Redimensionando espao em disco em servidor linux sem LVM

  1. Primeiramente, redimensione o espao em disco do server no wmware, ou outro virtualizador;

  2. Inicia o server;

  3. Inicia o parted na vm:

root@srvubuntu02:~# parted /dev/sdaGNU Parted 3.3Using /dev/sdaWelcome to GNU Parted! Type 'help' to view a list of commands.(parted)
  1. Comando print para ver o esquema de partio e o tamanho dos volumes atuais:
(parted) printModel: VMware, VMware Virtual S (scsi)Disk /dev/sda: 26.8GBSector size (logical/physical): 512B/512BPartition Table: gptDisk Flags:Number  Start   End     Size    File system  Name  Flags 1      1049kB  2097kB  1049kB                     bios_grub 2      2097kB  21.5GB  21.5GB  ext4(parted)

4.1 Aps perceber que o "End" menor que o tamanho real do Disk sda, devemos inserir o comando resizepart 2 100%:

(parted) resizepart 2 100%Warning: Partition /dev/sda2 is being used. Are you sure you want to continue?

4.2. Ao ser questionado se deseja mesmo fazer as mudanas, digite Yes:

Yes/No? `Yes`

4.3. Escreva o novo tamanho total com "GB" ao final:

End?  [21.5GB]? 26.8GB
  1. Por fim, saia do parted com o comando quit
(parted) quitInformation: You may need to update /etc/fstab.
  1. Para ver as mudanas em disco:
root@srvubuntu02:~# fdisk -l /dev/sda | grep ^/dev/dev/sda1   2048     4095     2048   1M BIOS boot/dev/sda2   4096 52343750 52339655  25G Linux filesystem
  1. Percebe que no houve alterao real:
root@srvubuntu02:~# df -hFilesystem      Size  Used Avail Use% Mounted onudev            933M     0  933M   0% /devtmpfs           196M  1.3M  195M   1% /run/dev/sda2        20G  4.6G   14G  25% /tmpfs           977M     0  977M   0% /dev/shmtmpfs           5.0M     0  5.0M   0% /run/locktmpfs           977M     0  977M   0% /sys/fs/cgroup/dev/loop0       55M   55M     0 100% /snap/core18/1880/dev/loop1       30M   30M     0 100% /snap/snapd/8542/dev/loop2       72M   72M     0 100% /snap/lxd/16099tmpfs           196M     0  196M   0% /run/user/1000
  1. Por fim, aplica o comando para redimensionar o disco(sda2 neste caso):
root@srvubuntu02:~# `resize2fs /dev/sda2` _#Agora sim, redimensiona o disco_resize2fs 1.45.5 (07-Jan-2020)Filesystem at /dev/sda2 is mounted on /; on-line resizing requiredold_desc_blocks = 3, new_desc_blocks = 4The filesystem on /dev/sda2 is now 6542456 (4k) blocks long.
  1. Veja aplicado:
root@srvubuntu02:~# df -hFilesystem      Size  Used Avail Use% Mounted onudev            933M     0  933M   0% /devtmpfs           196M  1.3M  195M   1% /run/dev/sda2        25G  4.6G   19G  20% /tmpfs           977M     0  977M   0% /dev/shmtmpfs           5.0M     0  5.0M   0% /run/locktmpfs           977M     0  977M   0% /sys/fs/cgroup/dev/loop0       55M   55M     0 100% /snap/core18/1880/dev/loop1       30M   30M     0 100% /snap/snapd/8542/dev/loop2       72M   72M     0 100% /snap/lxd/16099tmpfs           196M     0  196M   0% /run/user/1000root@srvubuntu02:~#
