Is there any increased potential for data loss with EXT4 filesystem on Linux when using the filesystem with the noauto_da_alloc option (see http://en.wikipedia.org/wiki/Ext4#Delayed_allocation_and_potential_data_loss) . My understanding that Berkeley DB Java edition does not rename database log files as it is described in the referenced article. I understand the different durability options available. My question is whether Berkeley DB would behave - and potentially cause data loss - on EXT4 than on EXT3 with the same durability settings? Thank you.

Neither of the two scenarios described in the wiki article occur with BDB JE so we don't think there is much of a potential problem
