OMV 3 only default settings I have 10discs in a raid 6 array or i had... Now when i boot up i get an error saying .not enough discs to build array. 4/10

Zitat von ryecoaaron

cat /proc/mdstat

i did that but, then i got this
how can i see on what drive the superblock is?

thanx for the support ryecoaaron btw , i really like it , , i have no usb key or omv attached to the machine just drives and usb dvd-rw

I have moved out the drives and stacked them ontop of eachother so i can handle the cables more easily :)..

seems like i swapped the discs / cables around maybe...the drives show up atleast....
i have more pictures also with command output

Ok , just to be sure .
To rebuild the array, do i need to have the omv boot media attached ? I cloned the messed up USB you know.
I assume resquecd is enough to rebuild.??
Maybe more moderators could help ?
This is abit , is the arrayinfo stored on all the 10 driver Or only on the omv installation

Thanx for your reply , so there something more i could try ?
By the way , Did not meen to upset you.
I know you are elite at this ,)
Just abit Sad about the whole thing ....

Ok i understand . Just got Therese discs and new chassi and stuff so not fun.
But the good news Is the data mostly torrents that i can download again. But alot of Them..

IF i could find where the superblock is Then maybe
IT reports that IT cant be found on sda
When i do this.

Assuming sdk is still the boot drive, I would try:

mdadm --stop /dev/md0
mdadm --assemble --force --verbose /dev/md127 /dev/sd[abcdefghij]

Hi again ryecoaaron , i was actually able to create a md0 with a command i googled.
got 9 out of 10 drives , and added the last drive in the webgui , so the raid is up again
and now new data has been written to the discs since crash..

one problem tho no files or filesystem popup in omvwebgui
the raid shows tho

is there away ti get the actual files back? or filesystem and folders?
using command or som resquecd

my array is called md0 now

not new data
no new data should it be....:)

i did a fresh install on omv an a external harddrive.

and the raid6 filesystem are there during install , but as i said no filesystem , i think there is a way to fix that , or hope

fsck.ext4 /dev/md0 did not resolve in any filesystem tho get errors

Oki , i learned something atleast.
I workt out what exakt drives that had bad superblocks.
I also found out how to display copies of superblocks on each disks.
Tries to fix/repair Them .
But Did not got any luck , but Its abit like investigating
I think that omv Did not like that i had feernas installed on the disks .
Because 2 reported as zfs members and i Did not enable that in omv.

the last command i was hoping to fix part of the problem , but i think it fuxurd the filesystem

The last command on the screen in that picture , i Should say

Question : is there away to get what you had in the recyclebin on omv.
I empty IT by mistake .
