I built a new small server here (commodity hardware, x86-64) and I've installed 32-bit openSUSE 10.2 on it. After the system was installed, configured and up and running, it hung while I was browsing with Firefox. The only thing I could do was to press the reset button on the computer. After the reboot, when I opened Firefox again, I noticed that all my bookmarks were gone. Those bookmarks were imported from my desktop machine a few days after I configured the new server. All file systems on this new server are XFS because I heard good things about it and it generally performs better in database operations compared to other file systems available for Linux. However, I was pretty surprised that when I had to reset the machine because it hung for some reason, all the bookmarks in Firefox were gone, so now I have my doubts about the reliability and data integrity of XFS. My older server, which also runs openSUSE 10.2 (32-bit) but uses Ext3 as file system never had such issues and I had to reset it many times because it was hanging for some reason. Am I right to assume that XFS compared to Ext3 does not do a very good job regarding data integrity? I know a little bit about file systems and I know that most file systems depend on the application to do the right job regarding the way it opens/locks/saves files, but in reality not all applications are written in a safe way to guarantee this. Basically, my two question that I have are: - Why did I lost bookmarks on a machine running XFS while on another one which runs the same OS version but uses Ext3 as file system, it never happened, no matter how many times I had to reset it. - Are there any efforts currently made to increase the data integrity of XFS?
