You can only grow a RAID5 array in Linux as of 2.6.20 AFAIK. Justin. On Thu, 1 Mar 2007, Laurent CARON wrote:
Hi, As our storage needs are growing i'm in the process of growing a 6TB array to 9TB by changing the disks one by one (500GB to 750GB). I'll have to partition the new drives with bigger partitions and then fail the array, remove a drive, add a new 750GB disk.... repeat it as long as 500GB disks are remaining in the system. The question now is to know if i'm right, or ... simply wrong in thinking that this operation is then just as simple as: server:~# mdadm -G /dev/mdX -n number_of_disks(same as original array) once done, i'll have to grow the filesystem (ext3) by issuing server:~# resize2fs -p /dev/mdX Does the fact that the ext3 partition is nearly full involves a bigger risk of screwing the data ? Would it be better/worse to have a bitmap (internal one) on the mdX device while growing it ?
