I have Dell PowerEdge R730xd running Centos 6. I just added more physical disks to our raid and used open manage to increase the raid size, which is now at 67,063.50GB. I'm using xfs and have a lv (lv_vol1a) that I would like to extend using xfs_growfs to use all of this free space. I do not want to reboot the system.

I can see the space on openmanage but I do not see in vgdisplay:

[root@crich ~]# vgdisplay

Here is my lvdisplay:

Here is my parted info:

What do i need to do to have xfs_growfs be able to access the free space?


I was on with Dell support today. They created a new partition with parted but it still is not recognized by pvcreate. I have to reboot the server which is not something I wanted to do. Any way here is lsblk:

  • You need to change your partition-table, then resize your physical volume. However, I'm afraid that if your RAID grew from 300 GB to 67 TB, you cannot do this with your msdos partition table, but need a gpt table. This will not be easy and it won't work without a reboot. – Andreas Rogge Mar 12 '18 at 19:19
  • My RAID is currently 37T, if you look at the lvdisplay output it says /dev/vg_vol1/lv_vol1a is LV Size 36.38 TiB. I'm seeing anything like that in parted though. – user460272 Mar 12 '18 at 19:26
  • can you please provide the output of lsblk? – Andreas Rogge Mar 12 '18 at 20:36
  • You can try running partprobe. But if the partition doesn't show up still, then you will need to reboot the server to continue. – Michael Hampton Mar 13 '18 at 20:19
  • Sadly I had to reboot. I'm not sure if there is any way to create a partition under these circumstances and not reboot. – user460272 Mar 15 '18 at 15:44
