Kind of late response, but I strongly agree with Thomas. I've had my share of truncated files after unclean shutdowns (every single time), some kernel modules being among the victims. If you decide to decide to use ext4, then it's almost mandatory to use the 'nodelalloc' mount option, unless you're positive that unclean shutdowns are unlikely in your setup or you don't care about lost data.
Isn't that option auto_da_alloc?
Well, I thought I would close the thread with a follow-up on how it went and what I ultimately went with. I ended up expanding the extended partition to encompass the remainder of the disk. I then created 2 ext4 partitions, a 6 gig for private data that can be mounted for use then unmounted and the remainder as a big data drive. Both are dmraid mirrored partitions. The current mount options are: /dev/mapper/nvidia_ecaejfdip12 /data ext4 defaults 0 1 /dev/mapper/nvidia_ecaejfdip11 /home/david/pvt ext4 defaults 0 1 are you guys saying I should add 'auto_da_alloc' as an option for all ext4 partitions? -- David C.
