1、/var/log/messages报错。[[email protected] ~]# tail -f /var/log/messages | grep error Aug 6 16:03:25 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 Aug 6 16:03:25 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 Aug 6 16:03:25 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 Aug 6 16:03:52 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 Aug 6 16:03:52 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 Aug 6 16:03:52 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 Aug 6 16:06:30 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032966 Aug 6 16:06:30 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032966 Aug 6 16:06:31 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032966 Aug 6 16:06:31 localhost kernel: EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032966 Aug 6 16:51:22 localhost dbus-daemon: [system] Rejected send message, 1 matched rules; type="method_call", sender=":1.25" (uid=42 pid=3675 comm="gnome-power-manager) interface="org.freedesktop.Hal.Device.LaptopPanel" member="SetBrightness" error name="(unset)" requested_reply=0 destination=":1.4" (uid=0 pid=2085 comm="hald)) Aug 6 16:51:22 localhost kernel: res 41/40:00:c8:12:9e/00:00:1d:00:00/40 Emask 0x409 (media error) <F> Aug 6 16:51:22 localhost kernel: ata1.00: error: { UNC } Aug 6 16:51:26 localhost kernel: res 41/40:00:c8:12:9e/00:00:1d:00:00/40 Emask 0x409 (media error) <F> Aug 6 16:51:26 localhost kernel: ata1.00: error: { UNC } Aug 6 16:51:29 localhost kernel: res 41/40:00:c8:12:9e/00:00:1d:00:00/40 Emask 0x409 (media error) <F> Aug 6 16:51:29 localhost kernel: ata1.00: error: { UNC } Aug 6 16:51:33 localhost kernel: res 41/40:00:c8:12:9e/00:00:1d:00:00/40 Emask 0x409 (media error) <F> Aug 6 16:51:33 localhost kernel: ata1.00: error: { UNC } Aug 6 16:51:33 localhost kernel: sd 0:0:0:0: [sda] Add.

2、/var/log/maillog邮件日志报错
[[email protected] log]# tail -f maillog | grep error
Aug 6 16:03:52 localhost dovecot: Error: pop3([email protected])<13489><mEvet79ybgm3C8re>: Mailbox INBOX: open(test.com.cn/0/wangyao/dovecot-uidlist) failed: Input/output error Aug 6 16:03:52 localhost dovecot: Error: pop3([email protected])<13489><mEvet79ybgm3C8re>: Mailbox INBOX: open(test.com.cn/0/wangyao/dovecot-uidlist) failed: Input/output error Aug 6 16:03:52 localhost dovecot: Error: pop3([email protected])<13489><mEvet79ybgm3C8re>: Mailbox INBOX: open(test.com.cn/0/wangyao/dovecot-uidlist) failed: Input/output error Aug 6 16:03:52 localhost dovecot: pop3([email protected])<13489><mEvet79ybgm3C8re>: Error: Couldn't init INBOX: Mailbox INBOX: open(test.com.cn/0/wangyao/dovecot-uidlist) failed: Input/output error Aug 6 16:03:52 localhost dovecot: pop3([email protected])<13489><mEvet79ybgm3C8re>: Couldn't init INBOX: Mailbox INBOX: open(test.com.cn/0/wangyao/dovecot-uidlist) failed: Input/output error top=0/0, retr=0/0, del=0/0, size=0
3、dmesg命令查看
ata6: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata6.00: ACPI cmd ef/10:06:00:00:00:00 (SET FEATURES) succeeded ata6.00: ACPI cmd f5/00:00:00:00:00:00 (SECURITY FREEZE LOCK) filtered out ata6.00: ACPI cmd b1/c1:00:00:00:00:00 (DEVICE CONFIGURATION OVERLAY) filtered out ata6.00: ACPI cmd ef/10:06:00:00:00:00 (SET FEATURES) succeeded ata6.00: ACPI cmd f5/00:00:00:00:00:00 (SECURITY FREEZE LOCK) filtered out ata6.00: ACPI cmd b1/c1:00:00:00:00:00 (DEVICE CONFIGURATION OVERLAY) filtered out ata6.00: configured for UDMA/133 ata6: EH complete EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 5772763 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 5772763 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 5772763 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032966 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032966 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032966 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032966 EXT4-fs error (device dm-2): ext4_lookup: deleted inode referenced: 6032967
4、扫描坏道,扫描到8%就这么多错误。
[[email protected] ~]# badblocks -s -v -o /root/badblocks.log /dev/sda 正在检查从 0 到 2930266583的块 Checking for bad blocks (read-only test): 8.48% done, 36:38 elapsed [[email protected] log]# cat /root/badblocks.log 248405248 248405264 248405265 248405266 248405267 248446536 248446568 248446569 248446570 248446571 248447968 248449368 248449380 248449381 248449382 248449383 249651992 249652052 249652053 249652054 249652055 249652056 249652057 249652058 249652059 249652060 249652061
5、果断换硬盘
备注:smartctl这个工具也可以扫描和修复坏道。
