From: Wismerhill <philipp.plato <at> mailbox.org> To: bug-coreutils <at> gnu.org Subject: unwanted behavior in the combination of an scenario regarding btrfs, ssh, borg, and 'df' from the core utils Date: Fri, 24 Jan 2020 20:50:22 +0100
Hi, My Name is Phil, i found an unwanted behavior in the combination of an scenario regarding btrfs, ssh, borg, and 'df' from the core utils. Scenario: I want to setup a home server (OpenSuse 15.1 - with newer kernel 5.4.13-9). I have 4 disks and want to use btrfs for a raid config (raid 5 for data; raid 1 for metadata) resulting in 6,5 TB free space; NO Snapshots enabled/used; NO Snapper). The plan is that 3 clients (clients are same config like the server (OpenSuse and kernel) back up their home folder via borg over ssh on the raid of the server. (about 650 GB and 500000 files each client) What happend: When i start a borg backup via ssh, it interrupt with the following error message "Insufficient free space to complete transaction (required: 116.30 MB, available: 0 B) FILENAME" I did try some stuff, and at the end it looks like borg finishes withe this error in because 'df' reports a wrong space calculation to ssh and ssh tells borg to stop in because of that. - the problem only apears in the combination of btrfs and a Raid 5 or 6 for data on the target. - on a special point when i move larger amount of data (some 100 of GBs). Solution / Request for help: 'df' can determin the FS-type, if df for example recognize the filesystem it was asked for is btrfs, df 'ask' the btrfs-utils (btrfs filesystem usage) for help/delegate the request (asumed that on a system where a btrfs filesystem is, the coresponding tools are also installed. I don´t want to change the filesystem since btrfs-rescue convinced me. But searching for answers i found out that many Admins didn´t use btrfs in Raid 56 mode in because of fear of the writehole bug. This writehole bug is not that dangerous if i have the metadata mirrored in raid 1. And Borg is a cool solution with its deduplicating capabilities. I use btrfs on every machine and ssh (sftp) are my only used protokoll for homenet dataexchange. I hope you can provide a patch for it, since btrfs developed to a grade where stabilitie and its features are truley an alternativ for ext4, and i think its only a matter of time it will become the main filesystem for linux. I was also considerating to do it with aliases on the shell, but the script have to be bigger to cover all possible Options and their combinations. Also I´m not shure if that solution will not open other failures since df is kind of historical and used as core in many ways for a lot of programms e.g. ssh :-) kind regards Philipp Plato

What's wrong about the space calculation?
Please give the 'df' command that you ran, its faulty output, and also
the output of 'strace' applied to the 'df' command that you ran. For
example, on my machine, 'strace df' outputs the line:
statfs("/tmp", {f_type=TMPFS_MAGIC, f_bsize=4096, f_blocks=1018122,
f_bfree=1007348, f_bavail=1007348, f_files=1018122, f_ffree=1018073,
f_fsid={val=[0, 0]}, f_namelen=255, f_frsize=4096,
f_flags=ST_VALID|ST_NOSUID|ST_NODEV}) = 0
and those are the numbers that 'df' uses to calculate what it should
output. If those numbers are wrong, df's output will be wrong but it's
not df's fault - it's the kernel or btrfs or whatever. If those numbers
are right but df's output is wrong, then df is at fault.

[cc'ing 39273 <at> debbugs.gnu.org; please keep them in the loop.]
In response to the email quoted below, the key issue seems to be here:
> statfs("/", {f_type=BTRFS_SUPER_MAGIC, f_bsize=4096,
> f_blocks=100657920, f_bfree=86044517, f_bavail=0, f_files=0, f_ffree=0,
> f_fsid={val=[517186897, 2414566026]}, f_namelen=255, f_frsize=4096,
> f_flags=ST_VALID|ST_RELATIME}) = 0
That is, the statfs system call says that "/" has no blocks available.
To fix this, you'll need to see why the kernel (presumably in its btrfs
filesystem code) is mistakenly saying that f_bavail=0. This stuff is
inside the kernel so df and coreutils are not the problem here.
You might ask the Linux-BTRFS mailing list about this. It appears to be
related to a known issue in their code; see:
