Ma'ajiyar Tsaro ta Tsakiya (iSCSI) - Saita Client Initiator akan RHEL/CentOS/Fedora - Sashe na III

iSCSI Initiator su ne abokan ciniki waɗanda ke amfani da su don ingantattun sabar iSCSI don samun damar LUNs da aka raba daga sabar manufa. Za mu iya tura kowane nau'i na Operating Systems a cikin waɗancan faifan diski na cikin gida, kawai kunshin guda ɗaya ne kawai ake buƙatar shigar da su don samun tabbaci tare da uwar garken manufa.

  1. Za a iya sarrafa kowane nau'in tsarin fayil a cikin faifan diski na gida.
  2. Babu buƙatar sake kunna tsarin bayan rabuwa ta amfani da fdisk.

  1. Ƙirƙiri Tsararren Ma'ajiya Mai Tsari ta amfani da iSCSI Target - Part 1
  2. Ƙirƙiri LUN ta amfani da LVM a cikin Target Server - Part 2

  1. Tsarin Aiki - Sakin CentOS 6.5 (Na ƙarshe)
  2. iSCSI Target IP - 192.168.0.50
  3. Ana amfani da tashar jiragen ruwa: TCP 3260

Gargaɗi: Kada a taɓa dakatar da sabis ɗin yayin da LUNs ke Haɗawa a cikin injunan Client (Mafarawa).

Saitin Abokin Ciniki na Ƙaddamarwa

1. A gefen Abokin ciniki, muna buƙatar shigar da kunshin ''iSCSI-initiator-utils', bincika fakitin ta amfani da umarni mai zuwa.

# yum search iscsi
============================= N/S Matched: iscsi ================================
iscsi-initiator-utils.x86_64 : iSCSI daemon and utility programs
iscsi-initiator-utils-devel.x86_64 : Development files for iscsi-initiator-utils

2. Da zarar kun gano kunshin, kawai shigar da kunshin mai farawa ta amfani da yum umurnin kamar yadda aka nuna.

# yum install iscsi-initiator-utils.x86_64

3. Bayan shigar da kunshin, muna buƙatar gano rabo daga Sabar Target. Gefen abokin ciniki yana ba da umarni kaɗan don tunawa, don haka za mu iya amfani da shafin mutum don samun jerin umarnin da ake buƙata don gudana.

# man iscsiadm

4. Latsa SHIFT+G don Kewaya zuwa Ƙasan shafin mutumin kuma gungurawa kaɗan sama don samun umarnin misalin shiga. Muna buƙatar musanya adireshin adireshin mu na Sabar sabar IP a cikin umarnin da ke ƙasa Gano Target.

# iscsiadm --mode discoverydb --type sendtargets --portal 192.168.0.200 --discover

5. A nan mun sami ingantaccen suna iSCSI (iqn) daga aiwatar da umarni na sama.

192.168.0.200:3260,1 iqn.2014-07.com.tecmint:tgt1

6. Don shiga yi amfani da umarnin da ke ƙasa don haɗa LUN zuwa Tsarin mu na gida, wannan zai inganta tare da sabar da aka yi niyya kuma ya ba mu damar shiga cikin LUN.

# iscsiadm --mode node --targetname iqn.2014-07.com.tecmint:tgt1 --portal 192.168.0.200:3260 --login

Lura: Yi amfani da umarnin shiga kuma maye gurbin shiga tare da fita a ƙarshen umarni.

# iscsiadm --mode node --targetname iqn.2014-07.com.tecmint:tgt1 --portal 192.168.0.200:3260 --logout

7. Bayan shiga cikin LUN, jera bayanan Node ta amfani da shi.

# iscsiadm --mode node

8. Nuna duk bayanan wani kumburi na musamman.

# iscsiadm --mode node --targetname iqn.2014-07.com.tecmint:tgt1 --portal 192.168.0.200:3260

9. Sai ka jera tuƙi ta amfani da, fdisk zai jera kowane ingantattun diski.

# fdisk -l /dev/sda

10. Run fdisk don ƙirƙirar sabon bangare.

# fdisk -cu /dev/sda

Lura: Bayan Ƙirƙirar Rarraba ta amfani da fdisk, ba ma buƙatar sake yin aiki, kamar yadda muka saba yi a cikin tsarinmu na gida, Saboda wannan ma'ajin da aka raba na nesa ne wanda aka saka a cikin gida.

11. Ka tsara sabon ɓangaren da aka ƙirƙira.

# mkfs.ext4 /dev/sda1

12. Ƙirƙiri Directory kuma a ɗaga ɓangaren da aka tsara.

# mkdir /mnt/iscsi_share
# mount /dev/sda1 /mnt/iscsi_share/
# ls -l /mnt/iscsi_share/

13. Lissafi Matsalolin Dutsen.

 
# df -Th

  1. -T - Yana buga nau'ikan tsarin fayiloli.
  2. -h - Yana bugawa a sigar mutum mai iya karantawa misali: Megabyte ko Gigabyte.

14. Idan muna buƙatar hawan Drive ɗin dindindin yi amfani da shigarwar fstab.

# vim /etc/fstab

15.A saka Shigar mai zuwa a fstab.

/dev/sda1  /mnt/iscsi_share/   ext4    defaults,_netdev   0 0

Lura: Yi amfani da _netdev a fstab, saboda wannan na'urar hanyar sadarwa ce.

16. A ƙarshe duba ko shigar fstab ɗinmu yana da wani kuskure.

# mount -av

  1. -a - duk wurin hawan dutse
  2. -v - Verbose

Mun Kammala daidaitawar gefen abokin cinikinmu cikin nasara. Fara amfani da tuƙi yayin da muke amfani da faifan tsarin mu na gida.
