Personalities : [raid0] [raid1]
md4 : active raid0 sdd4[1] sdc4[0]
102399872 blocks 64k chunks
mybox hedmo # fdisk -l /dev/sdd /dev/sdc
Disk /dev/sdd: 74.4 GB, 74354687488 bytes
60 heads, 21 sectors/track, 115257 cylinders, total 145223999 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x544f4f42
Device Boot Start End Blocks Id System
/dev/sdd4 2048 102402047 51200000 fd Linux raid autodetect

hedmo,
What doesshow ?
In particular, near the bottom | Code: | | Free PE / Size 367844 / 1.40 TiB |
shows I have 1.4 TiB in the volume group, not yet allocated to any logical volumes.
The following assumes you have some free space too.
You needread the man page to change the size of your logical volume for /home. This is akin to making the /home partition bigger.
Warning be sure you understand the difference between -L 10G and -L +10G
After that you need to resize the filesystem. The command for that is filesystem type dependent.
For extX its resize2fs - read the man page for the detail.
With extX it all happens on the live mounted filesystem.
Warning ... some filesystems do not support resizing, some only support growing, others support growing and shrinking.
If you don't have any unallocated space, you either need to grow your Physical Volume first, or shrink other filesystems to omake free space.
Shrinking is harder and again, its filesystem dependent.

hedmo,
Use the partition tool of your choice to make a new partition for the remaining space on each drive.
Raid it if you wish. Donate the new space to a new Physical Volume or grow the existing Physical volume to include it, then proceed as my previous post.

it worked quite good but there is some problems i can not get my fingers on.
1.i named the new raid "md6" but it has renamed it self to "md127" and always do.
2.my download has dropped from 8mb/sec to 8kb/sec and do not know what the problem is.if i start a "root" firefox from my users D.E i have the right download again. |
