2 weeks ago, my BTC full node (raspberry) crashed. I thought it was du to my sdcard. But after testing the sdcard, all the results were just fine. On this saloon, i posted my situation and someone told me i could give a try with this config , as shown below:

tmpfs /tmp tmpfs defaults,noatime,nosuid,size=500M 0 0 tmpfs /var/log tmpfs nosuid,nodev,mode=0755,size=50M 0 0 tmpfs /var/tmp tmpfs nosuid,nodev,size=10M 0 0 tmpfs /var/log/nginx tmpfs nosuid,nodev,nosuid,mode=0755,size=20M 0 0 tmpfs /var/www/ tmpfs nosuid,nodev,mode=0755,size=10M 0 0

Which i did but in order to avoid any issue, i changed the sdcard.

But since 3 days, my raspberry does not act correctly (slow, hang suddenly, last night it crashed).

So ,now i ve decided to follow most of the comments which is to use an Hard Drive instead of sdcard, cause I/O.

Now i ve to build it once more but for goods and cross my fingers :)
