Adjusting/Rescanning iScsi drive size
I've been having trouble getting my server to automatically adjust the size of a iScsi drive is mounted:
# The size reflected is 39G, but it should be 30G
[ffallateuf@ps-dev-nfs ~]$ df -kh | grep ps-dev-nfs
ps-dev-nfs:/mnt/filestore
39G 2.8G 34G 8% /mnt/filestore
# I unmount the drive
[root@ps-dev-nfs ~]# umount -l /mnt/filestore
[root@ps-dev-nfs ~]#
# I rescanned both interfaces
[root@ps-dev-nfs ~]# iscsiadm -m node -R -I iface0

# Then I rescan it through fsck & attempt to resize it with no success

The filesystem is already 7864320 blocks long. Nothing to do!

So apparently, when I run "fdisk", I see the correct size. But when I do "df -k", the size is wrong.
Why are both different and what can I do to adjust this?
Thank you,
Franck

I resolved this issue. Apparently, the alias I created for the iScsi drive was wrong in the /etc/fstab, so it was the wrong mount.0
