Use dumpe2fs or tune2fs -l to see the UUID on ext[234]fs, or xfs_admin -u on xfs. -- Kenyon Ralph signature.asc Description: Digital signature -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

What I dont know is that the UUID will change when you change the sata mode, you can check it out with blkid(8). Another way is using the by-id or by-path format, check /dev/disk/by-* -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

I thought it wasn't set because a samba performance issue, but it goes away after reboot ... I hope this issue has gone definitely.

The only thing I'd check is that /etc/fstab mounts using UUIDs and not /dev/sd? names.

Change SATA mode to AHCI on installed server
I want to change SATA mode on a server already installed. Should I take care of something before make the change at the BIOS setup?
