Re: Announcing Gluster release 4.0.1 (Short Term Maintenance)

[Thing <thing.thing@xxxxxxxxx>]

Hi,

Thanks, if anyone has the time could you review what I did?

I wrote up the process I did as follows.

Did I do anything wrong? have I missed anything?

Not sure firewall is 100% right.

(note I was recovering a brick from a previous ovirt/gluster 3.x install and wanted to keep the data hence the lvm2 stuff)

4.10.4Gluster 4.0

https://wiki.centos.org/HowTos/GlusterFSonCentOS#head-338b2d9d4c8a798ed7444f4f356c2a67ae8f7dc5

• Make sure the servers point at the internal DNS servers 192.168.1.241 and 192.168.1.104 and that domain and search lines are present

• Setup each in forward and reverse DNS

• Setup the servers in /etc/hosts

192.168.1.31    glusterp1.graywitch.co.nz       glusterp1
192.168.1.32    glusterp2.graywitch.co.nz       glusterp2
192.168.1.33    glusterp3.graywitch.co.nz       glusterp3

Install EPEL

• yum install http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Install Gluster 4.0

https://wiki.centos.org/SpecialInterestGroup/Storage

https://wiki.centos.org/SpecialInterestGroup/Storage/gluster-Quickstart

• yum install centos-release-gluster40

• mkdir -p /bricks/brick1

• Either create a new volume group, or recover esisting group.

  • To recover, run pvs and lvs  note the volume group and run vgchange,

vgchange -a y  vg-gluster-prod1

• add to /etc/fstab,

/dev/vg-gluster-prod1/gluster-prod1  /bricks/brick1 xfs defaults 1 2

• Setup the servers in DNS

• yum install glusterfs-server

• Start the gluster service,

  • systemctl enable glusterd

  • systemctl start glusterd

  • systemctl status glusterd

• Now we need to set the firewall

• Run, firewall-cmd –state it should reply “running”

  • firewall-cmd --add-service=nfs --add-service=samba --add-service=samba-client –permanent

  • firewall-cmd --add-port=111/tcp --add-port=139/tcp --add-port=445/tcp --add-port=965/tcp –add-port=2049/tcp

  • firewall-cmd --zone=public --add-rich-rule='rule family="ipv4" source address="192.168.1.31" accept'

  • firewall-cmd --zone=public --add-rich-rule='rule family="ipv4" source address="192.168.1.32" accept'

  • firewall-cmd --zone=public --add-rich-rule='rule family="ipv4" source address="192.168.1.33" accept'

  • firewall-cmd --add-port=24007/tcp --add-port=24008/tcp –permanent

  • firewall-cmd --add-port=24009/tcp --permanent

  • firewall-cmd --reload

• yum -y install nmap to allow troubleshooting

• setup the gluster volume,

  • gluster volume create gv0 replica 3 glusterp1:/bricks/brick1/gv0 glusterp2:/bricks/brick1/gv0 glusterp3:/bricks/brick1/gv0

• Start the volume,

  • gluster volume start gv0

• check the volume

  • gluster volume info

  • mkdir /gv0

  • mount -t glusterfs glusterp1:/gv0 /gv0

• test with, df -h
