nikkoaki Posted June 8, 2021 Posted June 8, 2021 So, i set up an OrangePi PC with armbian just to run pihole+unbound about 4 or 5 months ago. Out of curiosity i ran cat /sys/fs/ext4/mmcblk0p1/lifetime_write_kbytes 31366225 That's 31GB written on the 8GB sd card which is almost empty df -h Filesystem Size Used Avail Use% Mounted on udev 430M 0 430M 0% /dev tmpfs 100M 11M 90M 11% /run /dev/mmcblk0p1 7,2G 1,7G 5,4G 24% / tmpfs 500M 3,5M 497M 1% /dev/shm tmpfs 5,0M 4,0K 5,0M 1% /run/lock tmpfs 500M 0 500M 0% /sys/fs/cgroup tmpfs 500M 8,0K 500M 1% /tmp /dev/zram1 59M 8,4M 46M 16% /var/log tmpfs 100M 0 100M 0% /run/user/999 tmpfs 100M 0 100M 0% /run/user/0 Checking the data written since the last reboot 91 days ago awk '/mmc/ {print $3"\t"$10 / 2 / 1024}' /proc/diskstats mmcblk0 11032.2 mmcblk0p1 11032.2 11GB in 91 days. I checked the logs. Nothing out of the ordinary. The biggest files are the pihole logs (around 5MB per log which rotates daily) iotop -a shows that journaling writes about 1MB of data per hour to the disk.. that's still only 2GB per 91 days Is there a good way to see what exactly is writing so much to the SD card? Thanks in advance.
