In the case of:

import os

fd = os.open("/mnt/mycephfs/enc1/file1", os.O_CREAT)
os.close(fd)
fd = os.open("/mnt/kclient/enc1/file1", os.O_WRONLY)
os.close(fd)

os.truncate("/mnt/mycephfs/enc1/file1", 1024)
print(os.stat("/mnt/mycephfs/enc1/file1"))
os.truncate("/mnt/kclient/enc1/file1", 900)
print(os.stat("/mnt/mycephfs/enc1/file1"))

os.remove("/mnt/mycephfs/enc1/file1")

st_size in both prints will be 1024
