Hi Christian,
Thank you for your help.
Ceph version is 12.2.2. So is this value bad ? Do you have any suggestions ?
So to reduce the max chunk ,I assume I can choose something like
7 << 20 ,ie 7340032 ?

Hi Jason,

Yes, it is only used for storing metadata of ecpool.
We use 2 pools for erasure coding
ecpool - erasure coded datapool

All clusters are same hardware. Some have more disks and servers than
others. The only major difference is that this particular Ceph with this
problem, it had the noscrub and nodeep-scrub flags set for many weeks.

Hi,
We have set no scrub , no deep scrub flag on a ceph cluster.
When we are deleting snapshots we are not seeing any change in usage space.
I understand that Ceph OSDs delete data asynchronously, so deleting a
snapshot doesn’t free up the disk space immediately. But we are not seeing
any change
Thank you!
Ceph version is 12.2
Also, can you let me know the format to set osd_backfill_full_ratio ?
Is it " ceph osd set -backfillfull-ratio .89 " ?

Hi,
Initial PG count was not properly planned while setting up the cluster, so
now there are only less than 50 PGs per OSDs.
What are the best practises to increase PG number of a pool ?
We have replicated pools as well as EC pools.
Or is it better to create a new pool with higher PG numbers?

I have already purged it, so I cannot use the reweight option mentioned in

Thank you for your reply.
I created a erasure
only the data blocks can be stored in an EC pool. Therefore, when
creating the image, you should provide the "--data-pool "
optional to specify the EC pool name.

Hi,
I am trying to setup an erasure coded pool with rbd image.
The ceph version is Luminous 12.2.1. and I understand, since Luminous,
RBD and Cephfs can store their data in an erasure coded pool without use
of cache tiring.
I created a pool ecpool and when trying to create a rbd image, gets

If the cloned VM had written around 10Gbs of data, wouldn&#

"fast-diff" feature is enabled, note that it only calculates usage in
object size chunks (defaults to 4MB) -- which means that even writing
1 byte to a 4MB object would flag the object as dirty (it's an
upper-bound estimate).

Hello,
I noticed that when we create a snapshot of a clone, the first snapshot
seems to be quite large.
For example:
Clone VM is taking up 136MBs according to rbd du
First snapshot: 10GBs
Second snapshot: 104MBs
Third snapshot: 57MBs
The clone is a Windows virtual machine, which does take ar
Hi,
Not sure if this is a good/valid question.
I have deployed a lot of VMs in a ceph cluster that were cloned from an
original rbd image.
I want to see how much of the original image is a new VM (cloned image)
using. Is there any command to get such details?
