Failed to attach volume Data to VM Nas12U41; org.libvirt.LibvirtException: internal error: unable to execute QEMU command '__com.redhat_drive_add': could not open disk image /mnt/3c164f13-17f2-3edf-b836-74299f20a559/65bcbd35-4fc5-4714-af04-4712a6a7f0e7: qcow2: Image is corrupt; cannot be opened read/write
you may want to check if the storage is healthy, and the file exists and is healthy. Depending on what filesystem and primary storage you're using you may run fsck or equivalent to recover the corrupted file. You may also want to check file permissions. Can you share your CloudStack version, output of "virsh version", "qemu-img info" on the qcow2 file and KVM host distro.
To discuss further pl join the CloudStack users mailing list and ask there http://cloudstack.apache.org/mailing-lists.html

I am trying to run the example grakn migration "phone_calls" (using python and JSON files).
Before reaching there, I need to load the schema, but I am having trouble with getting the schema loaded, as shown here: https://dev.grakn.ai/docs/examples/phone-calls-schema
System:
-Mac OS 10.15
-grakn-core 1.8.3
-python 3.7.3
The grakn server is started. I checked and the 48555 TCP port is open, so I don't think there is any firewall issue. The schema file is in the same folder (phone_calls) as where the json data files is, for the next step. I am using a virtual environment. The error is below:
(project1_env) (base) tiffanytoor1#MacBook-Pro-2 onco % grakn server start
Storage is already running
Grakn Core Server is already running
(project1_env) (base) tiffanytoor1#MacBook-Pro-2 onco % grakn console --keyspace phone_calls --file phone_calls/schema.gql
Unable to create connection to Grakn instance at localhost:48555
Cause: io.grpc.StatusRuntimeException
UNKNOWN: Could not reach any contact point, make sure you've provided valid addresses (showing first 1, use getErrors() for more: Node(endPoint=/127.0.0.1:9042, hostId=null, hashCode=5f59fd46): com.datastax.oss.driver.api.core.connection.ConnectionInitException: [JanusGraph Session|control|connecting...] init query OPTIONS: error writing ). Please check server logs for the stack trace.
I would appreciate any help! Thanks!
Nevermind -- I found the solution, in case any one else runs into a similar problem. The server configuration file needs to be edited: point the data directory to your project data files (here: the phone_calls data files) & change the server IP address to your own.
I am running owncloudcmd to sync files from a local* path to an ownCloud/Nextcloud server, all running Debian 8. However it fails with the error:
[5] csync_statedb_query sqlite3_compile error: disk I/O error - on
query PRAGMA quick_check; [6] csync_statedb_load ERR: sqlite3
integrity check failed - bail out: disk I/O error. #### ERROR during
csync_update : "CSync failed to load the journal file. The journal
file is corrupted."
I am not very familiar with csync or sqlite so I am a bit in the dark and although I can find talk of this issue through googling, I can't find a fix. The data in this case can be dumped to start over so I'm happy to flush any database or anything else. I've trying removing the created csync and journal files assuming one of them was corrupted but it doesn't seem to change anything.
I have read talk about changing PRAGMA settings to ignore the error (or check) but I can't see how this is implemented either.
Is anyone able to show me how to clear out the corruption?
*the local file is a mounted path to an AWS S3 bucket but I think this is irrelevant because it is working on other systems fine.
I have installed devstack on ubuntu 14.04 and have rebooted Virtual Machine, but after reboot openstack is not working and getting the following errors:
Overview -> Error: Unable to retrieve usage information
Instances -> Error: Unable to retrieve instances.
Volumes -> Error: Unable to retrieve snapshot list.
Images -> Error: Unable to retrieve images.
As I have found the solution on stack overflow, there is no ./rejoin-stack to retain all the Virtual Machines
So I am trying to execute the command inside devstack directory i.e.
cd devstack
$devstack screen -c stack-screenrc
By running above command, I found that Virtual machine network interfaces are automatically created and by this the physical wired connection is getting disconnected.
I have attached the screen shot of network interfaces created.
Can anyone help me please,
Thanks
Any inputs??
I am getting started with Ethereum and building a Dapp (what the hell does this mean by the way?). On the basic installation of the application (https://github.com/ethereum/wiki/wiki/Dapp-using-Meteor#connect-your-%C3%90app), I get this error upon attempting to connect.
geth --rpc --rpccorsdomain "http://localhost:3000"
I0804 23:48:24.987448 ethdb/database.go:82] Alloted 128MB cache and 1024 file handles to /Users/( . )Y( . )/Library/Ethereum/chaindata
Fatal: Could not open database: resource temporarily unavailable
I literally just got started, I set up ethereum through homebrew and made an account with geth. Can't get past right here.
Thank you!
Your geth client is already running in the background. You can attach to it by typing:
$ geth attach
in your command line. This will allow you to run commands on the geth client console.
I'm trying to create a database using DBCA on Oracle 11g installation on Ubuntu Linux 12.04 64 bit.
I followed the instructions here, but I get
ORA-12547: TNS Lost Contact when running DBCA.
Below are the details. Can someone assist with the solution?
Instead of using /opt/oracle as the "oracle" user home, I used /home/oracle
I did not install the libstdc++5 in 32 bit version
I did everything else the same as the posting
Installation resulted in "missing packages". I tried to do an apt-get install for these packages from ubuntu, but ubuntu says that they don't exist.
Then I saw in the instructions:
Once you will reach the "pre-reqs" screen, check "Ignore all" to continue the installation.
When running ./dbca from $ORACLE_HOME/bin, it fails with ORA-12547.
I checked $ORACLE_HOME/network/admin and listener.ora , sqlnet.ora , and tnsnames.ora all look OK.
However, I think that tnsnames.ora is not being read properly, because ./tnsping fails and the error message states that "EZ Connect" was used.
But in my sqlnet.ora , I have
names.directory_lookup = (TNSNAMES,EZCONNECT)
It should use EZ Connect only after tnsnames is tried.
Also, I sometimes get ORA-12541: No listener. I tried running ./netca. Everything is OK until I perform a test on the listener, and it fails.
I can't run ./lsnrctl. Absolutely nothing happens for this, as well as lsnrctl start, stop, status.
I can't go through sqlplus. If I run ./sqlplus , it asks me for username/password directly.
If I do ./sqlplus / as sysdba, then this results in "ORA-12547: TNS lost contact".
All environment variables are set correctly in .bashrc.
I tried re-running root.sh , but the problem is not fixed.
/etc/oratab is OK
/etc/hosts is OK, but I can't always ping the "localhost" or "127.0.0.1", or "ubuntu" or "127.0.1.1"
The same TNS or Listener errors display.
When I login in oracle (sqlplus system/pass as sysdba), I got this:
ERROR:
ORA-12547: TNS :lost contact when try to connect to Oracle.
First, I think the server is down, but I check it, it is OK. And so many body say 'chmod 6751 oracle', I did it, but I got another error:
ERROR:
ORA-01031: insufficient privileges
Enter user-name:
finally, I switch the system user from root to oracle. And I login success.
Ensure the DB is up and running and you can connect locally AS SYSDBA to the database
using Oracle binaries owner (usually oracle:oinstall Unix / Linux user). If it does not
work, probably you encounter a different problem.
1. Check privileges of an Oracle file on Unix / Linux host where database is running:
cd $ORACLE_HOME/bin
ls -ltr oracle
2. Change permissions as below:
chmod 6751 oracle
ls -ltr oracle
This code may help you lot.
