Hey has anyone run into issues with trying to grow a Linux software raid? I’ve
just finished syncing all of my data from 3x2TB (in raid 5) to 3x3TB (still
raid 5). The raid array should show a capacity of approx. 5.5 TB, but instead
shows only 4. I’ve tried re running the mdadm –grow command
Hi Andrew, are you using the raid for boot and root?

Did you resize the file system? I have two 5.5 TB arrays (one 4 disk RAID
5 and one 5 disk RAID 6) both built via mdadm. One of the arrays has been
resized 4 times over the years.
What distro and kernel are you running? I seem to remember there being a
kernel parameter for large block devices (
I forgot to ask some other relevant questions:
Are you using LVM on this array? How are you not seeing the increase in
space (are you using df or mdadm --detail to get this information)?

I am using LVM onto of this array. As for the other part of your question here
is the output from mdadm --detail. I have 1 disk removed at the moment because
I'm trying to reformat it with parted instead of fdisk to see if it makes a
difference

Hi Andrew, could you post the output from the following please?

The previous command should be:
cat /sys/block/md127/md/component_size
in order to match the device in question. You previously used "mdadm
--details /dev/md127".
The following site describes a similar problem to the one you are having.
