comment What does exit 99 means?
Not quite - 99 is not zero, and so indicates that the program failed for some reason.

comment I can see my LVM but I can't initialize it. Missing UUID of one of the disks
@Dalif, those device names are not stable and can change over a reboot, even if you don't add or remove any drives. Just because you gained an sdd when you added the new disk does not mean that drive is the new disk. Why would you think removing the new disk would change anything? You have unknown device because one of the old disks has been formatted and is no longer recognized.

comment System Halt on REBOOT, Shutdown & Restarts as expected
Ahh, in that case, the kernel may be leaving the device in a state it does not reset properly from.

That's kind of the whole point of suspend...

The message indicates that either the card or slot it is in are broken. I don't see how what kernel you use could affect this.

comment Why is writing SLOW on raw device, and FAST on filesystem (USB key)?
@Bananguin, your argument is equivalent to getting in a car accident on the way to work, and claiming that working causes car accidents. It may be true that had you not gotten in the car at that time to go to work, you would not have been in that particular accident, but you can not conclude that working causes car accidents. It just so happens that is where you were going when you got in one. Here, it just so happens that the filesystem put the data in part of the disk that is faster than where the OP dd'd to. That doesn't mean that the filesystem magically is faster than dd in general.

comment File has bytes - appears to be empty
Then there you go; it crashed and rebooted before the data hit the disk, so it was lost.

comment How to get CPU Percentage as a Counter?
@KyleBrandt, either you want the percentage of utilization, in which case, you have to divide by uptime, or you want a count of non idle time, which is not a percentage.

comment How to get CPU Percentage as a Counter?
@KyleBrandt, no, it does not "work out", which is why you are getting all sorts of goofy numbers. You have to have a divide by uptime in there, like goldilocks's answer shows.

comment How to get CPU Percentage as a Counter?
@KyleBrandt, no, measuring something in centisecs does not make it a percentage. Calculating the ratio of that measurement to a theoretical maximum does.

comment Why is writing SLOW on raw device, and FAST on filesystem (USB key)?
@Bananguin, no, it gets better when you write to a different part of the disk. The fact that the filesystem happened to cause that is incidental. Depending on what filesystem you used what else is on the disk, it very well may have decided to put the file in the "slow" part of the disk instead.
