Re-doing my drives setup, what's my best approach?

Hi,

I'm going to be upgrading my OMV HDDs setup and I'm looking for suggestions on the best way to go about it.

What I have:

HDD1 (old) has my data on it and it is mounted under /srv as a NAS drive.
HDD2 (also an old one) is mounted under /media and is my backup drive.

What I want to do:
I have two brand new WD Red Plus drives (call them HDD3 and HDD4) and I'm thinking I want to set them up as a RAID 0 array, and keep HDD2 as backup.

So, how do I get there from here? I could set up HDD3 as a second NAS drive and let OMV sync the data to it from HDD1 to it, then maybe pull HDD1, plug in HDD4 and tell OMV to make HDD3 and HDD4 a RAID 0 array (and that HDD3 is the "source" drive somehow, IOW, the empty HDD4 is not the data source to sync from. Not sure how that works.

Does this make sense? There may be a how-to that covers all that.

Thank you!

Of course! Saturation is good, no? The pancakes were saturated with syrup?

Okay, no Raid 0. I'm ashamed I even mentioned it. Silly me.

So -- a NAS drive and a backup drive. More better?

First Step: I need to migrate my data from the present 2.5" NAS HDD to one of my new WD Red HDDs to make that my new NAS drive.

Then the 2.5" drive becomes redundant and I pull it out of NAS service.

What might be the best way of going about this?

Excellent questions, I should have put this basic info into my OP.

1. Raspberry Pi.
2. The existing NAS disk is a old 2TB 2.5" WD "My Passport" portable that has traveled in my luggage for years, while the target NAS disk is a new 2TB 3.5" WD Red Plus.
3. The reason that I initially set up OMV with this old HDD is because I wanted to check out OMV and see if I like it. I do!

I keep a nightly backup of the NAS HDD (sdb1 mounted under /srv) onto a second HDD (sda1 mounted under /media). So all my data are on hand, so I suppose I could just disconnect the existing NAS HDD and plug in the new, then cp all the data from the backup drive to the new NAS drive. But there may be a better way.

Side information of no particular use: We have a Synology NAS in our home in Oregon. We just bought a house in Mexico to winter in. That's where we are now, and I want to set up a less-expensive NAS here and OMV+RPi seems to be a nifty solution. I just want newer HDDs.

Thank you for your help!

Cool. What I'm not finding in the webgui is a graceful way to disconnect/unmount/forget the existing NAS drive. A pointer would be appreciated.

And many thanks for the help.

Well, under Storage > File Systems and highlight the NAS drive I see "Create | Mount," "Edit," "Resize," "Quota," and a gray-out square that has no tool-tip. I'm guessing that's the unmount button, mimicing the "stop" button in a music player.

This Windows 10 machine has a drive mapped to that NAS HDD, so I'll start by unmapping it and removing any other entries here that point to it.

Thank you! This is a fun little project.

Hi, Chente

Right now I am in the process of copying the content of my mounted but temporary NAS HDD to my also-mounted target permanent HDD. A lot of data and rsynch is chugging along.

I have one question: Is it accurate that in order to unmount a NAS drive, one must first shut down the associated services, like FTP, samba and such before the unmount button becomes available? I think that's exactly what you said but I want to double-check. Thank you!

Zitat von chente

If you want to avoid creating them again, you can edit the services and point to a folder on another disk, or an empty folder.

Under Storage > Shared Folders I see my shares on the old HDD that I would like to point to folders on my new HDD. I expect that it's the UUID that needs to be changed, but the Edit tool doesn't seem to allow that. Is there another way that I am not seeing? My wife correctly says that I suffer from Male Pattern Blindness.

LOL, true!

No not many shared folders. On the old NAS HDD (the test HDD) I have two shared folders, on the new NAS HDD I also have only two shared folders. I cannot turn on the square "unshare" button for the two shares on the old drive. I disabled SSH, SMB, and FTP services and still the button is grayed out. So I'm kind of stumped. I might just unplug it!

GOT IT! Sweet. Yay! OMV is a nice bit of kit. Thank you for all the help!
