I tried setting noout and that did provide a bit better result.
Basically I could stop the OSD on the inactive server and everything
still worked (after a 2-3 second pause) but then when I rebooted the
inactive server everything hung again until it came back online and

Hi all,
Kind of new to Ceph (have been using 10.2.11 on a 3-node Proxmox 4.x cluster
[hyperconverged], works great!) and now I'm thinking of perhaps using it for a
bigger data storage project at work, a PoC at first, but built as correctly as
possible for performance and availability. I have th
Hello,
this is where (depending on your topology) something like:
---
mon_osd_down_out_subtree_limit = host
---
can come in very handy.
Provided you have correct monitoring, alerting and operations, recovering
a down node can often be restored long before any recovery would be
finished and you a

I went through this as I reformatted all the OSDs with a much smaller cluster
last weekend. When turning nodes back on, PGs would sometimes move, only to
move back, prolonging the operation and system stress.
What I took away is it’s least overall system stress to have the OSD tree back
to tar
Dear Chris,
Thanks for your feedback. The node/OSDs in question are part of an erasure
coded pool and during the weekend the workload should be close to none.
But anyway, I could get a look on the console and on the server; the power is
up, but I cant use any console, the Loginprompt is shown,
It sort of depends on your workload/use case. Recovery operations can be
computationally expensive. If your load is light because its the weekend
you should be able to turn that host back on as soon as you resolve
whatever the issue is with minimal impact. You can also increase the
priority
Hi,
one host out of 10 is down for yet unknown reasons. I guess a power failure. I
could not yet see the server.
The Cluster is recovering and remapping fine, but still has some objects to
process.
My question: May I just switch the server back on and in best case, the 24 OSDs
get back online

Hi!
I just had the time to check again: even after removing the broken
OSD, mgr still crashes.
All OSDs are on and in.
If I run "ceph balancer on" on a HEALTH_OK cluster, an optimization
plan is generated and started. After some minutes all MGRs die.
This is a major problem for me, as I still got

Hi,
I have a fileserver which mounted a 4TB rbd, which is ext4 formatted.
I grow that rbd and ext4 starting with an 2TB rbd that way:
rbd resize testpool/disk01--size 4194304
resize2fs /dev/rbd0
Today I wanted to extend that ext4 to 8 TB and did:
rbd resize testpool/disk01--size 8388608
