Hi all,
There is an error message when I run “ceph-deploy osd activate…..”
Before that, I have run “ceph-deploy osd prepare t-ceph-01:/mnt/dev/
t-ceph-02:/mnt/dev/” successfully
Does anyone know the reason? Anything I did wrongly?
Thank you.
ceph@t-ceph-01:/home/ubuntu$ ceph --version

This is because of the min_size specification. I would bet you have it set
at 2 (which is good).
ceph osd pool get rbd min_size
With 4 hosts, and a size of 3, removing 2 of the hosts (or 2 drives 1 from
each hosts) results in some of the objects only having 1 replica
min_size dictates that IO fre
Hi.
I have rebuild my ceph yesterday with the latest master branch and the
problem still occurs.
I also found that the number of receive errors will increase during the
testing (/sys/class/infiniband/mlx4_0/ports/1/counters//port_rcv_errors)
and I think that is the reason why the osd's connection
Hi,
rbd_id.vm-100-disk-1 is only a "meta object", IIRC, it's contents will get
you a "prefix", which then gets you on to rbd_header.,
rbd_header.prefix contains block size, striping, etc. The actual data
bearing objects will be named something like rbd_data.prefix.%-016x.
Example - vm-100-disk-1

Jason, thanks for the reply, you really got my question right.
So, some doubts that might show that i lack of some general knowledge.
When i read that someone is testing a ceph cluster with secuential 4k
block writes, does that could happen inside a vm that is using an RBD
backed OS ?
In that case

It's a very broad question -- are you trying to determine something
more specific?
Notionally, your DB engine will safely journal the changes to disk,
commit the changes to the backing table structures, and prune the
journal. Your mileage my vary depending on the specific DB engine and
its configu

i'm not an expert but here is my understanding of it. a hit_set keeps track
of whether or not an object was accessed during the timespan of the
hit_set. for example, if you have a hit_set_period of 600, then the hit_set
covers a period of 10 minutes. the hit_set_count defines how many of the
hit_se
