From d1ccc4e400728d90f2ef7904661f53deb7199123 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Wed, 8 May 2013 08:54:11 -0400 Subject: gluster: add fallocate fop support Implement support for the fallocate file operation. fallocate allocates blocks for a particular inode such that future writes to the associated region of the file are guaranteed not to fail with ENOSPC. This patch adds fallocate support to the following areas: - libglusterfs - mount/fuse - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi BUG: 949242 Change-Id: Ice8e61351f9d6115c5df68768bc844abbf0ce8bd Signed-off-by: Brian Foster Reviewed-on: http://review.gluster.org/4969 Tested-by: Gluster Build System Reviewed-by: Anand Avati --- api/examples/gfapi.py | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'api/examples') diff --git a/api/examples/gfapi.py b/api/examples/gfapi.py index 7d7a5bab1..8dfe2791d 100755 --- a/api/examples/gfapi.py +++ b/api/examples/gfapi.py @@ -98,6 +98,9 @@ class File(object): def write (self, data, flags=0): return api.glfs_write(self.fd,data,len(data),flags) + def fallocate (self, mode, offset, len): + return api.glfs_fallocate(self.fd, mode, offset, len) + class Dir(object): def __init__ (self, fd): @@ -349,6 +352,16 @@ if __name__ == "__main__": return False, "wrong listxattr value %s" % repr(xattrs) return True, "listxattr worked" + def test_fallocate (vol, path, data): + mypath = path + ".io" + fd = vol.creat(mypath,os.O_WRONLY|os.O_EXCL,0644) + if not fd: + return False, "creat error" + rc = fd.fallocate(0, 0, 1024) + if rc != 0: + return False, "fallocate error" + return True, "fallocate worked" + test_list = ( test_create_write, test_open_read, @@ -363,6 +376,7 @@ if __name__ == "__main__": test_setxattr, test_getxattr, test_listxattr, + test_fallocate, ) ok_to_fail = ( -- cgit
