We've resized an iSCSI based LUN and are trying to resize the associated physical volume. I've re-scanned the iscsi bus, resized the multipath device (mpath0), but cant resize the physical volume:
1. Multipath device is 1.5T
[root@dcsorap02 ~]# multipath -ll mpath0
mpath0 (368b7b24ca523e05052f714f2a97ce369) dm-7 EQLOGIC,100E-00
[size=1.5T][features=1 queue_if_no_path][hwhandler=0][rw]
\_ round-robin 0 [prio=2][active]
\_ 8:0:0:0 sdb 8:16 [active][ready]
\_ 10:0:0:0 sde 8:64 [active][ready]
-
2. Physical volume is 1TB
[root@dcsorap02 ~]# pvdisplay /dev/dm-7
--- Physical volume ---
PV Name /dev/dm-7
VG Name vgoradata01
PV Size 1.00 TB / not usable 2.00 MB
Allocatable yes
PE Size (KByte) 4096
Total PE 262147
Free PE 3
Allocated PE 262144
PV UUID lkAYd6-EXy9-VBGh-B4XZ-jte1-EgHY-9DIc3N
3. Cant resize the PV
[root@dcsorap02 ~]# pvresize /dev/dm-7
Unable to find "/dev/dm-7" in volume group "vgoradata01"
0 physical volume(s) resized / 1 physical volume(s) not resized
Am I missing something?
Thanks,
Fraze
