rcourtman	bb798e18b6	fix(agent): find zpool binary on TrueNAS SCALE (#718) ... Enhanced zpool binary lookup to try common paths when exec.LookPath fails. This fixes issue #718 where TrueNAS SCALE reports inflated storage because the agent runs with a restricted PATH that doesn't include /usr/sbin. Changes: - Added findZpool() helper that tries common paths like /usr/sbin/zpool, /sbin/zpool, /usr/local/sbin/zpool for TrueNAS/FreeBSD/Linux systems - Added commonZpoolPaths variable listing typical zpool locations - Added tests for the new findZpool function This ensures zpool list is used for accurate pool-level capacity instead of falling back to dataset-level summation.	2025-12-18 16:23:56 +00:00
rcourtman	fb976acfc3	Add unit tests for ZFS storage utility functions (hostmetrics) ... 65 test cases covering 8 functions: - parseZpoolList: zpool command output parsing (15 cases) - uniqueZFSPools: pool name deduplication (7 cases) - bestZFSMountpoints: mountpoint selection logic (8 cases) - zfsMountpointScore: mountpoint scoring algorithm (7 cases) - zfsPoolFromDevice: pool name extraction (6 cases) - calculatePercent: percentage calculation (7 cases) - clampPercent: value clamping (8 cases) - bestZFSPoolDatasets: dataset selection (7 cases) First comprehensive unit test coverage for internal/hostmetrics package ZFS utilities.	2025-11-30 12:50:58 +00:00
