# How to replace the SSD in LambdaQuad?

## post by Karun on Jan 28, 2022

I am in a situation where the main **SSD in my LambdaQuad (4 GPU workstation server) is in danger of dying**.

I see the following error message once in a while:

**EXT4-fs error device nvme0n1p2 ext4-find-entry:1455 inode: nnnnnn**  
**System_Journal ID [nnn]: Failed to write entry…**  
It is giving me warning.

After rebooting the **smartctl** says the device “PASSED”.  
But I suspect better replace now than wait for it to crash.

The OS is Ubuntu 20.04.

The SSD details:

Model Number: **Samsung SSD 970 EVO 1TB**  
Serial Number: **S46DNF0K504699M**

How to replace it and avoid reinstalling the OS (Ubuntu 20.04)?

Thanks,

Karun

I meant **smartctl --all /dev/nvme0n1p2** says the  
**SMART overall-health self-assessment test result: PASSED**

We have a ticket on this. It will be helpful to have the:

smartctl -x /dev/nvme0

Also it may be you just need to run fsck. I am waiting on data to determine how/why the data was corrupt. (inode is basically a pointer to a file).

Either way it is best to back up your data sooner.

- This will show previous errors, temperatures over threshold, etc.

For copying there are a few ways…

1. The hold ‘hack’ way
   - a. Copy the partition table
   
     dd if=/dev/olddev of=/dev/newdev
     
     where olddev/newdev are your actual device names
     
     Control-C after a few seconds (copies the partition tables)
     
     Or you can use fdisk, parted, gparted to create the same partitions.
   - b. mkfs/Mount the partitions
   
     - mkfs the new partitions
     - mount the partitions
     - Then use cp -ax or find . | cpio -pdum directory

2. Use one of the tools… I will test clonezilla and gparted to do the moves.
   
   [https://clonezilla.org/](https://clonezilla.org/)  
   [GParted -- GParted Manual](https://gparted.org/display-doc.php?name=help-manual&lang=C)

* Again I will test these.

Normally I just do a fresh install, and copy over the home or data directories.
