Thanks, the used procedure seems solid.

In addition, how full are your DB/WAL drives?

Kind regards,
David

Re: [PVE-User] [Extern] - Re: "nearfull" status in PVE Dashboard not consistent

[Frank Thommen]

How/where can I see that? All commands that I found so far, only print 
out size and/or usage of the OSDs themselves. Also with LVM commands I 
only managed to see the size of the DB LVs, but not the current usage.

I will have a look. However, not having real working experience with 
Ceph, using an external balancer requires a "leap of faith" from my side :-)

Re: [PVE-User] [Extern] - Re: "nearfull" status in PVE Dashboard not consistent

[Frank Thommen]

I'm not sure, if that is related, but looking at the activity LEDs of 
the DB/WAL SSD devices (two SSDs in RAID 1 each) in each host, the 
device in one host is basically permanently active (LEDs constantly 
flickering w/o pause), while on the other host, the device seems almost 
completely inactive (one blink every few seconds). The third host has no 
SSD DB device yet. To me that looks, as one Ceph node is extremely 
active, while the other isn't. That also looks like an imbalance to me.

Re: [PVE-User] [Extern] - Re: "nearfull" status in PVE Dashboard not consistent

[Daniel Oliver]

The built-in Ceph balancer only balances based on PG numbers, which can vary wildly in size for several reasons.

I ended up disabling the built-in balancer and switching to https://github.com/TheJJ/ceph-balancer, which we now run daily with the following parameters:
placementoptimizer.py balance --ignore-ideal-pgcounts=all --osdused=delta --osdfrom fullest

This keeps things nicely balanced from a fullness perspective, with the most important bit being ignore-ideal-pgcounts, as it allows balancing decisions outside of what the built-in balancer would decide.

The OSDs are of different size, because we have 4 TB and 2 TB disks in
the systems.

We might give the reweight a try.

[Frank Thommen]

The OSDs are of different size, because we have 4 TB and 2 TB disks in 
the systems.

We might give the reweight a try.

Hi Frank,

The images didn't work :)

Pool and osd nearfull are closely related, when OSD's get full your pool also gets nearfull as Ceph needs to be able to follow the crush rules,
which it can't if one of the OSD's gets full, hence it warns when it gets nearfull.

I see that you're mixing OSD sizes, deleting and recreating the OSD's one by one caused this, as the OSD's got new weights you should be OK when you reweight them.
You can do this by hand or using reweight-by-utilization, what you prefer.

Not quite sure about the pool sizes, but an RBD pool with a 2/3 min/max rule should never be above 80%, as this gives you a nearfull pool when it starts backfilling when you lose one node, or even a full pool worst case, rendering the pool read only.

Kind regards,
David

Yes, but Ceph also reports five(!) nearfull pools, but the pool overview doesn't reflect that. I'd love to show this with CLI, but I could not find an appropriate command so far. Hopefully, inline images work:

 From the Ceph overview dashboard:

And from the pool overview

Two pools are quite full (80% and 82%), but far from nearfull, and the other tree are basically empty.

Re: [PVE-User] [Extern] - Re: "nearfull" status in PVE Dashboard not consistent

[Frank Thommen]

Yes, but Ceph also reports five(!) nearfull pools, but the pool overview 
doesn't reflect that. I'd love to show this with CLI, but I could not 
find an appropriate command so far. Hopefully, inline images work:

 From the Ceph overview dashboard:

And from the pool overview

Two pools are quite full (80% and 82%), but far from nearfull, and the 
other tree are basically empty.

[Frank Thommen]

pasteboard.co seems to be out-of-order at the time. Are there good 
alternatives? It would really be easier, if I could just send 
attachments to the list :-/

Those OSD are nearfull, if you have the default 0.85 value for that. You 
can try to lower a bit their weight.
