通过一个 shell 脚本获取了一个 token 变量。然后echo “header: $token http://xxx.corp.com” ，发现被 token 截断了。
终于发现 token 变量最后有一个

SMART 关键属性详解（监控硬盘健康的金指标） 硬盘健康监控的核心在于属性阈值（Threshold）与原始值（Raw Value）的对比。以下是生产环境中必须重点监控的 SMART 属性：
SMART 关键属性详解（监控硬盘健康的金指标） 硬盘健康监控的核心在于属性阈值（Threshold）与原始值（Raw Value）的对比。以下是生产环境中必须重点监控的 SMART 属性：
1. 致命级属性（立即故障预警） 属性名 ID 关键表现 处置动作 Reallocated_Sector_Ct 5 Raw > 0 (坏道重映射) 立即更换（即使值=1） Current_Pending_Sector 197 Raw > 0 (待修复扇区) 立即备份更换 End-to-End_Error 184 Raw > 0 (数据完整性错误) 即刻下线（静默损坏风险） Offline_Uncorrectable 198 Raw > 0 (无法修复扇区) 紧急替换 Reported_Uncorrect 187 Raw > 0 (无法纠正的读错误) 停止读写并更换 🔥 特征：一旦出现非零值，无论 normalized value 如何，硬盘已不可信。 2. 高危级属性（故障前兆） 属性名 ID 风险阈值 运维意义 Raw_Read_Error_Rate 1 Raw值持续上升 (原始读错误率) 磁头/介质退化早期信号 UDMA_CRC_Error_Count 199 Raw > 10 (接口传输错误) 检查线缆/RAID卡，超50即换盘 Seek_Error_Rate 7 Normalized < 阈值 (寻道错误) 机械定位精度下降 Power-Off_Retract_Count 192 Raw > 500/年 (异常断电次数) 磁头急停加速老化 High_Fly_Writes 189 Raw > 0 (磁头悬浮过高写入) 物理撞击/震动导致数据写偏 ⚠️ 特征：Raw 值异常增加或 Normalized 值跌破阈值，预示3个月内可能故障。 3. 寿命指标（老化评估） 属性名 ID 企业盘报废标准 说明 Power_On_Hours 9 > 40,000小时 超5年即进入故障高发期 Load_Cycle_Count 193 > 300,000次 磁头伸缩设计寿命上限 Temperature_Celsius 190/194 长期 > 45℃ 高温加速电路老化 G-Sense_Error_Rate 191 Raw > 1,000 物理震动损伤累积 📉 特征：数值越高，MTBF（平均无故障时间）呈指数级下降。 -

新观念
看到一个新观念，会觉得很有意思。
像“未来简史“里面说，普通人知道自己难免一死，所以愿意冒险做一些危险的尝试，但长生的人会更怕冒险，万一出了意外，代价会特别大。
这个观点，可以安慰自己这种普通人。。

梦
昨天梦到电子书的屏被压碎了。想到是7天无理由退货（其实压碎也不能退了，谁让是梦里呢）的最后几分钟了。赶紧拿出手机想退货。
可是APP改版了，我怎么也找不到订单在哪里，那种梦里面着急的感觉啊，你能体会到吗？
然后醒了，想到刚刚的梦，想到电子书还好好的。一下子开心轻松了。

