Running badblocks on multiples drives with tmux...

[Mr_N]

Is there a limit to the number you can run at once?

I have 4 new drives i'm burning in and badblocks appeared to start fine on 3 of the drives but when i started the 4th (all on same HBA) it started to throw write errors while the other 3 continued without any.
This is after all 4 drives passed long smart tests without any errors.

annoying thing is i cant open the shell from the gui to cancel the last badblocks cmd :/

the reporting graphs for the 3 drives show solid writes and the one with errors almost no writes.

No.

For instance, I happily ran six simultaneous instances when I first burned-in my drives.

Doesn't mean that much. I'm assuming they hadn't been used before, so it's normal that errors will start popping up once real use starts.

What do you mean? Are you trying to use tmux on the web shell? That's not a very good idea.

You should be able to login via SSH and use tmux attach to reacquire your tmux session.

yeah i was lazy using web shell :)

stopped the badblocks via ssh and no more errors, have set another short and long smart test on the offending drive to see whats what

below is what it was spamming me with for the last few hrs

Code:

(da6:mps1:0:0:0): Field Replaceable Unit: 0

I've done 24 drives simultaneously... no problems. Just watch the load average. I wouldn't recommend that wide on a CPU-limited box.

As for that drive you posted above... it's not looking good...
