I’ve been through Wiki and forum but cannot find simple explanation. Which I need because am lousy under-the-hood user despite being on Linux for over 10 years.
I have 3 drives in my Thinkpad W530:
An internal under-the-32GBRam 500 GB SSD (sdc). This is where my daily driver Gnome Manjaro used to be (well, it still is but it started malfunctioning recently to the point of being almost unusable, but that’s another story).
A 2 TB Data drive (sdb) inserted into the DVD Rom space using a container for that purpose. I have used this for 2 years without problem.
A new third drive, a 250 GB SSD (sda).
After trying many other distros because 2 weeks ago pacman was not working so every Manjaro install I tried - and every other Arch - was a mess, I returned to Manjaro Gnome 2 days ago and finally had a successful installation and got everything up and running again just like it used to be on the old Gnome OS have been using for almost 2 years.
Except getting the 2TB drive (sdb) to mount at startup.
(This has most of my data - plus most important stuff synced into a pCloud drive for I don’t really use the Home Directories).
When I go into ‘other locations’ in Nautilus, it mounts every time, no problem, but I cannot find out how to automount it on rebooting even though in Disks it is set to automount and it always used to do so just fine in the other system.
Note: this 2TB drive has 3 partitions, this being the first and main one (1 TB). That’s a change I made. (The other two partitions are for timeshift BU’s, one partition for the now almost dysfunctional daily driver Timeshifts, the other partition for the newly installed and seemingly working well (sda) system. I like to have two OS’s on hand in case OS1 craps out - as recently has been happening.)
Now maybe having 3 partitions is an issue, but I don’t believe it should be. In any case, in Disks it says that this first partition in the 2TB drive is auto mounting on startup, but it never does and I cannot find clear instructions anywhere on how to make this simple thing happen.
In Disks it says:
Mount at System Startup (checked)
Show in User interface (checked)
Require additional authorization section: all unchecked. Then:
Mount Point: /mnt/ec4a266c-f6e1-497c-91ab-af62b4230b7a
Identify as: /dev/disk/by-uuid/ec4a266c-f6e1-497c-91ab-af62b4230b7a
(I have tried identifying it as its name Label = 2TBData, but it makes no difference.)
Filesystem type: Auto
In the initial Disks Menu before you enter Settings to Edit Mount Options, it says:
Content: Ext 4 (version 1.0) - Mounted at: run/media/‘my user name’/2TBData.
Could some kind soul please tell me what specific steps I need to do in order to automount this partition at startup?
PS I went into Fstab and added the line:
UUID=ec4a266c-f6e1-497c-91ab-af62b4230b7a / ext4 defaults,noatime 0 0 (or 2)
but all that happens is that after Restart the disk doesn’t show up at all in Files so I cannot mount it by clicking on the icon.
The full fstab is: (with the 2TB uuid line ###-ed out)
UUID=fe64b8e5-27ee-4109-9270-431f953e2291 / ext4 defaults,noatime 0 1
#UUID=ec4a266c-f6e1-497c-91ab-af62b4230b7a / ext4 defaults,noatime 0 0
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
