help

Is this error affecting?，what should I do？

How are your disks mounted? Are they directly attached SSDs, mounted over a NAS or is there a RAID involved? It looks like one of the files in /var/lib/influxdb/data/_internal/monitor/23 has a bad block. Since TSM files are immutable once written, this can occur because of hardware or filesystem issues.

It's not clear which specific file is problematic, but it is likely one of these 3:

[I] 2018-01-19T07:01:37Z compacting level 1 /var/lib/influxdb/data/_internal/monitor/23/000000003-000000001.tsm (#0) engine=tsm1
[I] 2018-01-19T07:01:37Z compacting level 1 /var/lib/influxdb/data/_internal/monitor/23/000000004-000000001.tsm (#1) engine=tsm1
[I] 2018-01-19T07:01:37Z compacting level 1 /var/lib/influxdb/data/_internal/monitor/23/000000005-000000001.tsm (#2) engine=tsm1

You can move those files out the directory and the error should go away.

The disk is broken ，thank you。

FYI influxdb will not recover from this at all it will just keep at it over and over killing your cpu, you have to remove the files afaik. fun
