Não consigo verificar, algo está errado com o Github agora. Se não estiver certo, o que devo mudar?
Posso conectar minha instância AWS EC2
ssh -i "pizdform.pem" [email protected]
Last login: Tue Feb 21 12:36:50 2023 from ...
Eu tentei ping Ansible
cat test-project/hosts.ini
[web]
52.206.23.6
ansible -i test-project/hosts.ini web -m ping -u ec2-user
falha no ping

Por que?
eu verifiquei lshw
sudo lshw -C disk

eu tentei montar
sudo mount /dev/sda /mnt/mydrive

Como verificar opção ruim ou superbloco ruim?

Qual é a diferença entre os dois IPs privados?
Eu tenho dois SSDs, o primeiro está quase cheio. Esta é a saída lsblk

E esse processo está se repetindo de novo e de novo.
apaguei skip=grant-tablesdo meu /etc/my.confarquivo
Eu tentei o que o bart sugeriu, funcionou em primeiro lugar, mas depois tenho o mesmo problema.
I logged as a root.

Query OK, 1 row affected (0.05 sec)

Como consertar isto?

Por quê?
Eu tenho um SSD antigo de 120 GB
lsscsi -s
[0:0:0:0] disk ATA GOODRAM 10.8 /dev/sda 120GB
[1:0:0:0] disk ATA TOSHIBA DT01ACA1 A750 /dev/sdb 1.00TB
[2:0:0:0] cd/dvd TSSTcorp CDDVDW SH-222AB SB00 /dev/sr0
Pelo que entendi, tenho 4 slots na minha placa-mãe
lsscsi -H
[0] ahci
[1] ahci
[2] ahci
[3] ahci
Comprei Crucial MX500
Se eu inseri-lo no último slot livre, como será minha operação? Ou talvez seja melhor trocar o SSD antigo pelo novo, nesse caso eu tenho que instalar o novo Ubuntu novamente?
