linux ext4-fs error,[求助]EXT4-fs error (device sdb4) ext4_find_entry

简介: linux ext4-fs error,[求助]EXT4-fs error (device sdb4) ext4_find_entry

刚做了一下fsck,也没有严重的问题。btw,这是个800GB的Intel SSD企业盘。

# fsck.ext4 -f /dev/sdb4
e2fsck 1.43.4 (31-Jan-2017)
Pass 1: Checking inodes, blocks, and sizes
Inode 47185925 extent tree (at level 2) could be narrower.  Fix? yes
Inode 47185926 extent tree (at level 2) could be narrower.  Fix? yes
Pass 1E: Optimizing extent trees
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/sdb4: ***** FILE SYSTEM WAS MODIFIED *****
/dev/sdb4: 18/47529984 files (0.0% non-contiguous), 20235838/190109905 blocks

2/24追记:

事实表明上述fsck的修复并不妨碍故障再次发生。

每次故障发生的时间点

2/09 21:00 首次出现

2/14 03:00

2/15 14:00

2/20 19:00

2/24 17:00

每次故障发生的时间并非正点,而是在正点附近,在该时间点前,系统的负载并没有明显波动。

每次故障的时间间隔大约四五天,只有2/14和15例外。


2/26追记:

周日去机房检查了一下硬件,怀疑该SSD SATA口松动,换到另一个板上SATA,有待观察……

最后的话

最近很多小伙伴找我要Linux学习资料,于是我翻箱倒柜,整理了一些优质资源,涵盖视频、电子书、PPT等共享给大家!
