Zkousel jsem obnovit puvodni pole pomoci

mdadm -Cv /dev/md0 -l5 -n6 /dev/hde1 /dev/hdc1 /dev/hda1 /dev/hdk1 /dev/hdi1 /dev/hdg1 --assume-clean

a pak i pomoci:

mdadm -Cv /dev/md0 -l5 -n5 /dev/hde1 /dev/hdc1 /dev/hda1 /dev/hdk1 /dev/hdi1 --assume-clean Avsak mount hlasi: mount: /dev/md0: superblok nelze přečíst, takze ocekavam ze timto zpusobem se na data nedostanu. S daty nebylo dale nijak manipulovano a ani neprobehl dalsi sync, pripadne reshape.

Mam sanci data nejak zachranit. Diky moc za podnety.
