Hi, I also have the same problem. I have used a 8GB Sd card on Banana pi m1 with OMV. I get the same message in my system logs.
Oct 5 03:28:26 bananapi monit[1187]: 'fs_srv_dev-disk-by-id-ata-ST4000DM000-1F2168_Z301XBJY-part1' space usage 85.8% matches resource limit [space usage>85.0%]
Oct 5 03:28:26 bananapi monit[1187]: 'rootfs' space usage 89.2% matches resource limit [space usage>85.0%]
When I check the filesystems
It shows two mounted drives
/dev/mmcblk0p1 ext4 total 57.97, used 24.07 MiB
/dev/mmcblk0p2 btrfs total 863.00, used 547.12 MiB
I’m new to omv, please can you explain why the SD size was shrunk down from 8GB, and help me if there is a way to fix.
I used “Etcher” to create the bootable sd card. Running OMV 3.0.87 (Erasmus)
