My BananaPi has become very slow over the last few weeks. Often top
reports load average: 1.02, 1.06, 1.14
or much much higher numbers. And stats for idle CPU and I/O wait times are really high 40 id, 10 wa
.
I've checked a few other things such as iotop
and free -m
but haven't found one particular process that is causing the brunt of the problems.
At a guess I think the SD card might be failing.
How can I verify if this is the case. Or should I just buy a new SD card and backup my current one ASAP?
If it were failing, I'd expect programs to be forced to wait longer for disk access, if anything. What do you mean by "slow" anyway, just higher load averages? I don't see how they're related directly to the sd card. At any rate, sd cards are relatively cheap, just copy everything (

on another system) onto a new one and give it a try. – Xen2050 – 2017-08-24T13:20:47.240Often the top usage nunbers have been 4+ for overall CPU stats in 1, 5 & 15 mins. And when accessing ftp, SSH and samba shares they'll often timeout because the system is under too much stress for some reason. – juliushibert – 2017-08-25T08:59:21.967
