What do you think about ext4 filesystem in the production enviroment ? We are very close to launching our project that will use tens of millions quite often updated not very big files and we need to decide which FS to use.
For a while our considerations about other linux FS are:
- Ext3 is rock stable, but not very well suited for handling millions small files
- XFS looks very nice, probably we'll use it
- ReiserFS ... well...vague future, who will end up fixing bugs ?
