Topic: How resize raid...

[Mac]

Drive /dev/hdc failed
replace a new one
but,

Disk /dev/hda: 255 heads, 63 sectors, 3722 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1   *         1        33    265041   fd  Linux raid autodetect
/dev/hda2            34      3722  29631892+   5  Extended

Disk /dev/hdc: 255 heads, 63 sectors, 3654 cylinders

/dev/hdc6            36      3654  29069586   fd  Linux raid autodetect

disk /dev/hdc are smaller a little bit and md1 dont recovery


  Personalities : [raid1]
read_ahead 1024 sectors
md2 : active raid1 hdc1[1] hda1[0] 264960 blocks [2/2] [UU]
md0 : active raid1 hdc5[1] hda5[0] 10432 blocks [2/2] [UU]
md1 : active raid1 hda6[0] 29345280 blocks [2/1] [U_]

How can I resize /dev/hda6 ???
