Unallocated space on sdb ~ 363.6GB

Unallocated space on sda ~ 447.1GB (Full)

Create new partition on sdb (sdb6) and allocate remaining space to it

fdisk /dev/sdb

n

partition no. : default

First sector : default

Last sector : default

w (write to disk and exit)

Create partition on sda

fdisk /dev/sda

n

primary

default

Mirror sdb6 and sda1

mkfs.btrfs -f -m raid1 -d raid1 /dev/sdb6 /dev/sda1

Verify mirrored successfully

btrfs file usage /btrfs

"Device size" should be combined size of sdb6+sda1"

Make a mount point

mkdir /btrfs

Mount

mount /dev/sdb6 /btrfs

Add below to fstab which is used at reboot

mount /btrfs on sdb6 filesystem

/dev/sdb6 /btrfs btrfs defaults 0 0

Reboot to test fstab working

reboot

df -h #to verify mounted successfully

Or alternatively unmount and mount to test fstab working

umount /dev/sdb6

mount -a

./update.neosys0.sh

Run from nl20

./install.neosys1.on.lxd.sh

Run from new host server

To fix image upload issue (adlined)

Clear line 49 of hosts/adlined/work/system.cfg

edir hosts/adlined/work/system.cfg 49

ZoneEdit changes and test access

tmux

Done on nl20 install.tmux.general.sh install.tmux.neosys.sh

Data Comparison

If initial rsync (step 4) was done mid-day and if users are not active, then do AREV live to test copy and immediately do rsync and import_db so that you can compare exodus LIVE with AREV TEST.

Change letterhead

Change all company's letterhead to "THIS IS A TEST SYSTEM" (left) and "DO NOT DO LIVE WORK HERE" (right)

Enable emails

On screen 8, touch ~/hosts/<dbname>/work/live.txt to enable emails to users