"status": { "value": 0, "string": "Not_testing" } }, { "lba_min": 0, "lba_max": 0, "status": { "value": 0, "string": "Not_testing" } } ], "flags": { "value": 0, "remainder_scan_enabled": false }, "power_up_scan_resume_minutes": 0 } }分析如下
我们首先看一下硬盘的基本信息： 型号：HUH721010ALE600 序列号：JEJPJDPN 容量：10,000,831,348,736 字节（约10TB） 接口：SATA 3.2, 6.0 Gb/s 转速：7200 RPM 使用时间：54075 小时（约6.17年） 通电次数：23次 关键点分析： SMART状态：passed: true，表示SMART总体状态通过。 关键属性： Reallocated_Sector_Ct (ID 5): 原始值=0，表示没有重映射扇区。 Current_Pending_Sector (ID 197): 原始值=0，表示没有等待重映射的扇区。 Offline_Uncorrectable (ID 198): 原始值=0，表示没有离线无法修复的扇区。 UDMA_CRC_Error_Count (ID 199): 原始值=0，表示没有接口通信错误。 以上都是非常关键的健康指标，目前都为0，是良好的状态。 其他属性： Raw_Read_Error_Rate (ID 1): 原始值为0，正常。 Spin_Up_Time (ID 3): 原始值较大，但显示字符串为"442 (Average 405)"，说明自检的旋转时间在正常范围。 Start_Stop_Count (ID 4): 27次，通电次数23次，说明有几次可能是意外断电？但次数不多，且属性值100（最好100）正常。 Power_Cycle_Count (ID 12): 23次，与通电次数一致。 Power_Off_Retract_Count (ID 192): 2119次，这个属性表示磁头因意外断电而缩回的次数。通常这个值应该和通电次数接近，但这里通电次数只有23次，而磁头缩回次数达到2119次，这可能意味着硬盘经常意外断电（比如突然断电），或者是因为RAID卡频繁进行重置？需要关注。 Load_Cycle_Count (ID 193): 2119次，这个值通常表示磁头加载/卸载次数，对于台式机硬盘，设计值通常为30万到60万次，所以2119次不算高，但需要结合其他情况看。 Temperature_Celsius (ID 194): 当前温度为25°C，最高36°C，最低22°C，温度控制良好。 错误日志： 在ata_smart_error_log中，我们看到有5条错误记录（error_number从166到170），这些错误都发生在大约51289小时前（注意当前是54075小时，也就是大约2790小时前，约116天前）。 所有错误都是“UNC”（Uncorrectable Error）错误，发生在LBA 0（可能是日志记录问题，实际LBA可能不同）的读取操作中，错误发生时执行的命令都是FPDMA QUEUED（即NCQ读写）。 这些错误发生在51289小时，而当前已经54075小时，说明是过去发生的错误，而且没有新的错误发生。但是，为什么会有5次读取错误？这可能是因为当时有介质错误或者传输问题，但后续可能已经通过重试成功，或者没有再次发生。 自检日志： 最后一次自检是扩展自检（Extended offline）在18小时（从开始使用算起）完成且无错误，短自检在2小时时完成无错误。但注意，这些自检是很久之前做的（因为使用时间已经5万多小时），所以建议近期再做一次自检。 注意事项： 硬盘已经使用了超过5.4万小时，虽然关键属性都正常，但需要注意备份重要数据，因为任何硬盘在这个使用时间后风险都会增加。 错误日志中记录的错误虽然发生在过去，但也说明硬盘曾经出现过读取错误，这可能是一个早期警告。建议关注后续是否有新的错误出现。 另外，关于192属性（Power-Off_Retract_Count）和193属性（Load_Cycle_Count）都是2119次，而通电次数只有23次，这个比例很奇怪。通常，每次通电可能会有多次磁头加载/卸载，但2000多次相对于23次通电，平均每次通电要发生90多次，这有些偏高。可能的原因是硬盘经常进入节能模式（磁头缩回），或者是RAID卡频繁重置导致。虽然这个值本身并不代表故障，但频繁的磁头加载/卸载会消耗硬盘的机械寿命。 结论： 这块硬盘目前从SMART数据上看是健康的，但是使用时间已经很长（6年多），并且过去发生过读取错误，磁头缩回次数相对通电次数偏高。建议： - 运行一次完整的SMART自检（长测试）以确认当前状态。 - 密切关注硬盘的SMART数据变化，特别是重映射扇区和待处理扇区的数量。 - 确保重要数据已经备份，因为机械硬盘在长时间使用后故障率会上升。 - 如果可能，检查电源或RAID卡设置，以减少意外断电或硬盘重置的情况。 注意：由于该硬盘不在smartctl数据库（in_smartctl_database: false），一些属性（如ID 22）是未知属性，但我们分析的关键属性都是已知且正常的。 -
Disk State In Storcli
总结一下，在storcli64 /c0 show all的磁盘列表中，常见的物理磁盘状态有：
Onln: 在线（通常指已配置在虚拟磁盘中且正常工作） UGood: 未配置但良好 JBOD: 配置为直通磁盘 GHS: 全局热备 DHS: 专用热备 UBad: 未配置但故障 Offln: 离线（故障） Msng: 缺失 Rbld: 重建中 Pdgd: 预测故障（即将失效） Frn: 外来磁盘（带有其他控制器的配置） -
马来西亚-流水帐
6.1 凌晨1点飞吉隆坡，上午7点到达。
和曾可他们联系了好一会，怎么都找不到对方，发现不在一个航站楼。。
打车到酒店，寄存下行李（发现自己英语啥也听不懂），走去双子塔吃饭，一家网红餐厅，还不错。
然后打车去Best榴莲，吃了一个拼盘，然后又买了两个整个的。味道不错。价格比后面的沙巴以及国内便宜很多。
回酒店睡觉。晚8点，去夜市吃个海鲜。
吃完去双子塔看夜景，拍照。
6.2 上午飞亚庇，入住后，打车去网红餐厅，但关门了。就去了边上一家。吃完去订了后天的环滩岛。
然后去游泳池，泡一会，一边打游戏，一边等日落。
晚上去金潮海鲜吃饭，皮皮虾很大，也很贵。
6.3 上午无事，中午去另一家网红餐厅吃饭，结果还是关门。隔壁有家排着长队，感觉不错，进去吃了。味道一般。
下午海钓。船上晚餐。
然后去天桥下榴莲街。小摊不行，都骗人的。榴莲仔还行，就是价格和味道都不如吉隆坡。
6.4 没起来，环滩岛没去成。曾可他们去了。
我们中午吃了第一天想去的网红餐厅，然后按摩，再去咖啡店。
等曾可他们回来，去吃了最后一顿海鲜，敬文。价格美丽，味道也不错。
旁边有个榴莲摊，味道和价格都比榴莲仔略好一点。吃了两个。
