xfs_growfs -d fails

SUSE Linux Enterprise Server SLES Configure-Administer

I am running SLES12 and I attempting to increase the size of the / directory. The directory is a LVM xfs volume. However, when I execute xfs_growfs -d / the LVM volume is unchanged.

Hi mikenash,

you don’t show any information about the LV the root fs is on - was it’s size increased (i.e. via “lvresize -L+someM /dev/system/root”) before trying to extend the file system on that LV?

Regards,
Jens

Hello Jens, thank you for the reply. I found out the solution was to lvextend the container first and then do the xfs_growfs.
