Cryptsetup for burn-in test of large HDDs?

I, personally, would be fine with a single pass of zeros and checking to see if any writes failed. As @dan mentioned above, SMART will pick up any read/write errors along the way, which can be reviewed with smartctl.

Some form of burn-in is recommended, but not necessary, and you fully get to define what to do and what you deem to qualify as “enough”.

You’re right of course, it’s my decision how much I want to stress them.

@etorix

You do not have to do it on your main NAS, and certainly not by taking down the pool.

Well, my problem is not enough power (on the 5v line, which is why I’m switching from 5*2,5 inch to a mirror of 3,5 inch drives, but that is a different story) so I had to take down the pool to test the new drives.

Anyway, I settled on one pass of badblocks. But now I find that I can’t run tmux. I get the error mentioned in this thread (with zsh, but the same on any shell). Now I’m hesitant to do it without a way to reattach in case the ssh session is closed…

@etorix

Triple-check any destructive command before hitting “Enter”, it’s a good habit…

Always good advice!
