Shell

$ lncli deletepayments --all --help

NAME:
   lncli deletepayments - Delete a single or multiple payments from the database.

USAGE:
   lncli deletepayments [command options] --all [--failed_htlcs_only --include_non_failed] | --payment_hash hash [--failed_htlcs_only]

CATEGORY:
   Payments

DESCRIPTION:
   
  This command either deletes all failed payments or a single payment from
  the database to reclaim disk space.

  If the --all flag is used, then all failed payments are removed. If so
  desired, _ALL_ payments (even the successful ones) can be deleted
  by additionally specifying --include_non_failed.

  If a --payment_hash is specified, that single payment is deleted,
  independent of its state.

  If --failed_htlcs_only is specified then the payments themselves (or the
  single payment itself if used with --payment_hash) is not deleted, only
  the information about any failed HTLC attempts during the payment.

  NOTE: Removing payments from the database does free up disk space within
  the internal bbolt database. But that disk space is only reclaimed after
  compacting the database. Users might want to turn on auto compaction
  (db.bolt.auto-compact=true in the config file or --db.bolt.auto-compact
  as a command line flag) and restart lnd after deleting a large number of
  payments to see a reduction in the file size of the channel.db file.
  

OPTIONS:
   --all                 delete all failed payments
   --payment_hash value  delete a specific payment identified by its payment hash
   --failed_htlcs_only   only delete failed HTLCs from payments, not the payment itself
   --include_non_failed  delete ALL payments, not just the failed ones
