I have a Ubuntu PC using Ubuntu 19.10. In 2011 I had a serious car accident and one of the by products of said accident is an extreme difficulty holding things in my memory. Long term things are fine, as are things that I read, but I tend to forget, for example what I did last week.
My background before the accident was in IT (I was an MCSE) and I already had a Linux box setup as a media server for home using Mythtv.
After the accident I could no longer work, so I amused myself by changing distributions from Fedora to Ubuntu, adding hard drives to my Ubuntu system and various O/S upgrades etc over the years.
This brings me to my problem, I now have a large number of hard drives attached to my Mythtv system, but when I compare the amount of storage space that I have, to that which I am using, it's less that 1/2.
I need some kind person to look at my list of available drives, formats and files and suggest a way to rationalise things for best performance with some redundancy (I have no redundancy at present and I would be broken hearted if I lost everything) I do have the spare capacity to create some sort of raid.
These are the Available drives: Disk /dev/sda: 4001GB Disk /dev/sdb: 4001GB Disk /dev/sdc: 4001GB Disk /dev/sdd: 6001GB Disk /dev/sde: 4001GB Disk /dev/sdf: 128GB (ssd) Disk /dev/sdg: 2000GB Disk /dev/sdh: 4001GB
Total drives including a 256GB Solid state (not currently switched on) 128gb+256gb+2000gb+4001gb+4001gb+4001gb+4001gb+4001gb+6001gb = 28390GB or 28.39 TB
Of this space I am using a Storage LVM which is 13889gb in size and a boot drive / swap.
The PC has 8gb ram installed.
