OMV 6 with ext4 and raid5

Zitat von spongebob

I dont want to lose any data and omv configs (raid5 and ext4)

Regardless of the drive format and drive aggregation method used, if you don't want to lose data, you need -> backup.

It should be much simpler (shutdown, remove drive, put new drive, turn on) like in Qnap or Synology

You get what you pay for. Qnap and synology have hundreds of people who work on and develop their NASes. They also have complete control of their hardware. OMV runs on everything from an RPi to huge servers. Much harder to make everything super simple. If you need simple, you will have to purchase commercial hardware or contribute to the project.

Hardware raid!! on server grade hardware that is capable of running windows server that has a GUI for the hardware raid controller

I'm not arguing with you but,, man,, buying those turn key boxes results in a number of undesirable things:

1. Low spec hardware (without ECC ram) that, generally speaking, supports only old tech RAID.
(With no mention or attention to backup, which is a computing sin when running RAID.)
2. Really sparse support that, in most cases, lasts only until the end of the warranty. (Generally speaking, 1 year.)
3. Little to no hardware expandability, beyond what's provided in the propriety device.
4. Server software add-on's are much more limited, and potentially expensive, when compared to open source counterparts.

3. Extreme expense for what the buyer actually gets, when all of the above is considered.

This comes from experience with an HP EX470 home server. All that could be done to it was a "memory upgrade". Anything beyond that required actual modification, hacking it for access to BIOS, etc. Not too long after I bought it, Microsoft abandoned the OS - MS Home Server. (From there, there was no path to loading another OS without, again, hacking the device.) Even during the supported period, ALL server add-on's were 3rd party that had unreasonable prices for home use, for the function they served.

Something you might consider:
In this one thread, you've received more responses than you're likely to get from tech support at Qnap or Synology. So, if you decide to go the commercial route, hopefully you won't have a problem that is not covered in their documentation and / or is outside of the warranty period.

I have owned or maintained multiple QNAPs. They all ran OMV though. Just saying that OMV is free and there are effectively two people working on it in their free time. So, OMV is not going to have everything the paid device has with hundreds of people working on it.
