...support VM formats (VBox, VHD and VMWare) easily? Is this an xfs filesystem or an ext4 filesystem? I could be wrong, but I suspect that e2label would only work on an ext2/3/4 filesystem. The default filesystem in RHEL/CentOS 7 is xfs. It looks like you can check labels on xfs filesystems with xfs_admin -l </path/to/filesystem> and you can set a label on an xfs filesystem with xfs_admin -L "<your label>" </path/to/filesystem> If you run "blkid" on your system it will give you all labels for all disks connected to your machine for any filesystem types that...

I had to unmount the boot partition (being in Troubleshooting mode), run the above command, which provided a new UUID and at last the partition was recognized as xfs.

After more googling, I found this bug report with a very recent fix: https://bugzilla.redhat.com/show_bug.cgi?id=1399487 It seems to me that this may be relevant in our case. If so, may it be that this fix has not been rolled out to CentOS repos yet? What is your opinion and your
