I'm copying about 800Gb of data between a samba share and a local usb attached ext4 hard drive. I'm about halfway through, and I've noticed that after a couple of hours of copying any command that I run results in (for
-bash: /bin/ls: No such file or directory Bus error
This SO answer talks about the hardware being unable to address memory anymore, and this Quora answer also points out that the issue is related to memory being unavailable. However, there isn't any good advice on how to fix/avoid the issue, or whether it is symptomatic of a more broader underlying problem.
The first time it happened I rebooted the Pi in question and restarted the copy (with no-clobber
-n switch), and the system went back to normal for a few hours. Now I'm getting the same issue again. Is anyone else experiencing this, and is there any advice for avoiding/fixing?
The Pi is attached to a 1.2A capable wall plug, external HDD is independently powered and is connected to the Pi by a powered USB hub.
