Hi all,
Does anyone have any recommendations for good tools to perform
file-system/tree backups and restores to/from a RGW object store (Swift or
S3 APIs)? Happy to hear about both FOSS and commercial options please.
I'm interested in:

Success! There was an issue related to my operating system install procedure
that was causing the journals to become corrupt, but it was not caused by ceph!
That bug fixed; now the procedure on shutdown in this thread has been verified
to work as expected. Thanks for all the help.

Over the weekend, two inconsistent PG’s popped up in my cluster. This being
after having scrubs disabled for close to 6 weeks after a very long rebalance
after adding 33% more OSD’s, an OSD failing, increasing PG’s, etc.
It appears we came out the other end with 2 inconsistent PG’s and I’m tryin

Hello,
So, I need maybe some advices : 1 week ago (last 19 feb), I upgraded my
stable Ceph Jewel from 10.2.3 to 10.2.5 (YES, It was maybe a bad idea).
I never had problem with Ceph 10.2.3 since last upgrade, last 23 September.
So since my upgrade (10.2.5), every 2 days, the first OSD server t

Ok,

But if the guest VM on the same Hypervisor try to using the image, what

Are these safe tools? (aka: safely exit with error instead of try the

In that case, the trim/discard requests would need to come directly
from the guest virtual machines to avoid damaging the filesystems. We
do have a backlog feature ticket [1] to allow an administrator to
transparently sparsify a in-use image via the rbd CLI, but no work has
been started on it yet.
Hi Ahsley,
The rule you indicated, with “step choose indep 0 type osd” should select 13
different OSDs but not necessary on 13 different servers. So you should be able
to test that on say 4 servers if you have ~4 OSDs per server.
To split the selected OSDs across 4 hosts, I think you would do s

I need some further info, because I'm really worried about ruin my data.
On this pool I have only XEN virtual disks.
Did I have to run the command directly on the "pool" or on the "virtual

I guess that I have to run it on the pool.

Hi all,
yesterday we encountered a problem within our ceph cluster. After a long day we
were able to fix it, but we are very unsatisfied with the fix and assume that
it is also only temporary. Any hint or help is very appreciated.
