This may be more of a linux question, but I’m relatively Debian savvy and I can’t sort out what’s happening.
The output of df shows the sd card full. I’m not keeping anything on it other than the OSMC backup, which currently consumes 652MB, so I’m at a loss to understand what happened to the rest of the space.
/dev/mmcblk1p1 60G 60G 463M 100% /media/osmc_sd
drwxrwxrwx 1 osmc osmc 128K May 8 2019 .fseventsd
-rw-rw-rw- 1 osmc osmc 652M Jun 4 22:37 OSMCBACKUP_2021_06_04_22_33_05.tar.gz
drwxrwxrwx 1 osmc osmc 128K May 8 2019 .Spotlight-V100
.fseventsd is 512k and .Spotlight is 8M.
I’m not super familiar with OSMC’s use of the SD card, but can I format it without any ill effects?
