Re: Luminous 12.2.1 - RadosGW Multisite doesnt replicate multipart uploads

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Multipart is a client side setting when uploading.  Multisite in and of itself is a client and it doesn't use multipart (at least not by default).  I have a Jewel RGW Multisite cluster and one site has the object as multi-part while the second site just has it as a single object.  I had to change from looking at the objects in the pool for monitoring to looking at an ls of the buckets to see if they were in sync.

I don't know if multisite has the option to match if an object is multipart between sites, but it definitely doesn't seem to be the default behavior.

Hi all,

i just setup multisite replication according to the docs from http://docs.ceph.com/docs/master/radosgw/multisite/ and everything works except that if a client uploads via multipart the files dont get replicated.

If i in one zone rename a file that was uploaded via multipart it gets replicated, but not if i left it untouched. Any ideas why? I remember there was a similar bug with jewel a while back.

On the slave node i also permanently get this error (unrelated to the replication) in the radosgw log:

 meta sync: ERROR: failed to read mdlog info with (2) No such file or directory

we didnt run radosgw before the luminous upgrade of our clusters.

after a finished multipart upload which is only visible at one zone "radosgw-admin sync status" just shows that metadata and data is caught up with the source.
