Like Yacov said, you are targeting a v2.x lifecycle command against a v1.4.x peer, therefore an error is expected. When I tried the same thing on latest v1.4.10 peer, I get the following error back:

Hyperledger fabric peers panic due to previous block hash mismatch

Asked 2021-Jan-28 at 10:27

I have a hyperledger fabric network with 2 organizations and 2 peers per organization. I restored the network from backup and the peers started throwing the following error:

...

ANSWER

Answered 2021-Jan-28 at 10:27

You probably backed up the network by first backing up peers and then backing up orderers.

This is dangerous because then the backup you create results in peers being at a higher block height than the orderers.

As an example, imagine the orderers have a latest backed up block 100 and the peers have a latest backed up block 101 with hash of bar. The orderers will create block 101 with hash of foo and the peers will never need to pull it. Then, the orderers will create block 102 with previous hash foo but the peers expect a previous hash of bar.

Cassandra add node problem, failed; error='Cannot allocate memory' (errno=12)

ANSWER

The error message says that the JVM failed to commit memory, because mmap syscall returned with the error code 12 (ENOMEM).

This typically happens when the process reaches one of the OS memory limits:

The number of memory mappings exceeded vm.max_map_count sysctl limit. This is a quite common problem with Cassandra, since Cassandra tends to mmap thousands files, and the default limit is rather low - around 65K.

How to check: wc -l /proc//maps where is Java process ID.

How to fix: sudo sysctl vm.max_map_count=1000000
Total amount of the process' virtual memory exceeded RLIMIT_AS

How to check: ulimit -v, cat /proc//status | grep Vm

How to fix: ulimit -v unlimited before starting Cassandra in the same shell.
Overcommit is disabled, and the overcommit ratio is too low.

How to check: sysctl vm.overcommit_memory, sysctl vm.overcommit_ratio, cat /proc/meminfo

How to fix: sudo sysctl vm.overcommit_memory=0

EventStoreDB v5 Fail to run after using sudo

I normally run eventstore with eventstore --run-projections=System but trying to run queries, macos throw a security complain: “libjs1.dylib” cannot be opened because the developer cannot be verified.

So I ran sudo eventstore --run-projections=System. This did not fix the issue. I wen to system preferences > security > general and gave access to libjs1.dylib and the Query ran and returned no value.

I realized all the data from event store was gone.

I though maybe it becase sudo? I ran without sudo and now I get this error:

Have you checked the docs? https://developers.eventstore.com/server/5.0.9/server/server/default-directories.html#macos

The data isn't gone, but the database path for the root user won't match the path for the regular user, so your database has been created elsewhere.

Here is the docs note:

On macOS you will get permissions error if you run eventstore without sudo. We advise changing the configuration file and change the Db option to a place where you have access as the normal user.

When running with sudo, the database is located at /var/lib/eventstore. I suspect then when you run it without sudo, the database was places under /usr/local/Caskroom/eventstore/5.0.8/EventStore-OSS-MacOS-macOS-v5.0.8 somewhere.

Honestly, I avoid running EventStoreDB on macOS from the cask and use Docker instead. It's more predictable, doesn't have issues and allows you to run different versions without issues.

QUESTION

configuration to discover peers using mdns

Asked 2020-Oct-18 at 10:57

I am trying to make this example work. It is supposed to create two nodes with mdns support. Mdns is supposed to announce the peer every second, each peer is setup to print a statement once a peer is found.

When running it, the console output is merely empty. It prints out some garbage error in my concern: (node:51841) ExperimentalWarning: Readable[Symbol.asyncIterator] is an experimental feature. This feature could change at any time

How do i enable debugging log so that i can try to understand what is going on under the hood ? I would like to verify the mdns announce packets are issued, and possibly received, or not.

Alternatively, i am trying to use the bootstrap module to begin over wan peers, though expect it to be much slower, thus i would prefer to use mdns.

I tried to add various configuration and modules without much success, it is not clear to me if i am required to use the gossip module if i only want to announce some data on the dht. stuff like that.

any help is appreciated.

Cassandra node running, but cant connect?

Asked 2020-Sep-11 at 01:55

using Cassandra version 3.11.8, openjdk-8u242-b08

Prior to this crashing, I was altering a table with 50k+ columns so this might (is) a factor to all of this. I would Ideally rather lose the data in the commit (if its inserting a backlog still perpetually) so I can connect to the hosts so service can be resumed.

Before start of error, I started alter table commands inserting many columns into the table in calls of 1000 at a time. Eventually after it may have done about half of them i received this error for all the nodes.

2020-09-10 15:34:29 WARNING [control connection] Error connecting to 127.0.0.3:9042: Traceback (most recent call last): File "cassandra\cluster.py", line 3522, in cassandra.cluster.ControlConnection._reconnect_internal File "cassandra\cluster.py", line 3591, in cassandra.cluster.ControlConnection._try_connect File "cassandra\cluster.py", line 3588, in cassandra.cluster.ControlConnection._try_connect File "cassandra\cluster.py", line 3690, in cassandra.cluster.ControlConnection._refresh_schema File "cassandra\metadata.py", line 142, in cassandra.metadata.Metadata.refresh File "cassandra\metadata.py", line 165, in cassandra.metadata.Metadata._rebuild_all File "cassandra\metadata.py", line 2522, in get_all_keyspaces File "cassandra\metadata.py", line 2031, in get_all_keyspaces File "cassandra\metadata.py", line 2719, in cassandra.metadata.SchemaParserV3._query_all File "cassandra\connection.py", line 985, in cassandra.connection.Connection.wait_for_responses File "cassandra\connection.py", line 983, in cassandra.connection.Connection.wait_for_responses File "cassandra\connection.py", line 1435, in cassandra.connection.ResponseWaiter.deliver cassandra.OperationTimedOut: errors=None, last_host=None

I am running 8 nodes on a server. I have reset all nodes and handshakes are done. But I cannot make a connect to my cluster on any of the nodes.My system.log and debug.log have similar logs throughout once cassandra starts running. gc.log has not updated in some time so it makes me wonder what is going on? Interesting point is i only retrieve the list of columns in the table 3 times total, I have ran this code on my desktop without issues using 2 nodes (much much less resources) and have not received any of these issues.

Edit: just for clarity my application/connections are not running and these logs below are what is happening periodically..I tried looking at scheduled tasks and cannot find information about cassandra for this. I wonder what backlog its reading from and if I can stop it. Ideally I would like to stop this backload of operations from happening...

The timeout is from the driver trying to parse the schema while establishing the control connection.

The driver uses the control connection for admin tasks such as discovering the cluster's topology and schema during the initialisation phase. I've discussed it in a bit more detail in this post -- https://community.datastax.com/questions/7702/.

In your case, the driver initialisation times out while parsing the thousands of columns in the table you mentioned. I have to admit that this is new to me. I've never worked with a cluster that had thousands of columns so I'm curious to know what your use case is and perhaps there might be a better data model for it.

As a workaround, you can try to bump out the default timeout to see if the driver is able to eventually initialise. However, this is going to be a band-aid solution since the driver needs to parse the schema every time a DDL takes place. Cheers!

Unable to understand what wrong is going on after creating certifcates and replacing them in the ledger

Here are a few hints: Chaincode container startup has a default timeout of 300s. If chaincode instantiation takes longer than that (e.g. because you're on a very slow network), you'll get a timeout. You can try to extend that timeout by setting CORE_CHAINCODE_STARTUPTIMEOUT as env variable on your peer. To see what is happening during chaincode instantiation, perform a docker ps: you'll see some temporary containers running (based on image fabric-ccenv). Check their logs using docker logs.
