Description Oliver Ilian 2019-05-03 07:41:29 UTC 
Description of problem:
When trying to grow an XFS filesystem, I get an error:

xfs_growfs: /dev/mapper/RHEL7CSB-Root is not a mounted XFS filesystem


Version-Release number of selected component (if applicable):
RHEL 8
xfsdump-3.1.8-2.el8.x86_64
xfsprogs-4.19.0-2.el8.x86_64


Steps to Reproduce:
1. [root@ohaessle ~]# df -h | grep Root
   /dev/mapper/RHEL7CSB-Root   49G  6.9G   42G  15% /

2. [root@ohaessle ~]# lvresize -L +50G /dev/mapper/RHEL7CSB-Root
      /dev/sda: open failed: No medium found
      Size of logical volume RHEL7CSB/Root changed from 50.00 GiB (12800 extents) to 100.00 GiB (25600 extents).
      Logical volume RHEL7CSB/Root successfully resized.

3. [root@ohaessle ~]# xfs_growfs /dev/mapper/RHEL7CSB-Root
     xfs_growfs: /dev/mapper/RHEL7CSB-Root is not a mounted XFS filesystem


4. [root@ohaessle ~]# xfs_info /dev/mapper/RHEL7CSB-Root
     xfs_info: /dev/mapper/RHEL7CSB-Root contains a mounted filesystem

     fatal error -- couldn't initialize XFS library


Actual results:
I can not get info or extend an xfs partition

Expected results:
Partition + FS should be extended to 100GB
Comment 1 Eric Sandeen 2019-05-03 14:03:55 UTC 
SYNOPSIS
       xfs_growfs [ -dilnrx ] [ -D size ] [ -e rtextsize ] [ -L size ] [ -m maxpct ] [ -t mtab ] [ -R size ] mount-point

Point xfs_growfs at the mountpoint, not the device.
Comment 2 Eric Sandeen 2019-05-03 14:26:34 UTC 
(ditto for xfs_info, btw)

Newer versions may be more flexible here, but for now, it's behaving as documented in the manpages.
