To verify that /root is located on the iSCSI target, do the following:
Reboot your partition and log in.
Display the mount list, filtered by grep. For example,
grep ′ / ′ /proc/mounts
The mount list, filtered by grep, is displayed. For example,
rootfs / rootfs rw 0 0 /dev/sdb5 / ext3 rw,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered 0 0
List disk drive partitions with labels. For example,
ls -l /dev/disk/by-label | grep sd5
Verify that ISCROOT points to the device listed in the grep filter output.
Using the example mount list in step 2, ISCROOT should be pointing to sdb5, matching the device “/dev/sdb5” listed on the second line of the grep filter output.
