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
