How to find cause of main file system going to read only mode
- by user606521
Ubuntu 12.04
File system goes to readonly mode frequently.
First of all I have read this question file system is going into read only mode frequently already.
But I have to know if it's not caused by something else than dying hard drive. This is server provided by my client and I am just runing there some node.js workers + one node.js server and I am using mongodb.
From time to time (every 20-50h) system suddenly makes filesystem read only, mongodb process fails (due read-only fs) and my node workers/server (which are started by forever) are just killed.
Here is the log from dmesg - I can see there some errors and messages that FS is going to read-only, and there is also some JOURNAL error but I would like to find cause of those errors..

SMART support is: Unavailable - device lacks SMART capability.
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.
What I am doing wrong? Same is for sda2.
Morover now when I type any command that not exists in shell I get this:
