[ceph-users] Peering algorithm questions

Hey! I'm trying to understand the peering algorithm based on [1] and [2]. There are things that aren't really clear or I'm not entirely sure if I understood them correctly, so I'd like to ask some clarification on the points below: 1, Is it right, that the primary writes the operations to the PG

[ceph-users] RGW: Can't download a big file

I'm having some issues downloading a big file (60G+). After some investigation it seems to be very similar to http://lists.ceph.com/pipermail/ceph-users-ceph.com/2015-May/001272.html, however I'm currently running Hammer 0.94.3. However the files were uploaded when the cluster was running Firefly

Re: [ceph-users] Issue with journal on another drive

Jiri, if you colocate more Journals on 1 SSD (we do...), make sure to understand the following: - if SSD dies, all OSDs that had their journals on it, are lost... - the more journals you put on single SSD (1 journal being 1 partition), the worse performance, since total SSD performance is not

Re: [ceph-users] CephFS file to rados object mapping

The formula for objects in a file is .. So you'll have noticed they all look something like 12345.0001, 12345.0002, 12345.0003, ... So if you've got a particular inode and file size, you can generate a list of all the possible objects in it. To find the object->OSD mapping you'd need

Re: [ceph-users] Issue with journal on another drive

Hi Lionel. Thank you for your reply. In this case I am considering to create separate partitions for each disk on the SSD drive. Would be good to know what is the performance difference, because creating partitions is kind of waste of space. One more question, is it a good idea to move

Re: [ceph-users] CephFS Attributes Question Marks

Ah, this is a nice clear log! I've described the bug here: http://tracker.ceph.com/issues/13271 In the short term, you may be able to mitigate this by increasing client_cache_size (on the client) if your RAM allows it. John On Tue, Sep 29, 2015 at 12:58 AM, Scottix wrote:

Thanks, that makes a lot of sense. One more question about checksumming objects in rados. Our cluster uses two copies per object, and I have some where the checkums mismatch between the two copies (that deep scrub warns about). Does ceph store an authoritative checksum of what the block should

Re: [ceph-users] Simultaneous CEPH OSD crashes

It's an EIO. The osd got an EIO from the underlying fs. That's what causes those asserts. You probably want to redirect to the relevant fs maling list. -Sam On Tue, Sep 29, 2015 at 7:42 AM, Lionel Bouton wrote: > Le 27/09/2015 10:25, Lionel Bouton a écrit : >>

I think I got over 10% improvement when I changed from cooked journal file on btrfs based system SSD to a raw partition on the system SSD. The cluster I've been testing with is all consumer grade stuff running on top of AMD piledriver and kaveri based mobo's with the on-board SATA. My SSDs
