xfs_growfs: is not a mounted XFS filesystem

Question

I am trying to increase the logic volume of my partition disk.Partition table got updated and all went well. To resize the file system, I ran the below command as I am on RedHat.

xfs_growfs  /dev/vg_osdisk/lv_swap

It returns the error as below.

[root@HA---------S ~]# xfs_growfs  /dev/vg_osdisk/lv_swap
xfs_growfs: /dev/vg_osdisk/lv_swap is not a mounted XFS file system

I have tried to run the below command to check the type of file system. Here it shows XFS only.

 [root@HA---------S ~]# df -Th
Filesystem                    Type      Size  Used Avail Use% Mounted on
/dev/mapper/vg_osdisk-lv_root xfs        72G  5.9G   66G   9% /

But I can see my 200G space as below.

[root@------------S ~]# lsblk
NAME                  MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
fd0                     2:0    1     4K  0 disk

│ └─vg_osdisk-lv_home 253:2    0    20G  0 lvm  /home
└─sda3                  8:3    0   200G  0 part

sr0                    11:0    1  1024M  0 rom

So how can I increase the space of the new logic system to the existing partition disk.

Solution

The /dev/vg_osdisk/lv_swap is a part of swap area (as used already logical volume) and cannot be expand xfs_growfs command.

The sda3 (207.9G) partition is already assigned as a part of swap area.

If you want to increase OS filesystem area, you must decrease swap area(reduce swap logical volume) with swapoff command, and extend lv_root or lv_home logical volume and then extend xfs filesystem xfs_growfs /dev/v_osdisk/lv_root or xfs_growfs /dev/v_osdisk/lv_home.

lv_swap sounds like a swap partition. swap partitions don't have a file system.

I think you resized the wrong logical volume. 200GB swap doesn't make much sense.

@GeraldSchneider yeah man.. Now i realized that i resized the wrong volume. Instead of /dev/vg_osdisk/lv_root, I resized the /dev/vg_osdisk/lv_swap volume. So how can I rollback from this..

@GeraldSchneider Thanks for pointing me in a right direction..

Thanks a lot buddy.. By mistake, i have extended the wrong partition... Your solution helped a lot.. Thank you once again..
