Turbo Installation
apt-get install open-iscsi
Edit /etc/iscsi/iscsid.conf
... node.startup = automatic ...
derefter en restart :
/etc/init.d/open-iscsi restart
Discover LUN:
root@testbox:~# iscsiadm -m discovery -t st -p 192.168.8.31
Output : 192.168.8.31:3260,1 iqn.2004-04.com.qnap:ts-239:iscsi.qnap1.8d8976
iscsiadm -m node
Output : 192.168.8.31:3260,1 iqn.2004-04.com.qnap:ts-239:iscsi.qnap1.8d8976
... vi springer lige over CHAP ...
Nå, opret forbindelse :
iscsiadm -m node --targetname "iqn.2004-04.com.qnap:ts-239:iscsi.qnap1.8d8976" --portal "192.168.8.31:3260" --login
Nu skulle disken kunne findes med
fdisk -l
Man kan detache med --logout :
iscsiadm -m node --targetname "iqn.2004-04.com.qnap:ts-239:iscsi.qnap1.8d8976" --portal "192.168.8.31:3260" --logout
Over 2TB
Ikke kun et iSCSI issue, men Linux kræver GPT for at kommer over 2TB diske:
apt-get install gdisk gdisk /dev/sdb
Kommandoer:
b back up GPT data to a file c change a partition's name d delete a partition i show detailed information on a partition l list known partition types n add a new partition o create a new empty GUID partition table (GPT) p print the partition table q quit without saving changes r recovery and transformation options (experts only) s sort partitions t change a partition's type code v verify disk w write table to disk and exit x extra functionality (experts only)
Så, o, n og w.
