Ext3 and RAID: silent data killers?Ext3 and RAID: silent data killers?Posted Sep 3, 2009 21:42 UTC (Thu) by Cato (subscriber, #7643)In reply to: Ext3 and RAID: silent data killers? by yohahn Parent article: Ext3 and RAID: silent data killers?
When disks are remounted read-only, there is no message to the end user (at least on Ubuntu) - as a result, one PC where this happened had a read-only root filesystem for weeks until I noticed this from the logs.
Sending notifications of serious system events like this would be very helpful, with a bundle of standard event filters that can easily generate an email or other alert.

You can only remount ro when there are no files open in write mode. And there usually are on /.
