I've read through the archives and it looks like people are using ext3 with software RAID with at least some success. I just want to confirm that it works properly. If I convert my md RAID 0 to ext3, should I expect A) A fast journalled filesystem, or B) Wailing and gnashing of teeth My RAID currently does not use persistant superblocks, because I created it many moons ago under the old raidtools. Should I convert it to the new style before making it ext3, or is is not relevant? Regards, Jeffrey Baker
Thumbs up on ext3 but I am running with the latest raid version on Linx 2.4.8. I'm using it on 3 different systems now on RAID1 and RAID5. I/O is a little slower but the recovery time from a crash is a LOT less so it's worth it to me (and I'm a performance freak). I know you can "upgrade" your raid (i.e "mkraid --upgrade) but I'm not sure about "upgrading" to persistent superblocks. ----- Original Message ----- From: "Jeffrey W.

New raid is theoretically better, but if old it working for you, stick with it. To convert to new style with superblocks, you would need to backup all your data, remake the array and filesystem, and then restore.
