还在[回收站](../../recycle/SHOW-CATALOG-RECYCLE-BIN.md)中，可以清空回收站后，再等待
- 当前 BE 上的 tablet 太大，导致在迁移单个 tablet 时，一直因为超时而无法将这个 tablet 迁移走，可以调整 FE
Master 的配置`max_clone_task_timeout_sec`为一个更大的值（默认为 7200 秒）
- 当前 BE 上的 tablet 存在未完成的事务，可以等事务完成或手动中止事务
- 其他情况可以在 FE Master 的日志过滤`replicas to decommission`关键字，找出异常的 tablet，使用[SHOW
TABLET](../../table-and-view/data-and-status-management/SHOW-TABLET.md)语句找到该
tablet 所属的表，然后重新建一张新的表，将数据从旧表迁移至新表，最后使用[DROP TABLE

4. If the progress of the DECOMMISSION operation gets stuck, specifically, the
`TabletNum` column in the [SHOW BACKENDS](./SHOW-BACKENDS.md) statement remains
fixed at a certain value, it may be due to the following situations:
- There is no suitable other BE to migrate the tablets on the current BE.
For example, in a 3-node cluster with a table having 3 replicas, if one of the
nodes is to be decommissioned, this node cannot find other BEs to migrate the
data (the other two BEs already have one replica each).

+ - The tablets on the current BE are still in the [Recycle
Bin](../../recycle/SHOW-CATALOG-RECYCLE-BIN.md). You can empty the recycle bin
and then wait for decommission.
- The tablet on the current BE is too large, causing the migration of a
single tablet to always timeout and unable to migrate this tablet away. You can
adjust the configuration `max_clone_task_timeout_sec` of the FE Master to a
larger value (the default is 7200 seconds).
- There are unfinished transactions on the tablets of the current BE. You
can wait for the transactions to complete or manually abort the transactions.
- In other cases, you can filter the keyword `replicas to decommission` in
the logs of the FE Master to find the abnormal tablet, use the [SHOW
TABLET](../../table-and-view/data-and-status-management/SHOW-TABLET.md)
statement to find the table to which this tablet belongs, then create a new
table, migrate the data from the old table to the new table, and finally use
the [DROP TABLE FORCE](../../table-and-view/table/DROP-TABLE.md) to delete the
old table.
