ECE install stuck

Dear Team,
My ECE installation is stuck for few hours at same state

I am using centos 7.6, kernel 3.10.0-957.12.2.el7.x86_64. I have followed all the installation steps.

Elastic Cloud Enterprise Installer

Start setting up a new Elastic Cloud Enterprise installation by installing the software on your first host.
This first host becomes the initial coordinator and provides access to the Cloud UI, where you can manage your installation.
To learn more about the options you can specify, see the documentation.

NOTE: If you want to add this host to an existing installation, please specify the --coordinator-host and --roles-token flags

-- Verifying Prerequisites --
Checking runner container does not exist... PASSED
Checking host storage root volume path is not root... PASSED
Checking host storage path is accessible... PASSED
Checking host storage path contents matches whitelist... PASSED
Checking Docker version... PASSED
Checking Docker file system... PASSED
Checking Docker network settings... PASSED
 - The installation can proceed with ICC enabled; however, we recommend turning off ICC (icc=false).
Checking Docker storage driver... PASSED
Checking whether 'setuser' works inside a Docker container... PASSED
Checking memory settings... PASSED
 - Option `--memory-settings` not used. Default memory settings might be insufficient for production use!
Checking runner ip connectivity... PASSED
Checking OS IPv4 IP forward setting... PASSED
Checking OS max map count setting... PASSED
Checking OS kernel version... PASSED
 - OS kernel version is 3.10.0-957.12.2.el7.x86_64 but we recommend 4.4.
Checking minimum required memory... PASSED
Checking OS kernel cgroup.memory... PASSED
 - OS setting 'cgroup.memory' should be set to cgroup.memory=nokmem
Checking OS minimum ephemeral port... PASSED
Checking OS max open file descriptors per process... PASSED
Checking OS max open file descriptors system-wide... PASSED
Checking OS file system and Docker storage driver compatibility... PASSED
Checking OS file system storage driver permissions... PASSED

After this nothing happens. Below are the other settings output

[elastic@localhost data1]# sudo cat /etc/systemd/system/docker.service.d/docker.conf
Description=Docker Service

ExecStart=/usr/bin/dockerd --data-root /data1/docker --storage-driver=overlay --bip=

[elastic@localhost data1]# id elastic
uid=1003(elastic) gid=1003(elastic) groups=1003(elastic),4(adm),10(wheel),11(cdrom),18(dialout),19(floppy),39(video),63(audio),1004(docker)
[elastic@localhost data1]# id docker
uid=1004(docker) gid=1004(docker) groups=1004(docker),10(wheel)

i have not changed the "--bip" details and kept as default.
Nothing is shown for below command

[root@localhost data1]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
[root@localhost data1]#

I am not able to do "ls" as well on the mount point

[elastic@localhost data1]# sudo ls -l /data1
ls: cannot access /data1: Input/output error

Why its stuck I dont know. Any pointers?

problem resolved by re-installing
