I have two external drives attached to my Ubuntu Server 22.04.3. My /etc/fstab includes, among other things, the following two lines for the two drives:

/dev/disk/by-uuid/d7dbea69-0332-4d12-b905-b9a116e28422 /sandisk ext4 auto,nofail 0 2
/dev/disk/by-uuid/06b24834-a749-4d93-b0d5-a6da71eaf224 /verbatim ext4 auto,nofail 0 2

/verbatim is an independently powered magnetic disk also attached via USB. It gets detected and mounted on boot just fine. /sandisk is the problem. This is a USB SSD drive with no power. I can mount it fine after boot with mount -a but the system always boots with it not mounted. Is there any way I can have it mounted at boot?

  • What does your system log show about attempts by the system to mount it on boot?

  • Since it derives power through USB, try using a powered USB hub. Could be that at the instant of startup, there is in insufficient power.

My kernel ring buffer contained all the information I needed.

$ sudo dmesg
...
[    2.770637] usb 2-1: New USB device found, idVendor=0781, idProduct=55af, bcdDevice=40.55
[    2.770642] usb 2-1: New USB device strings: Mfr=2, Product=3, SerialNumber=1

...
[   60.108257] EXT4-fs (sdb): warning: mounting fs with errors, running e2fsck is recommended
[   60.125838] EXT4-fs (sdb): mounted filesystem with ordered data mode. Opts: (null). Quota mode: none.

So it was being detected during boot! A simple sudo e2fsck -y /dev/sdb fixed the problem.
