缺省情况下,zpool status 命令仅说明已出现损坏,而不说明出现此损坏的位置。例如:
# zpool status monkey
pool: monkey
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

scrub: scrub completed after 0h0m with 8 errors on Tue Jul 13 13:17:32 2010
config:
NAME STATE READ WRITE CKSUM
monkey ONLINE 8 0 0
c1t1d0 ONLINE 2 0 0
c2t5d0 ONLINE 6 0 0
errors: 8 data errors, use '-v' for a list

每个错误仅指示在给定时间点出现了错误。每个错误不一定仍存在于系统上。一般情况下是如此。某些临时故障可能会导致数据损坏,故障结束后会自动修复。完整的池清理可保证检查池中的每个活动块,因此每当清理完成后都会重置错误日志。如果确定错误不再存在,并且不希望等待清理完成,则使用 zpool online 命令重置池中的所有错误。
如果数据损坏位于池范围内的元数据中,则输出稍有不同。例如:
# zpool status -v morpheus
pool: morpheus
id: 1422736890544688191
state: FAULTED
status: The pool metadata is corrupted.
action: The pool cannot be imported due to damaged devices or data.

config:
morpheus FAULTED corrupted data
c1t10d0 ONLINE

如果出现池范围的损坏,池将被置于 FAULTED 状态,这是因为池无法提供所需的冗余级别。
