>From any single server, create the gluster volume as a "replica" with two nodes; gfs01 and gfs02:
gluster volume create gvol0 replica 2 gfs01:/glusterdata/brick1/gvol0 gfs02:/glusterdata/brick2/ gvol0
Start the volume:
gluster volume start gvol0
On each server, mount the gluster filesystem on the /filestore mount point:
gfs01:
mount -t glusterfs gfs01:/gvol0 /filestore
gfs02:
mount -t glusterfs gfs02:/gvol0 /filestore
Make the mount permanent on the servers:
/etc/fstab
gfs01:
gfs01:/gvol0 /filestore glusterfs defaults,_netdev 0 0
gfs02:
gfs02:/gvol0 /filestore glusterfs defaults,_netdev 0 0
