[ceph-users] Problems with multipart RGW uploads.

2016-12-09 Thread Martin Bureau 
Hello,


I am looking for help with a problem we have with our Jewel (10.2.4-1-g5d3c76c) 
cluster. Some files (which show up in the bucket listing) cannot be downloaded 
and return HTTP 404 and "ERROR: got unexpected error when trying to read 
object: -2" in the rgw log.


Regards,

Martin

[ceph-users] Can't download some files from RGW

2016-11-24 Thread Martin Bureau 

Hello,

I have some files that have been uploaded to a Ceph Jewel (10.2.2) 
cluster but can't be downloaded afterwards. HEAD on the file is 
successful but GET returns 404.


Here is the output from object stat for one of these files :

# radosgw-admin object stat --bucket=sam-storage-mtl-8m-00 
--object=data/000/053/264/53264382

[ceph-users] Same pg scrubbed over and over (Jewel)

Hello,


I noticed that the same pg gets scrubbed repeatedly on our new Jewel cluster:

[ceph-users] Read performance in VMs

2015-10-05 Thread Martin Bureau 
Hello,

Is there a way to improve sequentials reads in a VM ? My understanding
is that a read will be served from a single osd at a time, so it can't
be faster than the drive that osd in running on. Is that correct ? Is
there any ways to improve this ?

Thanks for any answers,
Martin
