    iSCSI – when it gets crouded

    2013-03-04 15:37 | Autor: jekader | Filed under: FedoraMD, Jekader

    итак, после какого-то времени использования iSCSI произошло закономерное: некоторые диски заполнились.
    К счастью, диски были созданы через lvm, так что расширение их было делом пары команд:
    1) отмонтируем файловую систему на инициаторе ("клиенте"):
    umount /path/to/mountpoint
    2) тормозим демон iscsi на клиенте:
    /etc/init.d/iscsi stop
    3) находим ID и LUN для интересующего нас диска на таргете ("сервер"):
    tgtadm --op show --mode target
    вывод примерно такой:
    Target 2: iqn.2013-01.net.test:nas.jekader
    System information:
    Driver: iscsi
    State: ready
    I_T nexus information:
    LUN information:
    LUN: 0
    Type: controller
    SCSI ID: IET 00020000
    SCSI SN: beaf20
    Size: 0 MB
    Online: Yes
    Removable media: No
    Backing store type: rdwr
    Backing store path: None
    LUN: 2
    Type: disk
    SCSI ID: IET 00020002
    SCSI SN: beaf22
    Size: 32212 MB
    Online: Yes
    Removable media: No
    Backing store type: rdwr
    Backing store path: /dev/mapper/stripe_vg-jekader
    Account information:
    ACL information:
    192.168.8.88
    здесь нас интересуют строки Target 2 и LUN: 2

    3) отключаем расшаренный диск, указав его ID и LUN,

    LVM-based RAID0

    2012-11-15 23:10 | Autor: jekader | Filed under: FedoraMD, Jekader

    Recently I decided to experiment with more "advanced" LVM features, such as creating a logical volume on multiple physical ones. Here I'll tell you the steps necessary to create a RAID0 (stripe) array on 4 hard drives: sdb sdc sdd sde, 500GB each.
    (mai mult…)
