Hello,
Is it possible to use the rados_clone_range() librados API call with an erasure coded pool ? The documentation doesn’t mention it’s not possible. However running the clonedata command from the rados utility (which seems to be calling radios_clone_range()) gives
an error when using a erasuere coded pool :
# rados -p ecpool clonedata file1 file2 --object-locator file1
error cloning ecpool>file1 => ecpool>file2: (95) Operation not supported
Running the same command for a replicated pool works :
# rados -p testpool clonedata file1 file2 --object-locator file1
#
However for this to work both file1 and file2 have to exist which is a bit of a surprise. The file created seems to be called file2<tab>file1 which is also a surprise. Is it not possible to create a new file with as name the given dstname parameter ?
The ceph version is:
ceph version 0.94.1 (e4bfad3a3c51054df7e537a724c8d0bf9be972ff)
Thanks in advance,
Michel
