Very thks !

Hi,

I have the same problem with OMV web

rpc-password: The value 'openmediavault' doesn't match the pattern '/^[^'"\\]+$/'.

Thanks

Hi all,

I have a problem with OpenVPN.
When I start OpneVPN with just the server, I can me connect to VPN.
When I start a client (file download in a site) and the server, i can't connect.

I have this errors :

P_CONTROL_HARD_RESET_CLIENT_V2 and P_CONTROL_HARD_RESET_SERVER_V2

Do you help me ?

Thank you

Fixed in 3.10 in repo now - https://github.com/OpenMediaVa…9d7f8d2e238c521477aa5f5e8

Yes I saw

Thanks

The first question you should ask yourself is why you want to play RAID. Most probably the answer has something to do with data protection and then you're already wrong (RAID is not backup).

RAID-1 only protects from a hard drive fail (happens not that often) and doesn't provide any more benefits. It's all about increased availability and reliability.

If you are concerned about availability and reliability why do you choose then the most crappy platform possible? Every Raspberry Pis from a NAS point of view is just horribly unreliable and way too slow anyway.

• Those things suffer from underpowering problems
• The CPU has only one single USB2 connection to the outside
• If you want to access USB storage you want to use UAS (USB Attached SCSI). Cheap SBC like an Orange Pi Zero for $7 can do UAS but Raspberries not (they're only capable of the old and slow BOT mode)
• Every disks connected to a Pi is behind the same internal USB hub
• Even the Ethernet interface is behind the internal USB hub
• On RPi 3 B+ it's not just one internal USB hub but two cascaded ones (they managed to make things even worse)
• All devices behind these internal USB hubs have not only to share bandwidth but add to USB bus contention problems
• The internal USB hub is a so called SPoF (single point of failure -- RAID is all and only about eliminating those!!!)

Adding to this: to access USB disks flawlessly you need a perfectly working USB-to-SATA bridge inside the drive enclosure (99% of USB disks connected to a Pi do not apply). RAID rebuild times are horrible since bottlenecked by the single USB2 connection and shared bus. The time a rebuild takes your array has no redundancy any more. Such a RAID rebuild is disk and bus stress. What if now the most prominent SPoF on these thingies fails? When the internal USB hub decides to fail with heavy RAID accesses your whole array is gone instantly.

RAID with USB disks is already insane given the many problems that prevent reliable operation. USB RAID with all disks behind one USB2 hub is close to stupid. Do yourself a favour and don't try this. It's a useless waste of at least one disk and the setup will fail when needed anyway (RAID rebuild after a disk failure, maybe even before. Just search the forum or see here directly).

Thanks you very much for your explain. You have open my eyes for RAID via RPi. For me, RPI is not expensive. And the RAID it's just perfect for me for data protection (in addition to a backup).

OMV it's just perfect for a home NAS. I use this

I recommend not using raid with usb and highly recommend not using raid on a RPi.

Why? I found different how to for create RAID with RPi ?
And with that create RAID?

Hi,

I have a problem with last build OMV_3_0_99_RaspberryPi_2_3_4.9.80.img
I have a Raspberry 3 B+ and Raspberry 3 B with the same problem for both of them

I did a fresh install into a USB Card and installed it.
After, I have 3.0.79 version of OMV and kernel 4.9.80-v7. In the RAID menu, I found my two disks (/dev/sda and /dev/sdb).

Then I waited for the update and reboot.
After, I have 3.0.99 version of OMV and kernel 4.14.30-v7. And in the RAID menu, I don't find my two disks. It's empty !
I can't create a RAID 1 with my two disks.

Do you have a solution to resolve my problem?

Thanks
