system read only error(help)

lost world · 02-13-2006, 03:19 AM

my system is slackware 10.1(2.6.11kernel)
filesystem is ext3.
The after system uses one period of time, appears the operating system read-only breakdown.When I use some systems order,for exampel,vi/dmesg/
the system show : bash: Read-only file system pr
bash: /bin/dmesg: Input/output error

then system read only,can not write. after I re- starts system, the question solved. But one period of time, the breakdown re- appeared.
now,i replace the hard disk, and this breakdown appears on the different machine,so i think may remove the hardware reason.But i don't know what reason cause this kind of breakdown.
Who can tell me what reason ,thank you very much!!

Ext3fs has an option to change the behavior of the kernel when errors are detected. One of the options is to remount the partition read-only. Run this as root to see the error-behaviour values:

Code:

fdisk -l|grep Linux$|awk '{print $1}'|while read part; do tune2fs -l $part|egrep -i "(me.nam|err.*behav)"; done

To change it run "tune2fs -e continue device", where device is one of the partitions you found has the wrong error behaviour.
If error-behaviour is not the cause, are there any clues in your system logs?
