Thanks for the reply
I moved the 6.8.8 and the JSON parsing error seems gone. I am trying to do a
simple request though I have very weird results:

Hi,
I deployed a multisite in order to sync data from a mimic cluster zone
to a nautilus cluster zone. The data sync well at present. However,
I check the cluster status and I find something strange. The data in my
new cluster seems larger than that in old ones. The data is far from full
synced
Hi,
I had configured a cache tier with below parameters:
cache_target_dirty_ratio: 0.1
cache_target_dirty_high_ratio: 0.7
cache_target_full_ratio: 0.9
The cache tier did improved the performance much. And I am targeted to keep
the cache tier with only 10% of dirty data. Remaining data ( 80% )
Hi all,
We have several nfs servers providing file storage. There is a nginx in
front of
nfs servers in order to serve the clients. The files are mostly small files
and
nearly about 30TB in total.
I'm gonna use ceph rgw as the storage. I wanna know if it's appropriate to
do so.
The data
For assessing the criticality of the MGR beacon loop of doom outage, during my
somewhat desperate attempts to get this under control, I saw this here:
-
[root@gnosis ~]# ceph status
cluster:
id: ---
health: HEALTH_WARN
no active mgr
For everyone who does not want to read the details below: I run now with
(dramatically?) increased beacon grace periods for OSD (3600s) and MGR (90s)
beacons and am wondering what the downside of this is and if there are better
tuning parameters for my issues.

Hi Lenz,
I'm wondering
I had a 1x replicated fs data test pool, when a osd died I had '1 pg
stale+active+clean of cephfs'[1] after a cluster reboot this turned into
'1 pg unknown'
ceph pg repair did not fix anything (for stale and unknown state)
I recreated the pg with:
ceph osd force-create-pg pg.id

Hi,
After a major crash in which we lost few osds, we are stucked with
incomplete pgs.
At first, peering was blocked with peering_blocked_by_history_les_bound.
Thus we set osd_find_best_info_ignore_history_les true for all osds
involved in the pg and set the primary osd down to force
OK, the command finally executed and it looks like the cluster is running
stable for now. However, I'm afraid that 90s might not be sustainable.
Questions: Can I leave the beacon_grace at 90s? Is there a better parameter to
set? Why is the MGR getting overloaded on a rather small cluster with
Hi all,
another client-load induced meltdown. It is just starting and I hope we get it
under control. This time, its the MGRs failing under the load. It looks like
thay don't manage to get their beacons to the mons and are kicked out as
unresponsive. However, the processes are fine and up. Its
Hello all,
I'm having an issue with a bucket that refuses to be resharded..for the record,
the cluster was recently upgraded from 13.2.4 to 13.2.10.

Hi,
I have created an erasure coded pool and the below default parameters
related to stripe sizes are present.
"osd_pool_erasure_code_stripe_width": "4096" --> 4KB
"rgw_obj_stripe_size": "4194304" --> 4MB
Let say the k+m values are 10+5 for the erasure pool, and we upload an
object of let say,

Hi Anthony and Phil,
since my meltdown case was mentioned and I might have a network capacity issue,
here a question about why having separate VLANS for private and public network
might have its merits:
In our part of the ceph cluster that was overloaded (our cluster has 2 sites

Thank you Eric. That 'sounds like' exactly my issue. Though I'm surprised to
bump into something like that on such a small system and at such low bandwidth.
But the information I can find on those parameters is sketchy to say the least.
Can you point me at some doco that explains what they
Interestingly, I have found that if I limit the rate at which data is written
the tiering behaves as expected.
I'm using a robocopy job from a Windows VM to copy large files from my existing
storage array to a test Ceph volume. By using the /IPG parameter I can roughly
control the rate at

Hi Stefan,
I don't have specific preferences, hence any public storage you prefer.
Just one note - I presume you collected the logs for the full set of 10
runs. Which is redundant, could you please collect detailed logs (one
per OSD) for single shot runs.
Sorry for the unclear previous
Hi all,
I'm a newbie to Ceph. I'm an MSP and a small-scale cloud hoster. I'm
intending to use Ceph as production storage for a small-scale private hosting
cloud. We run ESXi as our HVs so we want to present Ceph as iSCSI.
We've got Ceph Nautilus running on a 3-node cluster. Each node
Hello,
I stumbled across that weird behaviour today - after initially creating disks
and DB LVs on NVMe (using ceph-ansible) - second run of ceph-volume ends up
with an error:

Hi,
I'm interested in the Swift extract archive/bulk upload feature [1].
First I thought that this feature is not implemented in radosgw, as it
is not mentioned anywhere in the docs [2] and some test requests of mine
were not successful. However, while browsing the issue tracker, I found
some
