我有一个ubuntu服务器设置了14磁盘ZFS raidz2池.
大约80％的时间,在重新启动时,我将最终得到一个降级池,其中两个磁盘标记为出现故障.出现故障的驱动器并不总是相同,但始终只有两个驱动器.例如：
$sudo zpool status
pool: tank
state: DEGRADED
status: One or more devices could not be used because the label is missing or
invalid. Sufficient replicas exist for the pool to continue
functioning in a degraded state.
action: Replace the device using 'zpool replace'.

我可以导出并重新导入池,磁盘不再出现故障.例如：
$sudo zpool export tank
$sudo zpool import tank
$sudo zpool status
pool: tank
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced,and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.

正在使用的HBA在另一台服务器上正常工作.
还有什么我可以尝试在重启时避免这些故障驱动器吗？我有另一个我可以交换的HBA.
