quick help needed - smaller disk in raid5?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello everybody,

I've been using a Raid5 with 3 disks of exactly the same size, a little bit 
more than 250 GB (reported as 251)

Disk /dev/sdc: 251.0 GB, 251000193024 bytes
255 heads, 63 sectors/track, 30515 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1       30513   245095641   fd  Linux raid autodetect

Now I want to add a 4th disk - and got one slightly smaller:

sanjose:~ # fdisk -l /dev/sdd
Disk /dev/sdd: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdd doesn't contain a valid partition table



Is it nevertheless possible (with some minimal losses in possible size) to add 
the new disk? The Funny thing - all disks are from Maxtor, and should have 
the same size.

Thanks a lot

Michael
