Help Resizing MPath Partition

[deejay33]

Hello All,

I am working on expanding a partition on my SUSE Linux Server but having a problem doing so. Here is some background on the setup.

- The drive is a "Virtual Drive" on a Dell San device
- I have increased the allocated space to that virtual disk from about 973GB to 1.16TB
- I rebooted to make sure the system rescanned the drives
- I can see through "Partitioner" that 1. the /dev/sdc drive now shows 1.1TB as it should and 2. the /dev/mapper/mpathc partition is listed at 1.1TB as well.
- Looking at "partitioner" it lists that partition type as a DM.
- The underlying file system for that partition is ext3 and I am not using LVM on that partition.

The issue is using the df -h command, I still only see 973G.

I attempted using the multipathd -k"resize map mpathc" command but it sat for over an hour and I never saw a change.

I'd appreciate anyone's help on how to expand what the file system sees.

Attached is a screen shot of the df -h, fdisk -l and Partitioner window.

Best regards,

Hello Chgwhat,

Thank you for your reply. I think were on the right track. The fdisk -l does show /dev/sdc as 1245 GB as is it should with the new space. I am confused though at the partition nameing and what to resize. In the example, there are sda1, sda2,etc which I understand are partitions on sda.... on my system, I the disk is sdc, but I have no sdc1 for a partition. What I do see is /dev/dm-3 which matches the sdc size. Would that be the partition on my system? So is it already expanded meaning I just need to resize the file system?

Looks like you just need to resize the filesystem as you have no partition.
