Ossim system startup Fault handling method

Ossim system startup Fault handling method

1. Issue background

Ossim is based on the Debian Squeeze 6 system, in its powerful processing capacity behind the fact that its system is relatively fragile, can not afford accidental power off, illegal shutdown and other serious unexpected operations. Doing so has a huge or even devastating effect on the system. Of course, we do not fear this failure of Linux, learning is a problem and solve the problem of the process, as long as master the basic ideas, all failures will be solved. There are many failures that cause Linux to fail to boot, such as/etc/initab,/etc/fstab configuration file loss or misconfiguration, root filesystem corruption, root partition corruption, grub loss or corruption, which can cause the system to fail to boot. The following example is a failure caused by a file system error due to an accidental power outage of the server, and the main workaround is to repair the file system by entering Linux resuce mode with Linux LiveCD.

2. Phenomena

Room of a Ossim server server in operation, accidental power down, a large number of data did not write back, and so coincidentally, Ext3 file system has failed, although it is a log file system with logging function, but in the Ossim system, Ext3 file is not in a high-load read-write mode, this accidental power-down, for Ossim is not only the loss of data so simple, it is possible that the file system internal structure has been inconsistent, resulting in file system failure, the results of the system restarts, it stopped in the interface as shown.
