[05:03] <th3s3_3y3s> infinity and apw do you want to be debugs?
[11:28] <Ben64> so when do we get new kernels without rebooting?
[13:47] <alexbligh1> Does the ubuntu kernel in any way change the default mount options for ext4? IE barriers=1, data=ordered?
[13:50] <apw> alexbligh1, not using fstab you mean?  not that i know of, but not something i have wanted to do
[13:51] <alexbligh1> apw, I mean fstab is specifying nothing fancy, yet I'm seeing a (postgres) crash behaviour that is similar to what I'd expect if barriers=0. I'm wondering if the (old) hdd doesn't support barriers (though the telltale message isn't in the log) or whether there's an 'optimisation' in the kernel (cough). (f)stab in the dark.
[13:52] <apw> alexbligh1, not that i am aware of, no ... hrm
[13:53] <alexbligh1> apw, dim recollection of different distros using different default mount options but I think that was for ext3 a hundred years ago.
[13:56] <apw> alexbligh1, yep i'd agree with that feeling
[13:58] <alexbligh1> ape, thx anyway
[13:58] <jtaylor> hi, you probably also want 808f80b46 in addition to 46e971cdcd (upstream 005efedf2c) in 3.19-queue
[13:59] <jtaylor> (btrfs read corruption issues)
[14:00] <apw> henrix, ^
[14:00] <apw> kamal, ^
[14:04] <henrix> jtaylor: ack, thanks.  seems to be urgent, so we'll probably squash it into the stable kernels under review
[14:05] <jtaylor> not super urgent as you need to compress and deduplicate, but as you have one of the patches you might as well have both
[14:07] <henrix> jtaylor: yeah, since that extra commit is also tagged for stable, it will get into stable kernels (in fact, it's already in the 3.16 -queue!)
[14:07] <jtaylor> its already in 4.2 stable
[15:16] <kamal> jtaylor, yes, thanks for the heads-up.  I'll apply this to 3.19-stable and 3.13-stable today and so it'll release with the other btrfs read corruption fix
[15:16] <kamal> 808f80b Btrfs: update fix for read corruption of compressed and shared extents
[15:16] <kamal> henrix, fyi ^
[15:17] <henrix> kamal: yep, i was going to do exactly the same for 3.16 ;)
