<br>
I am doing some tests with GlusterFS 4.0 and I can't seem to solve some SSL/TLS issues. I am trying to set up a 2 node replicated gluster volume with SSL/TLS. For this setup, I use 3 KVM VMs (2 storage nodes + 1 client node). For the networking part, I use a dedicated private LAN for the KVM VMs. Each VM is able to ping the other, so there's no problem with the connectivity.<br>
<br>
To try to make the procedure I used as clear as possible, I will put all commands in chronological order:<br>
<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
1. First, I update the systems, install ntp and then reboot:<br>
<br>
yum update<br>
<br>
yum install ntp<br>
<br>
systemctl status ntpd<br>
systemctl start ntpd<br>
systemctl enable ntpd<br>
systemctl status ntpd<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
<br>
2. I use a separate partition within the two VM storage nodes. Each of the two nodes see the separate partition as /dev/sdb. After creating a thinly provisioned LV on each of the two nodes, I create an XFS filesystem on them:<br>
<br>
<br>
pvcreate /dev/sdb1<br>
<br>
vgcreate -s 32M vg_glusterfs /dev/sdb1<br>
<br>
lvcreate -L 20G --thinpool glusterfs_thin_pool vg_glusterfs<br>
<br>
lvcreate -V 15G --thin -n glusterfs_thin_vol1 vg_glusterfs/glusterfs_thin_po<wbr>ol<br>
<br>
mkfs.xfs -i size=512 /dev/vg_glusterfs/glusterfs_th<wbr>in_vol1<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
<br>
3. On each node, I configured the brick data partition and added the following to /etc/fstab:<br>
<br>
mkdir /data<br>
<br>
echo "/dev/vg_glusterfs/glusterfs_t<wbr>hin_vol1 /data xfs defaults 1 2" >> /etc/fstab<br>
<br>
mount -a<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
4. After mounting the volume, I see the following in df -Th, which is correct:<br>
<br>
[root@gluster1 brick1]# df -Th<br>
Filesystem Type Size Used Avail Use% Mounted on<br>
/dev/sda1 ext4 46G 1.4G 42G 4% /<br>
devtmpfs devtmpfs 3.9G 0 3.9G 0% /dev<br>
tmpfs tmpfs 3.9G 0 3.9G 0% /dev/shm<br>
tmpfs tmpfs 3.9G 8.6M 3.9G 1% /run<br>
tmpfs tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup<br>
tmpfs tmpfs 783M 0 783M 0% /run/user/0<br>
/dev/mapper/vg_glusterfs-glust<wbr>erfs_thin_vol1 xfs 15G 34M 15G 1% /data<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
5. Create specific volume dirs on all storage nodes:<br>
<br>
<br>
mkdir -pv /data/glusterfs/${HOSTNAME%%.*<wbr>}/vol01<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
6. Add entries in /etc/hosts:<br>
<br>
vim /etc/hosts<br>
<br>
192.168.10.233 gluster1<br>
192.168.10.234 gluster2<br>
192.168.10.237 gluster-client<br>
<br>
==============================<wbr>=======================<br>
<br>
7. Install gluster from the CentOS SIG:<br>
<br>
<br>
yum search centos-release-gluster<br>
yum install centos-release-gluster40<br>
<br>
<br>
yum install glusterfs-server<br>
<br>
==============================<wbr>=======================<br>
<br>
8. Set up TLS/SSL encryption on all nodes and clients (gluster1, gluster2, gluster-client):<br>
<br>
openssl genrsa -out /etc/ssl/glusterfs.key 2048<br>
<br>
In gluster1 node:<br>
openssl req -new -x509 -key /etc/ssl/glusterfs.key -subj "/CN=gluster1" -out /etc/ssl/glusterfs.pem<br>
In gluster2 node:<br>
openssl req -new -x509 -key /etc/ssl/glusterfs.key -subj "/CN=gluster2" -out /etc/ssl/glusterfs.pem<br>
In gluster-client node:<br>
openssl req -new -x509 -key /etc/ssl/glusterfs.key -subj "/CN=gluster-client" -out /etc/ssl/glusterfs.pem<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
9. On another box, I concatenate all of the .pem certificates into a .ca file.<br>
<br>
Bring all .pem files locally:<br>
<br>
scp gluster1:/etc/ssl/<a href="http://glusterfs.pe">glusterfs.pe</a><wbr>m gluster01.pem<br>
scp gluster2:/etc/ssl/<a href="http://glusterfs.pe">glusterfs.pe</a><wbr>m gluster02.pem<br>
scp gluster-client:/etc/ssl/gluste<wbr>rfs.pem gluster-client.pem<br>
<br>
For storage nodes, I concatenate all .pem certificates (including the client's .pem):<br>
<br>
cat gluster01.pem gluster02.pem gluster-client.pem > <a href="http://glusterfs-nodes.ca" rel="noreferrer" target="_blank">glusterfs-nodes.ca</a><br>
<br>
For server clients:<br>
<br>
cat gluster01.pem gluster02.pem > <a href="http://glusterfs-client.ca" rel="noreferrer" target="_blank">glusterfs-client.ca</a><br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
<br>
10. Put <a href="http://glusterfs-nodes.ca" rel="noreferrer" target="_blank">glusterfs-nodes.ca</a> file on all the storage nodes (this includes storage nodes .pem + client's .pem):<br>
