Reshapeing after 4 Days with 0.0% progress

Reshapeing after 4 Days with 0.0% progress

[iggy]

Hello Guys,

i wanted to grow my raid 5 with 3 3tb devices to 4 of 3tb devices.

1) i add a new device
2) i grow (please ask me not why i do this) with the help of the button in
webmin instead of the cli 


cat /proc/mdstat:....

After 3 Days of 0.0% of reshaping progress i decided to abort this procedure
- because for me it seems like an error!


Now my raid disapears and i'm not able to mount and backup my data, because
of degraded. So i have no backup file during reshaping.

is there any way to mount my md0 to backup a fews of data before i complete
recreate my raid array?

i hofe for answers..
THANKS!

There are multiple threads here about this problem. What you should have 
done is read them before you "aborted".

http://www.spinics.net/lists/raid/msg49846.html is one example of such a 
thread. There you can also see examples of information needed to help you.

Thanks for your reply,..

i tried all of recommendations that i found - but nothing pushed me to a
working solution...

it seems ....the fast solution is recreating... :(

next time i'll do a full backup before manage the array
