RAID5 with all disks (5x2TB)

[Basajaun]

Hi team,

is possible install firmware and create RAID5 with all disks (5x2TB) ? Now i have (1x2TB + 4x2TB(RAID5)).

Thanks in advance !

Best regards,

[Jocko]

Yes you can

But you need to make it with several steps.

First backup your data stored in sda :
- select your raid volume as new addons volume. By running it, you will move all your technical shares (if you select the related option) to the raid volume (fvdw, mldondkey, .... shares)
- move manually the other shares, created on Vol-A
- grow your raid by adding Vol-A in the current raid (use the volume menu : click on the volume name link of your raid volume in the main disks setup menu)
- resize the fs of your raid (use the volume menu : click on the volume name link of the main disks setup menu)

Note: growing and resizing will take a long time.

Hi Jocko,

i've followed your instructions and i get this error message:

Fail: could not grow the raid volume! : (120)

Thanks a lot !

Best regards,

[Jocko]

error 120 means the firmware failed to add your disk as a spare disk in the raid before growing it.
maybe because it failed to unmount sda8 at the previous step :scratch
Please to post

Code: Select all

ls -l /direct-usb
mount
cat /proc/mdstat

Jocko,

is my mistake, perhaps my root connection was on VAULT volumen, now i execute cd / command. After this i've executed RAID5 grow and now is executing tasks.

Thanks.

Sorry !

As now sda8 is really unmounted, I expect you will succeed this time.

So try to repeat

(Anyhow this allows me to find a bad coding :dry )

---edit---

No this can not prevent the firmware from unmounting sda8. But yes if the current directory would have been on the vol-A

Jocko,

big5vs1 is working on expand raid5.

Thanks !

On this menu, you will get a message and an additional button for resizing the fs when raid reshaping is complete

Thanks Jocko !
