Hi Anthony, thanks for reaching out.
Erasure data pool (K=4, M=2) but I had more than two disk failures around
the same time and the data had not fully replicated / restored elsewhere in
the cluster.
They are big 12TB Exos so it usually takes a few weeks to backfill /
recover plus I had snaptrimm
I have been digging for a while on how to minimize STDDEV of the
distribution of data on my OSDs and I can't seem to get it to get below 12.
I have other clusters that have a STDDEV of 1 which is my goal. But this
cluster is really giving me fits. This cluster started off on the
Emperor. Might
Hi,
please forgive me if this has been asked before - I could not find any
information on this topic.
I am using ceph with librados via the phprados extension. Since upgrading to
the current ceph versions where OpenSSL is used in in librados, I observe that
using PHP's libcurl integration and
Hi Andrej,
That doesn't sound right -- I checked a couple of our clusters just
now and the mon filesystem is writing at just a few 100kBps.
debug_mon = 10 should clarify the root cause. Perhaps it's logm from
some persistent slow ops?
Cheers, Dan

Hello all, I'd really appreciate some input from the more knowledgeable
here.
Is there a way I can access OSD objects if I have a BlueFS replay error?
This error prevents me starting the OSD and also throws an error if I try
using the bluestore or objectstore tools. - I can however run a
ceph-blu

Hi,
on our large ceph cluster with 60 servers, 1600 OSDs, we have observed
that small system nvmes are wearing out rapidly. Our monitoring shows
mon writes on average about 10MB/s to store.db. For small system nvmes
of 250GB and DWPD of ~1, this turns out to be too much, 0.8TB/day or
1.5PB i
Just one addition from my test, I believe I misinterpreted my results
because my test image was named "test" and the client "TEST", so the
rbd_id. is indeed upper case for an image that has an
upper-case name. So forget my comment about that.
Another question though: does the image you're try
Actually I didn't try other caps.
The setup of RBD images and authorizations is automised with a bash
script that worked in the past w/o issues.
I need to understand the root cause in order to adapt the script
accordingly.
