I have install and configure on two server CentOS8 glusterfs in replica mode in this manner:

dnf install CentOS-release-gluster -y
dnf install glusterfs-server glusterfs glusterfs-fuse -y
systemctl enable –now glusterd
gluster peer probe virt1
gluster peer status
sh creavolume.sh gfsvol1 301G /gfsvol1 xfs
# NOTE: this is a my shell script to create fs on lvm
mkdir /gfsvol1/brick1
gluster pool list
gluster volume create gfsvol1 replica 2 virt1:/gfsvol1/brick1
virt2:/gfsvol1/brick1 force
gluster volume start gfsvol1
gluster volume info gfsvol1
gluster volume status gfsvol1
gluster volume heal gfsvol1
# add to /etc/fstab
vi /etc/fstab
virt1:/gfsvol2 /virt-gfs glusterfs defaults,noatime,_netdev 0
0
mkdir /virt-gfs
mount -a

All work fine but when I start or restart all server together glusterd server start but if I try mount the volume, gluster is not working.

At this point if I restart the glusterd service and run “mount -a” all work fine.

Seem is a boot network problem

Then I have try modify glusterd.service with

$ sudo systemctl edit glusterd.service –full

And modify the unit in this way:

#old
< After=network.target
< Before=network-online.target #new > After=network.target network-online.target
> #Before=network-online.target

Now all work fine, mostly when I start or restart all server together.

There is another solution or this is a Bug?

Many thanks for your suggest
