Re: [ceph-users] data loss when flattening a cloned image on giant

really sorry for the bad format, I will put it here again.   I found data lost when flattening a cloned image on giant(0.87.2). The problem can be easily reproduced by runing the following script:     #!/bin/bash     ceph osd pool create wuxingyi 1 1     rbd create --image-format 2 wuxingyi/disk1.

Re: [ceph-users] Ceph Write process

Thanks Loris, So after client receiving ACK, if client makes a read request to this object immediately , does it have to wait for object written to file store, or read directly from journal? 2016-01-25 17:12 GMT+07:00 Loris Cuoghi : > > Le 25/01/2016 11:04, Sam Huracan a écrit : > > Hi Cephers, >

Re: [ceph-users] ceph fuse closing stale session while still operable

Hi Greg, thank you for your suggestions. Just let me clearify one little thing: It starts working as soon as i load the kernel rbd/ceph module. I do not need to establish any connection based on that modules to the ceph cluster. Just loading the kernel modules with modprobe (before mounting wi

[ceph-users] KVstore vs filestore

Hi, I'm questionning myself about leveldb-based KVstore Is it a full drop-in for filestore ? I mean, can I store multiple TB in a levelDB OSD ? Is there any restriction for leveldb ? (object size etc) Is leveldb-based KVstore considered by the ceph community as "stable" ? Can I mix filestore an

Hey cephers, We’re in the midst of a pivot on metrics.ceph.com that will include several new data sources and a new interactive front-end. If you would like to play with the unfinished prototype and provide feedback, now is the time! http://s.bitergia.com/db-ceph-git There is still some work to

Re: [ceph-users] data loss when flattening a cloned image on giant

Interesting find. This is an interesting edge case interaction between snapshot, flatten, and rollback. I believe this was unintentionally fixed by the deep-flatten feature added to infernalis. Probably the simplest fix for giant would be to restore the parent image link during the rollback (

[ceph-users] How-to doc: hosting a static website on radosgw

Hi everyone, we recently worked a bit on running a full static website just on radosgw (akin to http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteHosting.html), and didn't find a good how-to writeup out there. So we did a bit of fiddling with radosgw and HAproxy, and wrote one: https://www.has

Re: [ceph-users] upgrading 0.94.5 to 9.2.0 notes

I see the same list of issues, particularly where ceph.target doesn't function until i 'enable' the daemons individually. It would be nice if the package enabled the daemons when it is installed, so that ceph.target works. Perhaps this could be fixed for Jewel? -Ben On Sat, Nov 21, 2015 at 12:22

Re: [ceph-users] confusing release notes

All ceph releases are stable, but they are stable LTS for firefly,hammer,jewel,... So with LTS releases, you'll have more updates on the longterm. with infernalis for example, you can expect 2 or 3 point releases maximum, then you'll need to upgrade to jewel if you want to have new updates. (I
