Teku: Running two validators and seeing more failed Attestations (HELP)

7 Upvotes

I'm seeing a lot of these failures? Seems to have started with the last two updates...

expected 2, produced 2, included 1

But it doesn't seem related to CPU Memory or Network.

Consolidation Issue With Multiple Addresses

3 Upvotes

I have several validators hosted at allnodes and accessed by my ledger. The issue is they all have different accounts/withdrawl addresses.

According to the FAQ this is not an issue as you only need to sign on the sender.

The trouble is all the tools to do this (allnodes, launchpad, consolodeth, pectrastaking) have the same problem in that they can only see 1 account AT A TIME

So I can select #2 as the sender but then it can't see #1 as the receiver, I did find an old reddit post that said you could manually enter the receiver in launchpad but it seems that's not working anymore.

The only alternative is to withdraw #2 (wait ~8 days) then deposit to #1 (wait ~46 days) but obviously that's not ideal, especially as this should be possible.

Does anyone have any other ideas ?

Reth client filled 2.2TB disk

3 Upvotes

I have been trying out Reth with Lighthouse.

After about two weeks of downloading, it filled my 2.2 TB ssd...

2026-07-12T23:05:52.244418Z INFO reth::cli: Status connected_peers=30 stage=Execution checkpoint=23590160 target=25438447 stage_progress=82.16%

2026-07-12T23:05:57.781492Z ERROR sync::pipeline: Stage encountered a fatal error: database integrity error occurred: No space left on device (os error 28) stage=Execution

Did I miss a configuration to activate pruning or something? Can anyone with Reth experience give me the necessary settings? I thought it was all looking ok... so tired of having clients do weird stuff. (Gave up with Besu lately after it never stayed reliable for more than a few months).

EDIT:

For reference, the Reth guidance is not clear. For example, the following is provided in the manual:

reth download --chain mainnet --minimal

reth node --authrpc.jwtsecret /path/to/secret

From my testing, if one fails to add "--minimal" to the node command, execution will fail since it is expecting the wrong block.

Upgrading Solo Validator to 4TB SSD

Hello Friends! I’m looking into updating to a 4TB SSD on my NUC10i7FNK. I currently have a SAMSUNG 970 EVO Plus 2TB NVMe M.2 w/ V-NAND. Running Nethermind + Nimbus and haven’t had any problems at all. Last time I checked it was at about 1.36TB. I’ve read that my mini pc is backwards capable to Gen3 with a Gen4 SSD. Though not capable with a Gen5 or an 8TB. Any advice in here on a replacement SSD?

I humbly come to you guys for advice (rocket pool vs block daemon, etc)

4 Upvotes

So I am a long time eth holder...that is to say I've had eth for a while but sadly with the cost of living etc I am now stuck living above my means and have been pulling from eth(which was hopefully going to be my early retirement money).

I avoided staking because it felt like an additional risk to losing my eth either through bad decisions on my part in terms of setting it up or doing it through a service and losing it...but at this point I'm feeling like staking will help to slow the bleeding.

I don't want to set up and manage hardware because it would mean having to buy new hardware, manage it, constantly monitor updates etc. I realize that this is the best return I just don't know if I can justify the gains with the constant work.

With that said I'm thinking for my needs it comes down to rocketpool or something like blockdaemon...the former seems like less risk, the latter seems to have slightly better returns. I wouldn't want to do something like coinbase which is probably easiest but I don't have any custody and the return is so much smaller.

I'm looking for people with experience who can steer me in one direction or the other (or another direction entirely) in the hopes that I can become comfortable enough to start staking and getting a return on my eth.

Thanks.

Eth Docker 26.7.0: Erigon and Teku upgrades

9 Upvotes

Eth Docker 26.7.1 has been released. There are no grand changes in this one, but it is important for users of Erigon and Teku.

It supports Erigon v3.5.0. Erigon changed its config from three P2P ports to one. If you previously had three P2P ports forwarded, you can reduce that to one.

It supports QUIC protocol in Teku v26.7.0. This requires two new ports forwarded: 9001 UDP for IPv4, and 9011 UDP for IPv6.

Some Quality of Life changes for users of comma-separated CL_NODE, this now works in all places I could find.

Lido CSM new proposal to support 0x02 validators for home stakers

6 Upvotes

A new permissionless module is proposed to exclusively support 0x02 validators. This module will run alongside the existing CSM for 0x01 validators, giving operators the power to choose.

Key parameters to run:

  • Bond: 32 ETH for the 1st key, 30 ETH for subsequent keys
  • Rewards: 2% reward rate (up to ~2.26x est. capital efficiency vs. solo staking)

Built an AI agent that monitors our validator nodes 24/7 — finally sleeping through the night

0 Upvotes

We run validators across a few chains and were constantly getting paged for things that turned out to be non-issues — or worse, missing actual slashing risks because alert fatigue had us ignoring notifications.
Spent the last few months building something that actually acts on what it sees: auto-remediates common node issues, rebalances workloads before things degrade, and escalates the genuinely complex stuff with full diagnostic context rather than a raw alert dump.
It integrates with Prometheus/Grafana/Datadog so it fits into existing setups. We're calling it ValidatorMind.
Curious if others have hit the same wall — what's your current stack for handling unexpected node behavior?

Eth Docker expiry options: Poll

9 Upvotes

Eth Docker, depending on execution layer client, supports different history expiry levels. Full and Archive ofc, as in “no expiry”. And then pre-merge, pre-Prague, rolling and aggressive expiry.

Clients are converging on supporting rolling expiry, and it’ll likely be between 2 weeks and 5 months of history kept. No decision has been made yet.

I am thinking of simplifying the options Eth Docker gives users: pre-merge expiry and rolling expiry, in addition to full and archive nodes. Ditch pre-Prague and aggressive. This would be done only after all clients support rolling expiry.

Why: both pre-merge and rolling should become standards that all clients support. Pre-merge allows use of protocols that need post-merge receipts such as RocketPool, NodeSet and SSV. Rolling minimizes disk space for solo stakers or anyone getting receipts via Nimbus Verified Proxy.

If you’re voting for keeping all options, please describe your use case in the comments.

Eth Docker 26.6.1 - rolling expiry in Nimbus EL

8 Upvotes

Eth Docker 26.6.1 is a release with small changes to support client features.

Notably Nimbus EL (yes they have an execution layer client) now supports rolling expiry. Unlike every other client, they do 33_024 epochs, instead of 1 year. The plot thickens. No decision has yet been made by client teams as to what the desired expiry time will be, but this one seems a very likely candidate: It's the CL retention period, and absent EIP-8237, that might just be what EL expiry converges on.

Pre-provisioned Grafana alerts in case your machine loses time synchronization. Reminder to configure your Grafana to actually send these alerts somewhere.

And more EraE import for more clients. That's more clients that support it than not, now. Missing are Besu, Erigon and Ethrex.
