hidden:Backup with Relax-and-Recover

IBM,Jonathan had installed Relax-and-Recover an all HPSS machines but it has been configured only on HPSS Test Core and HPSS Test Mover
[root@hpsstmvr etc]# /usr/sbin/rear -V
Relax-and-Recover 1.17.1 / Git
This version is not in the git repository any longer
Installed by IBM, Jonathan 
I let this version because it is the version we already made a recovery from.
Should we replace it?

Dorin deployed it on all HPSS machines and installed and configured it on all front end machines on 11.07.2016
Dorin changed the mount point for ReaR backups 
from 
nfs://lsmb02.lsdf.kit.edu/gpfs/nfsshares/scc/hpss/rear/ 
to
nfs://hpa.lsdf.kit.edu/export/hpa/ReaR_Backups/
Reasons:
since the hpss mover 4 has no IP network 141 it is not able to mount the gpfs file system
ReaR makes every day an bare metal backup and keeps only one version on the mounted nfs file system
a TSM backup will be configured for hpa and the "rear backups" will be archived in tsm so that more versions will be kept 

On all machines
ReaR mounts the nfs file system at the running time on /mnt/ba_os_image/
ReaR configuration file /etc/rear/local.conf
Rear log: /var/log/rear/rear-HOSTNAME.log
ReaR default configuration file: /usr/share/rear/conf/default.conf

IMPORTANT
According to relax-and-recover documentation (see /usr/share/rear/conf/default.conf)
# Exclude LVM2 volume groups. This will automatically exclude also the creation of the corresponding
# physical and logical volumes that belong to the excluded volume group.
#
# NOTE: YOU MUST ALSO EXCLUDE THE CORRESPONDING MOUNTPOINTS IN EXCLUDE_MOUNTPOINTS (see above)
#       OTHERWISE THE RECOVERY ***WILL*** TRY TO RECREATE THE FILESYSTEMS ONTO NON-EXISTING LVs

1. Configure Relax-and-recover on a HPSS mover

1.1. check active vg:

root@hpssmvr01 rear]# vgs
VG      #PV #LV #SN Attr   VSize  VFree 
hpss_vg   1   2   0 wz--n- 64.00g 58.00g

1.2. check LV

root@hpssmvr01 rear]# lvs
LV       VG      Attr       LSize Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
hpss_src hpss_vg -wi-ao---- 4.00g                                                    
varhpss  hpss_vg -wi-ao---- 2.00g 

1.3. check the mount points of LV

mount   
/dev/mapper/hpss_vg-varhpss on /varhpss type ext4 (rw)
/dev/mapper/hpss_vg-hpss_src on /hpss_src type ext4 (rw)

1.4. edit /etc/rear/local.conf

cat /etc/rear/localconf
OUTPUT=ISO
BACKUP=NETFS
BACKUP_URL="nfs://lsmb02.lsdf.kit.edu/gpfs/nfsshares/scc/hpss/rear/"
EXCLUDE_MOUNTPOINTS=( '/hpss_src' '/varhpss' '/kdumps' )
EXCLUDE_VG=( 'hpss_vg')

1.4. edit crontab

crontab -l
system backup
0 3 * * * /usr/sbin/rear mkbackup

2. Configure Relax-and-Recover on HPSS core

2.1. check active vg:

2.4.3. On HPSS Core 02

just copy it from active core
the file systems are not mounted on stand by core but the vg, lv and the mount points are here

To be tested if there is any problem with active core and standby core (write the result here)

2.5. edit crontab

#system backup
0 1 * * * /usr/sbin/rear mkbackup

IMPORTANT
ReaR generates a backup directory with the name returned by hostname. The active core hostname is hpsscr regardless of which host is running on.
An appropriate solution has to be found

3. Configure Relax-and-Recover on front end machines

3.1. archive-sftp-01/02 archive-gftp-fuse(alias bwdahub)

Install needed packages:
yum install genisoimage-1.1.9-12.el6.x86_64
yum install nfs-utils.x86_64
yum install syslinux-nonlinux.noarch 
cd /root/Software/ReaR
rpm -ivh rear-1.17.1-1.el6.noarch.rpm
Make nfs mount point:
mkdir /mnt/ba_os_image
Edit crontab:
#system backup
0 3 * * * /usr/sbin/rear mkbackup
