Please give me advice about the following problem. A few days ago, I lost some of oracle DB data on my server. My server was running Oracle DB and HA(high availability) server for web service. The filesystem was ext3, version 0.5b. Suddenly HA server made error and rebooted alternately. So I stoped HA server and looked over mounted filesystem. When I thought the filesystem was destroyed, I ran the command, fschk.ext3. But it didn't work properly. Finally, I lost some of data. My question is "Is ext3 filesystem stable?" When I asked our HA server vender what the reason was, they said ext3 filesystem occured that problem. I don't think HA server is reliable, but worry about the stability of ext3. Thanks,

My experience is that 0.7a is quite stable for 2.2 kernels. I'm personally, using 0.9.5 on the 2.4.7 kernel, and it works quite well. On the other hand, 2.4 still has a number of VM issues. By the way, you didn't run fsck.ext3 on a mounted filesystem, did you? That's a really bad idea... - Ted

The filesystem was ext3, version 0.5b.0.5b is truly ancient, and I expect that you're probably running an equally old e2fsprogs if that's the case. There have been several possible recovery bugs fixed since then. The most important one was fixed in 0.0.7a. You really should upgrade to ext3-0.0.7a and e2fsprogs-1.22 if you are still on 0.5b and want to stay with a 2.2 kernel. Right now, though, the 2.4 ext3 code has by far the most testing and has many performance improvements over the 2.2 version. 2.2 is in critical-bugfix-only mode right now. Cheers, Stephen
