Hello, (this is a recap of yesterday''s discussion on BTRFS IRC, also to save relevant pastes before pastebins expire) I have my /home on btrfs; a cronjob makes one snapshot every 30 minutes; these snapshots are kept for 24-48 hours, then deleted in batches. This is a 16K Leaf/Node BTRFS on top of mdadm RAID1. As system uptime approached 2 weeks, I started noticing that the free space

I''ve been working on running down intermittent ENOSPC issues. I can only seem to replicate ENOSPC errors when running zlib compression. However, I have been seeing similar ENOSPC errors to a lesser extent when playing with the LZ4HC patches. I apologize for not following up on this sooner, but I had drifted away from using zlib, and didn''t notice there was still an issue. My

We need an smb_mb() before waitqueue_active to avoid missing wakeups. Before Mitch was hitting a deadlock between the ordered flushers and the transaction commit because the ordered flushers were waiting for more refs and were never woken up, so those smp_mb()''s are the most important. Everything else I added for correctness sake and to avoid getting bitten by this again somewhere else.

I''m running into a problem with the btrfs-cleaner thread becoming blocked on xfstests 068. The test locks up indefinitely without completing (normally it finished in about 45 seconds on my test box). I''ve replicated the issue on 3.10.0_rc5 and the for-linus branch of 3.9.0. I ran a git bisect on the 3.9.0 for-linus branch, and tracked my issue to the following commit: commit

I am currently looking at a bug report[1] which is happening when a Xen PVM guest with multiple VCPUs is running a high IO database load (a test script is available in the bug report). In experimenting it seems that this happens (or is getting more likely) when the number of VCPUs is 8 or higher (though I have not tried 6, only 2 and 4), having autogroup enabled seems to make it more likely, too

I am back at this, again, trying to get my linux PXE server back up and running. I have the x86_pc (pxelinux.0) boots fine. I can boot Ubuntu Gnome 16.04 to teh setup screen. Every time I attempt to boot the same nfs from a computer which can boot via efi (x64_efi), I get a failed transfer. This is with 6.04_pre I grabbed well over a year ago. What happens is I get a TFT transport error. This is
