A search for "<your distro> RAID" should lead you to some useful documents.
There is one I can't quickly find that discusses rearranging RAID partitions, changing RAID levels and so on.
That would give you a starting point.

So far I have found tools to recover Linux.
I am after restoring specific , already data containing RAID5 array.
Looks as I could used mdadm --assemble
I cannot find anything stating it will keep exciting data intact.

You can use --fake or -f to get mount to test your fstab.
What you put in /etc/fstab depends on what your raid is like. If you're using a hardware raid controller, then the RAID cluster is probably presented to the OS as /dev/sdx, but if you're using software raid, the I think the cluster is presented as /dev/mdn.
After creating your RAID, you'll need to partition and format, just like a normal Hard drive. Once you've done that, you can use blkid to get the UUID of the partition for fstab.

You've got several options. Lets assume that you wan to mount the ext4 partition on /data
You can use the physical partition device path, the UUID, LABEL, PARTLABEL or PARTUUID in fstab
The following are all equivalent. Use only ONE.
# by device path:
/dev/md42p1 /data ext4 defaults 1 2
# by UUID:
UUID=b4f937f3-8d8d-4d1b-a9e6-4eaffb72a077 /data ext4 defaults 1 2
# by LABEL
LABEL=MD42_RAID_LABEL /data ext4 defaults 1 2
# by PARTLABEL
PARTLABEL=MD42_RAID_NAME /data ext4 defaults 1 2
# by PARTUUID
PARTUUID=49fce049-084f-48e8-aa79-f6e22d809879 /data ext4 defaults 1 2
depending on your requirements, you may want to change the defaults, to add perhaps noatime, for example.
Note that we mount the partition not the RAID drive.
Keep Calm and Carry On

so, i was doing some programming with eclipse and stuff. But then i noticed that all of my .JAR files suddenly looked like a pinguin with some painting stuff on his hands. i need help, cause im not sure what is going on!! I use windows.
[SOLVED] I had to right click a JAR file, and "press open in application" then select Java JDK. For some reason i had two of those...

O M G.
For someone who doesn't want spam, you sure made it really easy for spammers to pick up your email address by posting it in public forums.
YES, they have crawlers that will scan public forums (like these) for an email addresses.
So, if you want to minimize the spam you get, NEVER post your email address in a public forum.
So you don't want spam, but yet you spammed the forums here yourself?!?! Go back and delete your other posts, except for the one in the Java forum.

So, you are smart enough to guess that the ".JAR files" look something like a Linux, but you want people to connect with you on email threads; won't work man.

We already have Crystal Reports built for Asp.net. We are studying the possibility to move the Crystal Reports coded in Asp.net to LInux through Mono, does anyone has experience of this?

.NET Framework on Linux works through Mono; even the updated .NET Core uses a lot of components and structures from the Mono project.

It should build just fine as long as you have Mono SDK setup. There might be some minor changes (such as file system, permissions, etc.) other elements would be okay.

Facts:
0) I'm writing a .Net Core 3.1 command line app (using C#) to read text files on some Raspberry Pi machines on the network. This app will be able to run on either Windows or Linux.
1) The files in question are in the /etc, /proc and /sys folders.
2) I don't want to create shares of these folders.
3) I'd prefer not to have to install/configure anything on the remote boxes (if at all possible).
4) I know the user ids and passwords for the remote boxes, and am aware that I have to somehow use these credentials in order to "connect" to the remote boxes).
5) I don't want to use another language. I mean, doNet Core is supposed to be cross-platform, right?
Problem:
How do I go about reading a file on a remote linux box? I've tried a number of ways to do this, but I keep getting the following exception:
"The network name cannot be found. : '\\\\192.168.1.10\\sys\\class\\thermal\\thermal_zone0\\temp'"
(BTW, when running in Windows, the exception is presented with backslashes. I'm actually using forward slashes.)

It supports .NET Standard 1.3 and 2.0, so it should just work in Core.

I added SshNet with Nuget, and it workds great. 
using SshNet;
using (var client = new SshClient("192.168.1.10", "userid", "password"))
{
client.Connect();
string data = string.Empty;
using (SshCommand cmd = client.CreateCommand("cat /proc/cpuinfo"))
{
data = cmd.Execute();
}
}

FTP?

FTP would require both installation and configuration on the Linux machines. SSH service is installed by default but not enabled.

Is not FTP installed by default on all Linux machines nowadays?
I honestly would have taken that for granted. FTP was developed in the days when you measured program size in kilobytes. The protocol is so simple that a student could implement it as homework assignment #3. I can't see any reason for taking it out.

No, not anymore. There are better replacements such as SFTP or SCP. Curl or wget can be used as FTP clients if absolutely necessary.

Those days nobody could imagine the need for network security. FTP transmits everything, including user credentials, in cleartext. The protocol design makes it difficult to pass through firewalls without causing additional security risks. In general, it's just too dangerous and should not be used.

Do you want to force linux to do the windows thing, or windows to do the linux thing?
For the former run samba on the linux box and create shares you can access from windows. This will probably suck, the degree to which it sucks will depend on the file system you are using on the linux side.
For the latter you can run an ftp server on the linux side or setup ssh and use scp. These will suck less.

I found a solution - use the SshNet library and I don't have to do anything on the other pi's on the network.
