How to discern, if a directory is NFS-mounted from Ansible?

你说的曾经没有我的故事 提交于 2020-01-14 14:57:07
问题 I need to set up an application directory for a "hairy" app. Depending on the case, the directory may be local to each server participating, or shared among several servers via NFS. So, I need to be able to detect, whether the given path is local or NFS-accessed and skip some of the tasks in the latter case. What's the best way to detect this in an Ansible role? I tried using the stat module, but device_type seems to be set to 0 in all cases, NFS or local (XFS). On Linux I could invoke stat

Binutils stat illegal option -c

会有一股神秘感。 提交于 2020-01-13 09:44:12
问题 I use stat two times in my script once to find the file files permissions and once to find the size of the file. `stat -c %A "$directory/$file"` `stat -c %s "$directory/$file"` I am using OSX 10.7 and directory and file are variable of the current directory I am in and the file. 回答1: Darwin stat uses an -f argument, rather than -c , as it is a GNU extension. You should download the gnu binutils, either from homebrew, from macports or from fink, and then use gstat instead of stat . If you don

On Linux, is access() faster than stat()?

笑着哭i 提交于 2020-01-13 08:12:11
问题 I would have assumed that access() was just a wrapper around stat(), but I've been googling around and have found some anecdotes about replacing stat calls with 'cheaper' access calls. Assuming you are only interested in checking if a file exists, is access faster? Does it completely vary by filesystem? 回答1: Theory I doubt that. In lower layers of kernel there is no much difference between access() and stat() calls both are performing lookup operation : they map file name to an entry in

What is lstat() alternative in windows?

回眸只為那壹抹淺笑 提交于 2020-01-12 07:57:05
问题 In linux, when stat() is used with broken link files, it fails with -1 . So I used lstat() which succeeded. For the same case in windows, _stat() fails with broken shortcuts, but there is no _lstat() in windows. Please help to find the alternative for lstat() in windows. 回答1: GetFileAttributes or GetFileAttributesEx probably (if I understood stat and lstat right). Quoting from the docs: Symbolic link behavior—If the path points to a symbolic link, the function returns attributes for the
