Re: [ceph-users] RBD features(kernel client) with kernel version

I have to admit that it's probably buried deep within the backlog [1]. Immediate term alternative solutions to presenting a RBD-backed block device that support journaling is available via rbd-nbd (creates /dev/nbdX devices) and also via LIO's tcmu-runner and a loopback target (creates /dev/sdX

Re: [ceph-users] inconsistent pg will not repair

The following is based on the discussion in: http://tracker.ceph.com/issues/21388 -- There is a particular scenario which if identified can be repaired manually. In this case the automatic repair rejects all copies because none match the selected_object_info thus setting

[ceph-users] osd max scrubs not honored?

With “osd max scrubs” set to 1 in ceph.conf, which I believe is also the default, at almost all times, there are 2-3 deep scrubs running. 3 simultaneous deep scrubs is enough to cause a constant stream of: mon.ceph1 [WRN] Health check update: 69 slow requests are blocked > 32 sec (REQUEST_SLOW)

Re: [ceph-users] Access to rbd with a user key

Keep in mind you can also do prefix-based cephx with caps. That was set up so you can give a key ring access to specific RBD images (although you can’t do live updates on what the client can access without making him reconnect). On Tue, Sep 26, 2017 at 7:44 AM Jason Dillaman

Re: [ceph-users] osd crashes with large object size (>10GB) in luminos Rados

Nick, Thanks, I will look into the latest bareos version. They did mention libradosstriper on github. There is another question. On jewel I have 25GB size objects. Once I upgrade to luminous those objects will be "out of bounds". 1. Will OSD start and Will I be able to read them? 2. Will they

You can update the server with the mapped rbd and shouldn't see as much as a blip on your VMs. On Tue, Sep 26, 2017, 3:32 AM Götz Reinicke wrote: > Hi Thanks David & David, > > we don’t use the fuse code. And may be I was a bit unclear, but your > feedback clears

[ceph-users] osd crashes with large object size (>10GB) in luminos Rados

Hello, We successfully use rados to store backup volumes in jewel version of CEPH. Typical volume size is 25-50GB. Backup software (bareos) use Rados objects as backup volumes and it works fine. Recently we tried luminous for the same purpose. In luminous developers reduced osd_max_object_size

Hi, I noticed the ceph version still gives "rc" although we are using the latest Ceph packages: 12.2.0-1xenial (https://download.ceph.com/debian-luminous xenial/main amd64 Packages): ceph daemon mon.mon5 version {"version":"12.2.0","release":"luminous","release_type":"rc"} Why is this important

Hi Thanks David & David, we don’t use the fuse code. And may be I was a bit unclear, but your feedback clears some other aspects in that context. I did an update already on our OSD/MONs while a NFS Fileserver still had a rbd connected and was exporting files (Virtual disks for XEN server)
