LIO target
TODO
Tundub, et 2018 sügisel on LIO (Linux-IO) kõige õigem lahendus iSCSI protokolli abil plokkseadme ressurssi üle nö tavalise ethernet võrgu kasutamiseks. Iseenesest LIO võimaldab teha muudki, LIO sisaldab
- erinevate back storage toetust (fail, partitsioon, lvm jt )
- erinevate andmevahetuse kanalite toetust (ethernet, fc jt)
Tööpõhimõte
LIO töötamisega ja sealhulgas võrgus nt iscsi teenuse pakkumisega ei kaasneb ühtegi user-space protsessi; tööd teeb kernel ja kerneli moodulid. iSCSI lahenduse määratlevad sellised objektid ja nende vahelised seosed
- plokkseade
- target portal
- lun
- acl
- initiatior (klient)
LIO target seadistatakse sysfs failisüsteemis /sys/kernel/config/target alla jääva osaga töötades. Muudatuste haldamist lihtsustab targetcli utiliit.
Tarkvara paigaldamine
2018 sügisel sobib Debian v. 9 keskkonnas öelda
# apt-get install targetcli-fb
CentOS v. 7 keskkonnas sobib öelda
# yum install targetcli
Seadistamine
Ettevalmistused
- vajalik on teada iscsi initiator arvuti iqn väärtust (olgu see nt iqn.1993-08.org.debian:01:aaaaaaaaaaa)
# cat /etc/iscsi/initiatorname.iscsi InitiatorName=iqn.1993-08.org.debian:01:aaaaaaaaaaa
- antud näites ei piirata ligipääsu iscsi ressursile parooliga, ainult kliendi iqn väärtusega (täindava ligipääsu saab seadistada nt paketifiltriga)
Käsuga
# targetcli
jõuab sysfs failisüsteemi haldamisse interaktiivsesse režiimi.
- plokkseadme kirjeldamine
/backstores/block create iscsi_block_1 /dev/vdb
- target iqn kirjeldamine ja portal kirjeldamine
/iscsi create iqn.2018-12.moraal.srv:storage.target03
- iqn kirjeldamine, millelt on lubatud ligi pääseda
/iscsi/iqn.2018-12.moraal.srv:storage.target03/tpg1/acls create iqn.1993-08.org.debian:01:aaaaaaaaaaa
- lun tekitamine ja sidumine targetiga
/iscsi/iqn.2018-12.moraal.srv:storage.target03/tpg1/luns create /backstores/block/iscsi_block_1
Paistab, et peale ülaltoodud käskude ütlemist muudatused kehtestatakse. Seadistused salvesatakse faili
/etc/rtslib-fb-target/saveconfig.json
Misc
- iqn eemaldamine, millelt on lubatud ligi pääseda
/iscsi/iqn.2018-12.moraal.srv:storage.target03/tpg1/acls delete iqn.1993-08.org.debian:01:aaaaaaaaaaa
- portal eemaldamine (praktiliselt lõpetatakse ka 0.0.0.0:3260/tcp kuulamine)
/iscsi/iqn.2018-12.moraal.srv:storage.target03/tpg1/acls delete 0.0.0.0 3260
- target ja block seade eemaldamine
/iscsi> /iscsi delete iqn.2021-01.tartu:storage.target01 /backstores> /backstores/fileio delete disc2_sda
Haldamine
root@cifs:~# targetcli sessions alias: pm-moraal-4-v52 sid: 1 type: Normal session-state: LOGGED_IN
LIO teenust käivitab
# systemctl status rtslib-fb-targetctl
LIO'ga tegelevad kerneli moodulid
# lsmod | grep ^target target_core_user 20480 0 target_core_pscsi 20480 0 target_core_file 20480 2 target_core_iblock 20480 2 ...
Võrgus teenindab kernel-space
# netstat -lnpt | grep -- - Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:3260 0.0.0.0:* LISTEN -
Tundub, et Proxmox peal saab kergesti hakata iscsi ressursse kaustama, aga kaustamist ära lõpetada polegi webgui kaudu võimalik, käsurealt sobib öelda
# iscsiadm -m session -P 1 # iscsiadm -m node -T iqn.2018-12.moraal.srv:storage.target02 -p 192.168.10.127 -u # iscsiadm -m node -T iqn.2018-12.moraal.srv:storage.target02 -p 192.168.10.127:3260 -o delete
Proxmox pealt kasutamiseks võib olla tark esmalt host peal /etc/lvm/lvm.conf peale seadistada filter ja global_filter
