You need to show fstab. Systemd owns raid and its entry is not working. It will overrule you and unmount anything you put there since it thinks it owns it. On Sun, May 24, 2020, 12:36 PM Patrick O'Callaghan wrote: > On Sun, 2020-05-24 at 19:29 +0200, Alexander Dalloz wrote: > > > > Generally yo

His issue was he did the manual mount on /raid (already in fstab with a different device) and systemd immediately unmounted it. The mount succeeds with no error, and the umount happens so fast you are left confused about what is going on.It did at least note it in messages so long as you can g

Both spinning disks? No SSD's involved? On the upgrade it will have to read the packages from disk and then write them back to the same disk at a different location as files, this will cause a lot of extra seeking (maybe 2x slower here) The laptop drive may be a lower RPM than the other machine d

You might run a smartctl --all /dev/ and see if the disk is reporting issues with sectors. A few slow but still readable sectors would push up the time. On Fri, May 29, 2020 at 1:25 AM Michael D. Setzer II via users wrote: > > > On 2020-05-29 01:58, Michael D. Setzer II via users wrote: > >> I'v

One complication. You said you aren't using a HUB, that is probably not exactly true. Almost all of the USB ports on a laptop or a desktop are using a HUB, very few of the ports are dedicated. Typically a laptop or desktop has at most 3 actual real underlying ports, and some do not even have that
