I know I'm not even close to this type of a problem yet with my small
cluster (both test and production clusters) - but it would be great if
something like that could appear in the cluster HEALTHWARN, if Ceph could
determine the amount of used processes and compare them against the current
limit
Hi all,
After the previous thread, I'm doing my SSD shopping for and I came across
an SSD called an Edge Boost Pro w/ Power Fail, it seems to have some
impressive specs - in most places decent user reviews, in once place a poor
one - I was wondering if anyone has had any experience with these
Hi all,
In my reading on the net about various implementations of Ceph, I came
across this website blog page (really doesn't give a lot of good
information but caused me to wonder):

Hi all,
I've only been using ceph for a few months now and currently have a small
cluster (3 nodes, 18 OSDs). I get decent performance based upon the
configuration.
My question is, should I have a larger pipe on the client/public network or on
the ceph cluster private network? I can only have

Hi all,
I have a small cluster together and it's running fairly well (3 nodes, 21
osds). I'm looking to improve the write performance a bit though, which I
was hoping that using SSDs for journals would do. But, I was wondering
what people had as recommendations for SSDs to act as journal
(the speeds of 240 is a bit better than
120s). and i've left 50% underprovisioned. I've got 10GB for journals and I
am using 4 osds per ssd.

Now, I've never setup a journal on a separate disk, I assume you have 4

So with this, will even numbers then be LTS? Since 9.0.0 is following
0.94.x/Hammer, and every other release is normally LTS, I'm guessing
10.x.x, 12.x.x, etc. will be LTS...

Hi all,
I have a cluster of 3 nodes, 18 OSDs. I used the pgcalc to give a
suggested number of PGs - here was my list:
Group1 3 rep 18 OSDs 30% data 512PGs
Group2 3 rep 18 OSDs 30% data 512PGs
Group3 3 rep 18 OSDs 30% data 512PGs
Group4 2 rep 18 OSDs 5% data 256PGs
Group5 2
Sounds to me like you've put yourself at too much risk - *if* I'm reading
your message right about your configuration, you have multiple hosts
accessing OSDs that are stored on a single shared box - so if that single
shared box (single point of failure for multiple nodes) goes down it's
