Hi Jeff, its nice to provoke a response out of you...when are you coming to a meeting? :-) On Wed, Apr 29, 2015 at 09:40:09AM -0400, Jeff Moyer wrote:
I wouldn't trust my data to btrfs, especially if you're using anything other than the default mkfs and mount options. But don't take my word for it, have a look through the btrfs mailing list archives[1].
I see what you mean. People are still asking questions "how do I fix this broken fs?" and being told to upgrade to linux kernel 4.0.
I have no experience with zfs on linux, but I've heard that data checksums have a signficant performance impact. I don't have any data on that, so you should probably do your own benchmarking to verify things perform well enough for your workload.
If I were you, I'd use xfs.
I don't like XFS because it can't be shrunk in place. Too many times I've needed to shrink one LV to make space for another LV.
