Dell Latitude 7490 with existing SATA m.2 SSD. We want to upgrade to larger NVMe drive (Crucial 1Tb).
First tried new drive in Startech NVMe USB enclosure (M2E1BMU31C). Downloaded Crucial cloning software (locked version of Acronis). Problem – not recognised as Crucial drive so Acronis won’t run.
Posts suggest that the new drive should be installed in the laptop first and the system booted via USB. So take current drive out and put it in a SATA USB m.2 enclosure. Attach this to USB-C port and reboot.
This doesn’t work. What does work is attaching it to a USB-A port instead. Then it boots with no intervention.
After that the disk was clones (with no reboot necessary!), the old dive disconnected and the system booted happily from the new drive.
Setup – Dell Latitude 7490 running Ubuntu 18.04 Bionic and Dell WD15 USB-C dock.
Problem – system freezes when dock unplugged.
This problem started after updates. The solution found was to revert to the previous kernel (4.15.0-43-generic) from 4.15.0-44-generic. Did this by setting GRUB to remember the boot setting – change /etc/grub/grub with:
Then hit esc at the loading screen to get to the grub menu.
Installing Windows Server 2012 R2 on a Dell PowerEdge R520. Initially had problems with the “We couldn’t create a new partition or locate an existing one” error. Fixed by going into the bios and changing the boot order so that the internal SD card module came second rather than first (which was needed to make it boot from the SD cards).
Installed FreeNAS 9.3 on Kingston Ultimate 16 Gb cards on dual SD module in Dell R520 (took ages – so did card synchronisation when first inserted). Came up as boot device missing initially on reboot. Changed hard drive order in the bios to put SD cards first and it booted ok.
Update the repository lists, and then install the relevant package:
apt-get install megaclisas-status
Running megaclisas-status should then give the status of the array(s). The script is set up by default to email root every two hours if there is a problem. These defaults can be overridden using a defaults file:
You need to create this if necessary. The defaults are:
MAILTO=root # Where to report problems
PERIOD=600 # Seconds between each check (default 10 minutes)
REMIND=7200 # Seconds between each reminder (default 2 hours)
(can be found in)
If you have the system set up to divert root email to you then it should just work.
Interesting little wrinkle setting up a RAID5 on 4x4Tb drives in a Dell PowerEdge R520 with a PERC H710 mini controller. Using the fancy integrated interface (F11) the first VD of 20 Gb is fine, but the second only allows just under 1Tb to be used!
Using the basic bios extension thingy (Ctrl-R) it works fine. Also, somewhat faster…
This should be a five-minute job, and if Dell used the standard mountings it would be. Guess what…
The T1500 has the mounting holes in the standard places for a LGA 1156 socket, but has screw bosses in these holes, presumably held there by a backing plate behind the motherboard. The stock heatsink screws into these with captive screws – springs hold the bracket down. In theory if the bosses were removed a standard heatsink would clip in, but this would require the motherboard to be removed. Alternatively, the screws with the ~2mm stand-off bits (from the old-style green plastic CD drive mounting rails with the anti-vibration mounts) fit and work quite well. Note the stand-off in these is not quite right, so you probably don’t want to tighten them fully – just enough to hold the heatsink down firmly (It’s best to lay the system down so that the heatsink can rest on the processor to fine-tune the position).
(Why not just replace the fan? Because although it’s a standard size (80x80x25mm) it’s a high airflow model. RS and CPC don’t have anything similar with a 4-pin plug. And as a new heatsink and fan could be got for less than a tenner (before shipping charges) from Misco…)
