kdyz pouziju -f (force) tak to stejne nejde ... ruzne jsem menil poradi --manage a -f apod, ale vysledek porad stejnej:

Kód: [Vybrat]

# mdadm -f --manage /dev/md0 --fail /dev/sdd1 --remove /dev/sdd1
mdadm: cannot find /dev/sdd1: No such file or directory
mozna podstatna pripominka je, ze to delame na zivem serveru s hotpluggable scsi diskama

^^ tady je patrne, ze jsem *hotplugnul sdf, udelal (to uz neni patrne) ``dd if=/dev/sdc of=/dev/sdf bs=512 count=1'' abych zkopiroval partition table a udel `partprobe' a normalne ten disk pridal do raidu .. jeste me zarazi hlaska:

ale to asi nicemu nevadi ...

summary: jak odebrat zaziva ty *zheble disky, pripadne zodpovedet co se stane po rebootu ? zustane /dev/sdf a nebo se naindexuje jako /dev/sdd ?

zdravim, ntz
