I'm more than a bit turned off after experiencing data loss with ext4 :(

If you care about the data you're saving you'll use ext3 :)

What brought about the data loss?

I've used ext4 since it came out and have yet to have issues with it. My database is 80GB on a Plextor SSD, backed onto an WD VelicoRaptor HDD online, then offline to an ordinary Seagate HHD, and finally to an HDD on a netbook. Have an APC UPS for online data protection.

There was an issue with LibreOffice documents disappearing and being unrecoverable with ext4. I don't know if that has been addressed or not.

It's well documented:

I like truly stable stuff so I use ext3 :)

"Apparently, the data corruption bug was hard to track down as it only manifests itself if a system is rebooted twice in a relatively short period of time."

Thanks for the links... hope it gets fixed one of these days, sooner than later. <smile>
