My NAS move from FreeNAS Muad Dib to OMV on a new systems.

I did search a bit through the forum and tried some commands. UNfortunately I cannot access SSH so I cant copy them to full extend here.

Tried
cat /proc/mdstat
blkid
fdisk -l | grep "Disk "

mdstat shows all 3 Raided Disks in md0 and active so looks ok.
blkid shows sda, sdb and sde (the md0 ext 4 RAID5) and the two sdc1 and sdd1 - those two are my UFS drives.
sdc1 and sdd1 have exactly the same entries and numbers for LABEL, UUID, TYPE and PARTUUID but apart from that nothing obviously wroong points to my eye....
fdisk though showed something:
on sdb and sdc it says Backup GPT table is corrupt, but the primary seems OK, so that will be used.

Does this point somebody to an obvious issue?
I am a bit lost...

So
/srv/dev-disk-by-label-StorageRaid5 couldn't be found on /dev/md0 Raid

is preventing the system to boot to webGUI and restrict SSH access too? Shouldn't OMV system be unaffected to be able to debug?

Anyway it has me now. I don't know how to progress other than starting from scratch....
I've made my backup so this should be ok, but I'd be interested in what this is before moving on..

HI. RAID Drives are all SATA 6G. Backupdrive is eSATA 6G. Boot drive is USB2IDE disk

I'll try to boot from USB and try to restore the mountpoint... Let's see If I manage that

Thanks so far...

...on the root cli I was able to mount the md0 array.

I used
mkdir /dev/md0 to create the mountpoint /mnt/md0 and then mounted the /dev/md0 to that which worked ok and on cli I can now see my Raid data.

So far so good.

but how would I convince OMV system to do so during booting?
Can't I repair from root cli so I don't need a systemrescue cd or USB stick?

grub countains 4 Entries
OMV4.16
OMV4.16 recovery mode
OMV4.9
OMV4.9. recovery mode´

In the meantime fdisk -l /dev/sdc  yielded:

GPT PMBR size mismatch (size differs by one) will be corrected by w(rite).
The backup GPT is corrupt, but the primary appears OK, so that will be used.

Is this defect MBR the error?
it is otherwise correctly identified as a FreeBSD UFS.
the other disks a,b, d, e and f appear ok.

Basically I was ready to put sdc / sdd into md0 Array, I was able to mount them and back them up.
could I "wipe" sdc ?
I read about wipefs but do not understand it fully. When wiping the MBR how can it then be accessed... pretty rookie here too...
or format sdc?

Soo...

finally i was again a bit frustrated about my non-knowledge of Linux and decided from a time perspective it would be best to clean the system and rebuild.

I am now back on OMV 3 and had extended the Raid, which needed to be done again on CLI as this doesn't work in OMV webgui for whatever reason.

The ubuntu Community was really helpful here.

A problem is that the mdadm after wiping the UFS disks on after the other and the new systems and after rebooting showed /dev/md127 instead of /dev/md0 as before.... obviously a common issue in mdadm.
I wasn't ablt to rectify this yet and it still is md127 but I can access it and the raid 5 is now online after 9h of extension, checks and rebuild with 3.5TB (I was expecting something closer to 4).

A good thing is that all in all the data was so far never lost because of any user Errors, fails or oddities...

Hallo Leute,

ich habe ganz vergessen zu berichten.

Nach oben benanntem Neueinrichten läuft das NAS nun recht einwandfrei.

Ich habe es nur selten and und fahre es nur hoch wenn ich Daten brauche. reicht mir hin.
Gebackuped wird per Hand mit einer externen Platte und Freefilesync aufträgen.

Bisher funktioniert das ganz gut.

leider funktionieren die email-Benachrichtigungen nicht (mehr). Ich bin der Meinung das ich die während der Testphase erfolgreich erhalten habe (über gmx oder web.de), nun klappts aber leider nicht mehr.

Nach einigem Lesen habe ich rausgefunden das GMX und Web.de scheinbar das problem sind.

Ich habe zwar ein googlemail konto möchte aber nicht zu viele Konten warten und aufmachen.

Woran liegt es das Web.de und gmx nicht funktionieren?

Nochwas: Wie zuverlässig funktioniert die RAM auslastung und Erkennung in der Übersicht?
Ich hatte schon mehrfach den Fall das nur 2 statt 4 GB angezeigt werden. 2x 2 GB Riegel sind drin. Die waren gebraucht und ggf ist einer ja defekt, aber ich bin der Meinung das sich das Bios dann beschweren sollte bzw der Rechner nicht startet.

EDIT: Sorry guys, I realized to late I wrote i ngerman Will continue in English later....

Hey guys.

My OMV is running as intended for some years now with rare use oaccasionaly.

Of course I missed to update regularly, so update requests for the underlying linux System now fail.

OMV tells me that the system is basically to old to be updated.

Back then when I build the NAS, I used a left-over 40GB 1.8" IDE Drive as the system drive. This Drive is pretty Old and it was on schedule to be replaced after a couple of years anyway.

To not block the SATA ports of my System, the boot drive is hooked up with a USB-to-IDE Adapter, which works fine and the system boots from it.

Some things now (forgive the rookie questions):

As I plan to replace the bootdrive:

- does it make sense to put a new, clean up-to-date OMV image to it and re-mount my RAID? Is there anything to do before replacing the Boot drive like unmounting the RAID?

- plan to run SSD Sata drive connected to a USB Interface again for booting. I am worried a bit about TRIM and BSM. Would assume OMV covers that for SSD boot drives, but is this true for USB attached SSDs as well?

- Can the update Process somehow be automated so I don't run into not-being-able-to-update issues in the future?

Thanks for some recommendations and tricks

Thanks for the prompt reply.

Will then be shoping for a new Sysdisk. Probably I just by an external SSD Drive with USB IF, which should as before and report.

By backing up the install, you mean not just cloning the old sysdisk, right? I was about to get the old disk out of the system and store it away until the new Sysdisk runs.... Do you recommend to backup (=clone drive) additionally?

Flashmemory Plugin is a good hint thanks! Will install that...

Thanks again...

Hello. I successfully moved the old system to a new System SSD with Clonezilla.

Basically I am still running on old 4.x OMV but the migration to the new disk worked.

I split the 120GB SysDrive into 3 partitions, one hosting the old 4.x system of the old PATA drive.

Another one should be used for the OMV 5 Upgrade.And the third is there just in case I need to backup a system to another partition.

The USB Stick with the OMV5 ISO etched to it is prepared.

Tomorrow I will backup the raid again to my offline Backup Disk.

(I do this with FreeFileSync via a PC that has the FFS configs)

Before installing OMV5 and mounting the Raid, is there a way to export/import the current OMV4 system settings to the new OMV5.x?

Or will it have to be set up newly due to too many differences in the systems?

Hey. Thanks for the hint. Basically, I don't care using all the space for OMV.

I have a backup of the OMV4 Disk both physically and digitally.

Any hints for the preferences/setting moving from 4 to 5?

Thanks
