similar to: [ufs-discuss] statvfs change

An issue was found with the netBeans installer where the installation was failing on a large ZFS filesystem. This resulted in CR 6560644 (zfs statvfs f_frsize needs work). The issue is that large filesystems can cause EOVERFLOW on statvfs() calls. This behavior is documented in the statvfs(2) man page, but I think we can do better. The problem was initially reported against ZFS, and my first fix

common/mlutils: Unix_utils.StatVFS.statvfs: This commit implements a full-featured binding for the statvfs(3) function. We then use this to reimplement the daemon statvfs API in OCaml. Note that the Gnulib fallback is fixed in this commit. It previously referenced non-existent field names in the fs_usage struct. --- common/mlutils/unix_utils-c.c | 138 ++++++++++++++++++++++++++++---

hi guys,   happy new year!!!  I encountered  a problem when we used virt-df command to display my guest disks useage. the virt-df command from pkg libguestfs-tools-c-1.36.3-6.el7_4.3.x86_64,version is  virt-df --version : virt-df 1.36.3rhel=7,release=6.el7_4.3,libvirt the output in guest with the method referred in http://libguestfs.org/virt-df.1.html#STATVFS NUMBERS is:

I'd like to propose the following extensions to the SFTP protocol. - statvfs operation - atomic rename (just plain POSIX rename() without the existence check) These are the most requested features in SSHFS, which need support in sftp-server too. They could be added to the current protocol with the SSH_FXP_EXTENDED message type. Here's a patch implementing the statvfs operation. It

Thanks for the report.? According to my reading, this use of "mv" is ok and the renameat2() call which the invocation of "mv" leads to is also ok and allowed by POSIX in this context. It could only fail with EEXIST if the target directory (path/pkg) was not empty. So far I've not been able to reproduce but we could fall back to copy like on Windows. Best Tomas On

Hi list, We have an ancient hack that fuse not just passes on the statvfs data it's getting from the storage, but tweaks it by setting f_bsize / f_frsize to values of its own preference. [1] The supposed advantage is that f_bsize serves as a hint to applications for the preferred io size. (And regarding f_frsize -- in Linux it's a historical workaround for certain bugs in userspace[2]

The latest version that Western Digital has shipped with the My cloud devices accesses the disk about twice a minute. The access to /dev/sda2 is causing the system to keep the disk from going into standby mode. I don't understand the call to quotactl every minute when no one is trying to access the share. An strace of one of the processes shows the following: poll([{fd=13,

This is needed to be able to support statfs operation on an SSH filesystem (http://fuse.sourceforge.net/sshfs.html). It uses and sends only those fields of struct statfs which are common with struct statvfs as defined by POSIX, and which are shared among most UNIX-like systems. The SSH_FXP_EXTENDED message type is used, so this change is backward compatible and conforms to the protocol

And while we are at it, can you please comment on these patches as well, originally submitted around one year ago. Oh, and I think we can agree, that the secsh-filexfer standardization is dead, so there's not much point in trying to support newer protocol versions, which don't have statfs anyway. Thanks, Miklos ----- This is needed to be able to support statfs operation on an SSH

[Jim, as coreutils developer, this might interest you] In libguestfs we run some quite detailed checks of the output of the statvfs system call for our tool "virt-df". I noticed that the output of virt-df changed slightly. Narrowing it down, the difference only happens between: Fedora kernel 3.2.0-0.rc0.git4.1.fc17 (3rd Nov) Fedora kernel 3.2.0-0.rc1.git2.1.fc17 (11th Nov) With
