# --------------------------------- ZFS Pool Scrub ---------------------------------------------
|
||||
# -----------------------------------------------------------------------------------------------
|
||||
# Triggers a ZFS scrub on all pools (or a specific pool) and waits for completion.
|
||||
# Sends a notification when scrub completes with a summary of any errors found.
|
||||
#
|
||||
# ZFS scrub reads every block on every pool and verifies checksums — it catches
|
||||
# silent data corruption that would otherwise only surface when you try to read
|
||||
# the corrupted data. Running monthly is recommended for all ZFS pools.
|
||||
#
|
||||
# Usage:
|
||||
# zfs_pool_scrub.sh — scrub all pools
|
||||
# zfs_pool_scrub.sh poolname — scrub specific pool only
|
||||
# zfs_pool_scrub.sh --status — show scrub status for all pools
|
||||
# zfs_pool_scrub.sh --dry-run — show what would be scrubbed
|
||||
#
|
||||
# Pools in ZFS_REPORT_IGNORE_POOLS are skipped unless specified explicitly.
|
||||
# Scrub runs in background — script polls until complete then reports.
|
||||
# Safe to run while the pool is in use — scrub does not interrupt normal I/O.