<br>
scp <a href="http://glusterfs-nodes.ca" rel="noreferrer" target="_blank">glusterfs-nodes.ca</a> gluster1:/etc/ssl/<a href="http://glusterfs.ca" rel="noreferrer" target="_blank">glusterfs.ca</a><br>
scp <a href="http://glusterfs-nodes.ca" rel="noreferrer" target="_blank">glusterfs-nodes.ca</a> gluster2:/etc/ssl/<a href="http://glusterfs.ca" rel="noreferrer" target="_blank">glusterfs.ca</a><br>
<br>
Put <a href="http://glusterfs-client.ca" rel="noreferrer" target="_blank">glusterfs-client.ca</a> file on all the storage nodes (this includes only storage nodes .pem):<br>
<br>
scp <a href="http://glusterfs-client.ca" rel="noreferrer" target="_blank">glusterfs-client.ca</a> gluster-client:/etc/ssl/<a href="http://glusterfs.ca" rel="noreferrer" target="_blank">gluste<wbr>rfs.ca</a><br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
<br>
11. Enable management encryption on each node (command ran on gluster1, gluster2, gluster-client):<br>
<br>
<br>
touch /var/lib/glusterd/secure-acces<wbr>s<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
<br>
12. Start, enable and check status of glusterd on gluster1 and gluster2:<br>
<br>
systemctl start glusterd<br>
systemctl enable glusterd<br>
systemctl status glusterd<br>
<br>
==============================<wbr>=======================<br>
<br>
13. Configure trusted storage pool (TSP):<br>
<br>
>From gluster1:<br>
<br>
<br>
gluster peer status<br>
<br>
<br>
gluster peer probe gluster2<br>
<br>
==============================<wbr>=======================<br>
<br>
14. Create the replicated gluster volume but don't start it:<br>
<br>
<br>
gluster volume create vol01 replica 2 transport tcp gluster1:/data/glusterfs/glust<wbr>er1/vol01/brick1 gluster2:/data/glusterfs/glust<wbr>er2/vol01/brick1<br>
<br>
==============================<wbr>=======================<br>
<br>
<br>
15. Setup SSL/TLS access to the volume:<br>
<br>
gluster volume set vol01 auth.ssl-allow 'gluster01,gluster02,gluster-c<wbr>lient'<br>
<br>
<br>
gluster volume set vol01 client.ssl on<br>
gluster volume set vol01 server.ssl on<br>
<br>
gluster volume set vol01 network.ping-timeout "5"<br>
<br>
gluster volume start vol01<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
<br>
16. Mount the volume on gluster-client:<br>
<br>
mount -t glusterfs gluster1:/vol01 /mnt<br>
<br>
<br>
After mounting the volume, df -h has the correct output:<br>
<br>
[root@gluster-client mnt]# df -h<br>
Filesystem Size Used Avail Use% Mounted on<br>
/dev/sda1 48G 36G 9.3G 80% /<br>
devtmpfs 1.9G 0 1.9G 0% /dev<br>

gluster1:/vol01 15G 187M 15G 2% /mnt<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
17. If I try to copy an archive, it throws an error after transferring part of the file and the /mnt folder becomes inaccessible for a while:<br>
<br>
[root@gluster-client mnt]# cp /root/mybee.tar.gz /mnt/<br>
cp: error writing ‘/mnt/mybee.tar.gz’: Transport endpoint is not connected<br>
cp: failed to extend ‘/mnt/mybee.tar.gz’: Transport endpoint is not connected<br>
cp: failed to close ‘/mnt/mybee.tar.gz’: Transport endpoint is not connected<br>
[root@gluster-client mnt]# ll /mnt<br>
ls: cannot open directory .: Transport endpoint is not connected<br>
<br>
<br>
==============================<wbr>=======================<br>
<br>
This is the log from gluster-client for the mnt mountpoint (mnt.log):<br>

Can anyone point me in the right direction? What am I doing wrong? The mount works fine until I try to copy an archive, multiple smaller files or a bigger file on it (meaning it shows correctly in df -Th and I can create several files with "touch file1 file2..."). Basically, after any data transfer, I get these errors.<br>
<br>
<br>
I followed the indications from the redhat page:<br>
<br>
<a href="https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.1/html/administration_guide/chap-network_encryption" rel="noreferrer" target="_blank">https://access.redhat.com/docu<wbr>mentation/en-us/red_hat_gluste<wbr>r_storage/3.1/html/administrat<wbr>ion_guide/chap-network_<wbr>encryption</a><br>
<br>
UPDATE 1:<br>
I tried doing the exact same steps in Gluster 3.12 and had no problem. The steps worked and SSL/TLS was enabled. There was no transport error or anything and I also checked if SSL/TLS was enabled. Afterwards, I also tried with the new release 4.1 and the problem persists (same error with "Transport endpoint is not connected").<br>
Let me know if you need any other info. Any help is much appreciated.<br>
<br>
Thank you.<br>
