comment Bad Archive when installing Ubuntu over PXE - it's looking for the Release file I do not host
If you are hosting the dvd then you should have the Release file ( it's there in the dvd ). You must have done something simple like point it to the wrong directory.

comment Free space at home partition is not as expected
The filesystem keeps track of used/free space. The only thing special about an ssd is that it internally moves data around where it sees fit ( and pretends it is still where the fs put it ) and it can do so more efficiently if the filesystem gives it a hint as to what parts of the disk it doesn't care about ( it considers free ) so the ssd doesn't have to preserve those when it rearranges itself internally. In other words, it is just a performance optimization.

comment How to find swap usage per process when conventional methods fail? (15.04)
Check df and see if any of your tmpfs filesystems are loaded up with lots of files.

comment Free space at home partition is not as expected
I dunno then... did you run a fsck somewhere in there? The only other thing I can say is that fstrim works by first creating a file to occupy all of the available free space and then issues discard/trim on that, so if you didn't have free space already, it couldn't do anything. Also you said you ran fstrim on your root partition, not /home. For that matter, df said your entire /home partition was only 1.4 gb in total, which is rather small.

comment Installing ubuntu on VM Ware Windows which has SATA + SSD hard disk. (Which is a Hybrid Hard Disk)
"If the host system is nothing".. that doesn't make any sense at all. I feel like you don't understand what a vm is. To the guest, it just thinks it is running on a pc with whatever hardware your vm is configured to emulate. It has no knowledge of the host OS or the real hardware.

comment Free space at home partition is not as expected
No, that is not correct. trim just tells the SSD that the blocks are free so it can better manage the blocks that are actually used. It has nothing to do with what the filesystem considers free or used. Most likely you just had a program running that still had a large file open that you had deleted. It isn't actually removed until it is closed, which rebooting took care of.

Just restore from backup... you do have a backup right? If not, it's a hard lesson to learn.

@SharadGautam, the type of computer you are running on ( in this case, a virtual one ) makes no difference.

comment Administering three disks in RAID 5
No... create is for creating a new set.. an existing set is --assemble'd, though this happens automatically and you just go mount the thing. It warned you that you were trying to create an array out of disks that already appeared to be part of an array and you pressed on, so you destroyed your data.

comment Administering three disks in RAID 5
You don't have any data on the disks. So far all you have done is take some empty disks and combine them into a raid array.

Of course you can't mount it, you didn't format it!

comment The CRC for the main partition and back up partition table are invalid
More detailed errors about the "IO error" can be found after by running dmesg, but most likely, your drive is failing.

comment Phantom Partition … how do I correct this?
Yep.. there really can't be anything in that partition that could identify it as an iso9660 fs.. something has really gone wrong with udisks. File a bug against the udisks2 package and include the output of udisksctl dump.

comment Phantom Partition … how do I correct this?
Not in linux... it always exposes an extended partition as having only two sectors, regardless of how many lie between the EBR and the logical partition ( though that almost always is only 2 ). The fact that it is exposed this way, and indeed at all, is a hack that dates back to LILO: exposing the first two sectors allowed LILO to be installed there and chain loaded by DOS MBR boot code.
