前天 OVH 独服看到 197 Current_Pending_Sector 数值变成 1，然后用 badblock 扫描坏道果然发现了 4 个，我也没继续修复。只是开始备份数据准备找客服换硬盘。结果今天数据快拷完了重新检测了下发现 smart 197 又变成 0 了，重扫之前坏道的块也扫不到坏道了。这是怎么回事？HOH 2022-12-01 12:26 2 这个叫 unstable 251768938 2022-12-01 12:26 3 我觉得取决于扫描软件 28661 2022-12-01 12:27 4root@hostname:~# smartctl -l error /dev/sdbsmartctl 7.2 2020-12-30 r5155 [x86_64-linux-5.10.0-19-amd64] (local build)Copyright (C) 2002-20, Bruce Allen, Christian Franke, www.smartmontools.org=== START OF READ SMART DATA SECTION ===SMART Error Log Version: 1ATA Error Count: 20 (device log contains only the most recent five errors) CR = Command Register [HEX] FR = Features Register [HEX] SC = Sector Count Register [HEX] SN = Sector Number Register [HEX] CL = Cylinder Low Register [HEX] CH = Cylinder High Register [HEX] DH = Device/Head Register [HEX] DC = Device Command Register [HEX] ER = Error register [HEX] ST = Status register [HEX]Powered_Up_Time is measured from power on, and printed asDDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,SS=sec, and sss=millisec.
