Hi all,
I have strange problem with my persistent names applied to iscsi
disks. I have configured an udev rule to assign static iscsi disk
names:
KERNEL=="sd[a-z]", SUBSYSTEM=="block", PROGRAM="/sbin/scsi_id
--whitelisted --replace-whitespace --device=/dev/$name",
RESULT=="1iTGTDSK9a2c73ce654d0ca6", NAME="iscsi/sda"
KERNEL=="sd[a-z][0-9]*", SUBSYSTEM=="block", PROGRAM="/sbin/scsi_id
--whitelisted --replace-whitespace --device=/dev/$name",
RESULT=="1iTGTDSK9a2c73ce654d0ca6", NAME="iscsi/sda%n"
When udev starts, it seems it works:
[root@cossrv01 rules.d]# ls -la /dev/iscsi/sda
brw-rw---- 1 root disk 8, 16 Mar 12 11:42 /dev/iscsi/sda
After this, I try to create a lvm volume:
[root@cossrv01 rules.d]# pvcreate /dev/iscsi/sda
... and works. But:
[root@cossrv01 rules.d]# pvdisplay
--- Physical volume ---
PV Name /dev/sdb
VG Name cmdata
PV Size 64.00 GiB / not usable 4.00 MiB
Allocatable yes
PE Size 4.00 MiB
Total PE 16382
Free PE 12542
Allocated PE 3840
PV UUID rSuu5T-VtRl-ffDd-5Vtm-CBhS-UffO-sFgCRX
Why? Why pvdisplay doesn't shows /dev/iscsi/sda instead of /dev/sdb??
It is a big problem when multiple iscsi disks are assigned in aleatory
form ... and with CentOS 5.x this procedure works out of the box ...
(with RHEL6.x doesn't works neither, but it works with RHEL5.x).
Thanks.
