Original GitHub issue: https://github.com/s3fs-fuse/s3fs-fuse/issues/497

[CRT] s3fs.cpp:set_s3fs_log_level(253): change debug level from [CRT] to [INF]
[INF] s3fs.cpp:set_moutpoint_attribute(4151): PROC(uid=0, gid=0) - MountPoint(uid=0, gid=0, mode=40755)
s3fs: There is no enough disk space for used as cache(or temporary) directory by s3fs.

I am getting the error although I have enough disk space. S3testdemo1 has around 300gb free space and my /tmp/nav folder has 50g of free space.. what should be the work around?

Can you add some logging to FdManager::IsSafeDiskSpace so we can diagnose this further?

@vgadhadaran I'm sorry for my late reply,
And Thanks @andrewgaul

s3fs checks free disk space at starting by using statvfs function.
So you do not specify use_cache option, s3fs checks free disk space by "/tmp/" path.
It seems that this result is false, thus statvfs result is under 10MB.

Could you add the debugging codes in FdManager::GetFreeDiskSpace() in fdcache.cpp?
(or in FdManager::IsSafeDiskSpace() function, andrewgaul said.)

Thanks in advance for your help.

s3fs: There is no enough disk space for used as cache(or temporary) directory by s3fs.

I had plenty of disk space. In this case, /tmp/s3fs_cache didn't exist. When I created it, the mount worked fine.

Even though I didnt set use_cache option, where does it points to the temp directory , as it prompts there is no enough disk space?
Adding this line in fdcache.cpp will be sufficient

FdManager::InitEnsureFreeDiskSpace();
if(!FdManager::IsSafeDiskSpace(NULL, S3fsCurl::GetMultipartSize())){
S3FS_PRN_EXIT("There is no enough disk space for used as cache(or temporary) directory by s3fs.");
exit(EXIT_FAILURE);
}

Is there any command parameters that I can pass on with s3fs command for diskspace?

when does not specify use_cache option, default path is /tmp
we changed codes about checking free disk space recently, #557.
so please try to use latest version on mster branch.

I am sorry to have trouble, if you can please retry to use latest codes.
Thanks in advance for your assistance.
