Re: RGW/swift segments

[Peter Eisch <peter.eisch@xxxxxxxxxxxxxxx>]

I’ve verified this is still broken on Nautilus (14.2.4).  The code for deleting a swift object split into segments is correct.  I’m now trying to follow the object expirer code.  It seems it reads the metadata for the lead object (0-bytes in length) and expires that correctly but never understands to look for its associated segments in the metadata.  It could be because these are stored in a different bucket – I’m not sure.  Once the lead object is deleted, the metadata is removed and all the segments are then orphaned.

 

Is anyone here familiar with the RGWObjectExpirer code who I could confer?

I should have noted this is with Luminous 12.2.12 and consistent with swiftclient versions from 3.0.0 to 3.8.1, which may not be relevant.  With a proper nod I can open a ticket for this – just want to make sure it’s not a config issue.

 

[client.rgw.cephrgw-s01]

  host = cephrgw-s01

  keyring = /etc/ceph/ceph.client.rgw.cephrgw-s01

  rgw_zone = <redacted>

  rgw zonegroup = us

  rgw realm = <redacted>

  rgw dns name = rgw-s00.<redacted>

  rgw keystone admin project = admin

  rgw keystone admin user = admin

  rgw keystone api version = 3

  rgw keystone url = "">

  rgw thread pool size = 4096

  rgw keystone revocation interval = 300

All tips accepted…

Subject: RGW/swift segments

 

 

Hi,

 

When uploading to RGW via swift I can set an expiration time.  The files being uploaded are large.  We segment them using the swift upload ‘-S’ arg.  This results in a 0-byte file in the bucket and all the data frags landing in a *_segments bucket.

 

When the expiration passes the 0-byte file is delete but all the segments remain.  Am I misconfigured or is this a bug where it won’t expire the actual data?  Shouldn’t RGW set the expiration on the uploaded segments too if they’re managed separately?

 

Thanks,

 

peter
