So I have a small Lenovo M720q with only one M.2 512Gb SSD drive, with about 70Gb of data. I use it for various dockers. After some weeks now with frequent reboots I suspect that it is going bad. To test this I have added a temporary 2.5" 128Gb drive to my Lenovo. It is big enough for my data, but since it is not bigger, as I understand it, I can't just add it to the array and remove the 512Gb drive.

What would be the right procedure to move all my data to the 128Gb drive, disable the 512Gb drive, and then let the system run as normal and see if the daily reboots stop?

Thank you for the help.

We need more details, do you have parity? are both running on the array? Or just post the diagnostics.

Thank you for the reply.

I only have one disc. No parity, nothing more. One disc in the array.

And then I now added one more that is unassigned. That I would like to move everything to, even though it is smaller, but big enough for the data I have. So I can disconnect the possible faulty one, and see if that is the problem.

But I can also add the diagnostics if that helps.

You can assign the new disk to the array as well, copy/move all the data from one to the other, then do a new config to remove the old one.

Ok, it is that easy? I thought that if I add a disk it just add the storage to the array and they work together and I can't chose where the data is stored? That the two disks will be treated as one.

Array disks are separate filesystems, you can copy the data from one to the other using the built-in file manager, for example.

Thank you for the help. Everything seems to be working. Now back to waiting to see if it was the bad disk that caused the reboots.

Not very common, but not impossible.
