Block Storage¶
Membuat volume¶
- Dapatkan sumber kredensial - demountuk melakukan langkah-langkah berikut sebagai proyek non-administrasi:- $ . demo-openrc 
- Membuat volume 1GB: - $ openstack volume create --size 1 volume1 +---------------------+--------------------------------------+ | Field | Value | +---------------------+--------------------------------------+ | attachments | [] | | availability_zone | nova | | bootable | false | | consistencygroup_id | None | | created_at | 2016-03-08T14:30:48.391027 | | description | None | | encrypted | False | | id | a1e8be72-a395-4a6f-8e07-856a57c39524 | | multiattach | False | | name | volume1 | | properties | | | replication_status | disabled | | size | 1 | | snapshot_id | None | | source_volid | None | | status | creating | | type | None | | updated_at | None | | user_id | 684286a9079845359882afc3aa5011fb | +---------------------+--------------------------------------+ 
- Setelah waktu yang singkat, status volume harus berubah dari - creatingmenjadi- available:- $ openstack volume list +--------------------------------------+--------------+-----------+------+-------------+ | ID | Display Name | Status | Size | Attached to | +--------------------------------------+--------------+-----------+------+-------------+ | a1e8be72-a395-4a6f-8e07-856a57c39524 | volume1 | available | 1 | | +--------------------------------------+--------------+-----------+------+-------------+ 
Lekatkan volume ke sebuah instance¶
- Lekatkan volume ke sebuah instance: - $ openstack server add volume INSTANCE_NAME VOLUME_NAME - Ganti - INSTANCE_NAMEdengan nama instance dan- VOLUME_NAMEdengan nama volume Anda ingin lekatkan untuk itu.- Example - Lekatkan volume - volume1ke instance- provider-instance:- $ openstack server add volume provider-instance volume1 - Catatan - Command ini tidak memberikan output. 
- Buatlah daftar volumes: - $ openstack volume list +--------------------------------------+--------------+--------+------+--------------------------------------------+ | ID | Display Name | Status | Size | Attached to | +--------------------------------------+--------------+--------+------+--------------------------------------------+ | a1e8be72-a395-4a6f-8e07-856a57c39524 | volume1 | in-use | 1 | Attached to provider-instance on /dev/vdb | +--------------------------------------+--------------+--------+------+--------------------------------------------+ 
- Akses Anda misalnya menggunakan SSH dan menggunakan perintah - fdiskuntuk memverifikasi keberadaan volume sebagai perangkat penyimpanan blok- /dev/vdb:- $ sudo fdisk -l Disk /dev/vda: 1073 MB, 1073741824 bytes 255 heads, 63 sectors/track, 130 cylinders, total 2097152 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/vda1 * 16065 2088449 1036192+ 83 Linux Disk /dev/vdb: 1073 MB, 1073741824 bytes 16 heads, 63 sectors/track, 2080 cylinders, total 2097152 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/vdb doesn't contain a valid partition table - Catatan - Anda harus membuat sistem file pada perangkat dan me-mount itu menggunakan volume.
