I have 3 hard drives and two of them are xfs and one (for historical reasons) is ext4. Without going into any war about which filesystem is better, suppose that I want to change the sda1 hard disk from ext4--->to xfs. I have plenty of space so I can move its present content somewhere else.
Is there any easy way to do it and remount everything back as it is?
I simply want to have xfs everywhere.
Cheers

I did this with gparted, but now the workstation complains because it does not find the disk and starts only in emergency mode (no graphical interface).
Any idea about how to fix this?
Thanks!
I do not know anything about the UUID. I just used gparted naively thinking that I could not do too much damage since I did not touch the hdd with the operating system installation. It is possible that gparted changed it, but I did not do it willingly.
You will probably need to edit /etc/fstab to use the new UUID. You can use nano or whatever command-line text editor you have installed to do that. First, get the UUID with blkid as root, copy that UUID, and paste it to the appropriate line in fstab. It should then boot. You can add nofail to the options if you want, to prevent boot failure if it's not present for some reason. If you really want to use a GUI for most of the editing, just comment the line for sda1 by inserting # as the first character in the line, boot to your desktop, and then edit fstab as root with whatever text editor you like. I find it easier to use nano, but that's just my preference.
Thanks, finally due to time constraint, believe it or not, it was faster to reinstall.
I will call this experience (a good naming for your own mistakes).
Yes, a reinstall is usually faster, unless you have a lot of data that has to be retained. Even so, a full backup, reinstallation, and returning the data is usually faster. Each situation is a little different, though.
