Subject: Sparse files and Linux
To: "[email protected]" <[email protected]>,
samba-technical <[email protected]>
Tried a simple test to see about sparse file creation to Samba from Linux.
Results:
Local (ext4): both file1 and file2 are sparse
Remote over cifs to samba (unix extensions): file1 not sparse, file2 is sparse
Remote over cifs to samba (unix extensions disabled): file1 and file2 not sparse
Remove over smb3 to samba: file1 and file2 not sparse
Presumably can fix it with explicit set sparse.
#!/usr/bin/env python
#
# Test sparse file support
import os, struct, stat, sys
file1 = open("test_file1", "w")
file1.seek(200000000L)
file1.write("Hello")
file1.close
file2 = open("test_file2", "w")
file2.truncate(205000000L)
file2.write("Hello")
file2.close
