I will plan to add more logging and other info you have asked for at the
next MDS restart.
As this cluster are being used in production, I have a limited maintenance
window, so unless I don't find a time outside this window you have to wait
until Sunday/Monday to get the logs.
@John, yes I have u
Hello,
We have an issue on one of our clusters. One node with 9 OSD was down
for more than 12 hours. During that time cluster recovered without
problems. When host back to the cluster we got two PGs in incomplete
state. We decided to mark OSDs on this host as out but the two PGs are
still in incom

Already restarted those OSD and then whole cluster (rack by rack,
failure domain is rack in this setup).
We would like to try *ceph-objectstore-tool mark-complete* operation. Is
there any way (other than checking mtime on file and querying PGs) to
determine which replica has most up to date datas?
The librbd API is stable between releases. While new API methods
might be added, the older API methods are kept for backwards
compatibility. For example, qemu-kvm under RHEL 7 is built against a
librbd from Firefly but can function using a librbd from Jewel.

you can use the below cmds:
==
ceph pg dump_stuck stale
ceph pg dump_stuck inactive
ceph pg dump_stuck unclean
===
And the query the PG, which are in unclean or stale state, check for
any issue with a specific OSD.
Thanks

Regarding your original issue, you may want to configure kdump on one of
the machines to get more insight on what is happening when the box
hangs/crashes.
I faced a similar issue when trying 4.4.8 on my Infernalis cluster (box

Hello,
I have a questions regarding the bucket index:
1) As far as know index of a given bucket is the single RADOS object
and it lives in OSD omap. But does it get replicated or not?
2) When trying to copy bucket index pool to some other pool i get the
following error:
$ rados cppool ed-1.rgw.b

All OSDs seems to be ok, they have been restarted, joined cluster after

Hi,
In Ceph cluster, currently we are seeing that COSBench is writing IO to
default pools that are created while configuring rados gw. Can you please
let me know, if there is a way to execute IO (using COSBech) on a specific
pool.
Thanks & Regards,

Hello,
I upgraded a staging ceph cluster from latest Firefly to latest Hammer
last week. Everything went fine overall and I would like to share my
observations so far:
a. every OSD upgrade lasts appr. 3 minutes. I doubt there is any way
to speed this up though
b. rados bench with different block si
Hi All,
Does anybody know if calling a blockdev --flushbufs on a rbd-nbd device
causes the librbd read cache to be invalidated?
I've done a quick test and the invalidate_cache counter doesn't increment
like when you send the invalidate command via the admin socket.
Thanks,
Nick

Hi,
I believe I've stumbled on a bug in Ceph, and I'm currently trying to figure
out if this is a new bug, some behaviour caused by our cluster being in the
midst of a hammer(0.94.6)->jewel(10.2.2) upgrade, or other factors.
The state of the cluster at the time of the incident:

.rgw.bucket.index.pool is the pool with rgw's index objects, right?
The actual on-disk directory for one of those pgs would contain only
empty files -- the actual index data is stored in the osd's leveldb
