That's strange. I have no useful input, but I'm simply chiming in to state that we have much larger than 2TB iSCSI LUNs working fine, under CentOS 5.x here. I can't imagine CentOS 6.x would regress in that manner.
The only time I've seen something similar (especially the 0 byte size export) is when we have neglected to give a specific initiator access to a given LUN on the target side - the LUNs still show up, and you get a block device - but it's zero length as shown here. I don't believe it's the same issue, but just tossing it out there! I am assuming a 64bit kernel? -Phil On Sun, Dec 30, 2012 at 8:41 AM, Didenko <iru...@gmail.com> wrote: > I have Segate Blackarmor 440 4x2TB HD in raid 5 > > i create ISCSI device > 5493 GB 0 Full Access > > service iscsi start > > iscsiadm -m discovery -t st -p 192.168.0.2 > > fdisk -l no see new disk > > dmesg > > scsi5 : iSCSI Initiator over TCP/IP > scsi 5:0:0:0: Direct-Access SCST_FIO BZ 200 PQ: 0 ANSI: 5 > sd 5:0:0:0: Attached scsi generic sg1 type 0 > sd 5:0:0:0: [sdb] 0 512-byte logical blocks: (0 B/0 B) > sd 5:0:0:0: [sdb] 4096-byte physical blocks > sd 5:0:0:0: [sdb] Write Protect is off > sd 5:0:0:0: [sdb] Mode Sense: 83 00 10 08 > sd 5:0:0:0: [sdb] Write cache: enabled, read cache: enabled, supports DPO > and FUA > sd 5:0:0:0: [sdb] Attached SCSI disk > > [root@localhost ~]# sg_readcap --16 /dev/sdb > Read Capacity results: > Protection: prot_en=0, p_type=0, p_i_exponent=0 > Thin provisioning: tpe=0, tprz=0 > Last logical block address=18446744073709551615 (0xffffffffffffffff), > Number of logical blocks=0 > Logical block length=512 bytes > Logical blocks per physical block exponent=3 > Lowest aligned logical block address=0 > Hence: > Device size: 0 bytes, 0.0 MiB, 0.00 GB > > [root@localhost ~]# sg_readcap --pmi /dev/sdb > READ CAPACITY (10) indicates device capacity too large > now trying 16 byte cdb variant > Read Capacity results: > Protection: prot_en=0, p_type=0, p_i_exponent=0 > Thin provisioning: tpe=0, tprz=0 > PMI mode: given lba=0x0, last lba before delay=0xffffffffffffffff > Logical block length=512 bytes > Logical blocks per physical block exponent=3 > Lowest aligned logical block address=0 > any help ? > > If i creat iscsi device little 2TB .. i can join in Centos ..not any > problem > iscsi initiator last version > > -- > You received this message because you are subscribed to the Google Groups > "open-iscsi" group. > To view this discussion on the web visit > https://groups.google.com/d/msg/open-iscsi/-/GFxIhSKU2WMJ. > To post to this group, send email to open-iscsi@googlegroups.com. > To unsubscribe from this group, send email to > open-iscsi+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/open-iscsi?hl=en. > -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
