BIG PROBLEM - Reshaping mdadm RAID5
I have a huge problem. A couple of days ago I've runned a reshaping of my RAID5 array from 10 to 8 HDDs. FS is ext4. So first I've done:
resize2fs /dev/md2 11000G e2fsck -f /dev/md2 mdadm /dev/md2 --grow --array-size=12000000000 mdadm /dev/md2 --grow --raid-devices=8 --backup-file=/root/backup
But then I've done some stupid thing. Didn't calculate the size and executed:
mdadm /dev/md2 --grow --raid-devices=7 --backup-file=/root/backup
I've stopped the reshaping process at about 10% (it took some tim for my stupid brain to process what I've done)
Will I be able to fix the file system after that reshaping ? Or I've lost 10TB of data ??
Any suggestions welcome (preferably ones that will help me to keep my data)
