Screen / Monitor Resolution
-First problem after installing nvidia driver was 640x480 resolution. Eventually fixed this with
sudo displayconfig-gtk
and changing the screen to LCD 1024x768. Prior to this I installed envyng-gtk to get the latest nvidia driver, but I probably didn't need to.
VMware Server
Installed VMware server with serial
VMware Server 2 for Linux A0425-FF72N-U3436-4CPCX
RAID / RAID5
First tried using evms as used previously to create/maintain the RAID. This broke everything, and I had to remove/uninstall theis from the root prompt on the recovery console.
Successfully recreated the RAID installing and using mdadm
sudo mdadm --assemble --scan
This will attempt to locate any existing RAIDs Then added
/dev/md0 /home/n2o/data ext3 defaults 0 2 /dev/sdc1 /home/n2o/data/tera ext3 defaults 0 2
to /etc/fstab (adding in the 1TB hard drive while I am at it)
In 10.04 I created a new RAID5 array. In order to get it to mount after a reboot (and adding it to fstab) I had to do the following
sudo mdadm --examine --scan --config=mdadm.conf >> mdadm.conf
Ubuntu 16.04 after rebuild
Just did
sudo apt-get install mdadm sudo mdadm --assemble --scan
Then added
/dev/md0 /media/raid ext4 defaults 0 2 /dev/sdf1 /media/nonraid ext4 defaults 0 2 /media/nonraid/Video /media/raid/media/Video/video-ext none bind 0 0
to /etc/fstab
Samba
Hardy is a bit different to previous versions for sharing folders.
sudo apt-get install samba smbfs
Don't really need smbfs, but what the heck).
Create the users for the system, add them to user group user (not necessary, but could make things easier in the future). Use the following user IDs for each user to pick up the previous permissions
- 1001 chris
- 1002 mina
- 1003 bener
- 1004 mark
- 1005 almina
Add these users to samba
sudo smbpasswd -a chris
for each user.
In 10.04 I also had to add the following in /etc/samba/smb.conf
follow symlinks = yes wide links = yes unix extensions = no
16.04 Upgrade
sudo apt-get install samba
Create users in normal Ubuntu control panel.
Add these users to samba
sudo smbpasswd -a chris
for each user.
Must log on to each user to construct default folders in ~ directory. Create folders in ~ to map raid/nonraid folders to, eg ~media, ~/personal, ~/family, ~/software, ~/tmp etc
The follow symlinks etc no longer works, so must map folders in fstab:
sudo gedit /etc/samba/smb.conf
[homes] comment = Home Directories browseable = no read only = no
sudo /etc/init.d/samba restart
Edit fstab thus:
sudo gedit /etc/fstab
Add it for each user/folder share:
/media/raid/media /home/xxx/media none bind 0 0 /media/nonraid/Video /home/xxx/media/Video/video-ext none bind 0 0 /media/raid/personal/xxx /home/xxx/personal none bind 0 0 /media/raid/family /home/xxx/family none bind 0 0 /media/raid/software /home/xxx/software none bind 0 0 /media/raid/tmp /home/xxx/tmp none bind 0 0
Tuning
- Adjust swap file settings
