Add support for numeric mergerfs references like "1:2" by mapping them
to actual mount points (/mnt/disk1, /mnt/disk2). This enables proper
mergerfs pool detection and hides individual member drives as intended.
Skip mergerfs pools with numeric device references (e.g., "1:2")
instead of crashing. This allows regular drive detection to work
even when mergerfs uses non-standard mount formats.
Preserves existing functionality for standard mergerfs setups.
1. Add missing _fs_ filter to usage_percent parsing in dashboard
2. Fix agent to use calculated fs_status instead of hardcoded Status::Ok
This completes the disk collector auto-discovery by ensuring filesystem
usage percentages and status indicators display correctly.
Remove unused debug code and fix device name parsing to properly
handle lsblk tree characters. This resolves the issue where only
/boot filesystem was discovered instead of both /boot and /.
Add debug logging to filesystem usage collection to identify why
some mount points are being dropped during discovery. This should
resolve the issue where total capacity shows incorrect values.
Replaced complex disk collector with simple lsblk → df → group workflow.
Supports both physical drives and mergerfs pools with unified metrics.
Eliminates configuration complexity through pure auto-discovery.
