Hi
I am not sure that I have a full and complete understanding here.
I installed CentOS 5 in early April and then upgraded the kernel to
2.16.18-8.1.3.el5xen a few days ago. This is when I noticed that the two
USB discs had improper and irregular names in my file system.
In installing CentOS 5 I noticed that I could label (not sure that is
the correct word) these two USB devices which are generally permanently
mounted. I liked this idea as it allowed me to have a better backup
process as well as more natural path to my music digitization project.
With the kernel upgrade the pointings became erratic. This is almost
certainly due to the level of system work I was attempting to do in
bringing on-line lightscribe technology and video/DVD technology as well
as maintaining my science/engineering computing base.
It was suggested that I review the man pages for fstab, mount and
e2label. This I have done and I hope I understand. But firstly it is
necessary to state that the file systems on these USB drives is VFAT and
not ext2 or ext3. Why so, because I regularly need to carry, move, the
records and the backup information to family windows machines. I guess
that there are other methods that I should now consider and I am willing
to do that if it is will generate a more stable system for myself.
What I find is as follows:
The original fstab which correctly points to the file system
[root@currawong etc]# more fstab
LABEL=/ / ext3 defaults 1 1
/dev/sdb1 /backup vfat defaults 0 0
LABEL=/boot /boot ext3 defaults 1 2
LABEL=/data /data ext3 defaults 1 2
LABEL=/data21 /data2 ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
LABEL=/home /home ext3 defaults 1 2
LABEL=/opt /opt ext3 defaults 1 2
proc /proc proc defaults 0 0
/dev/sda1 /records vfat defaults 0 0
sysfs /sys sysfs defaults 0 0
LABEL=/tmp1 /tmp ext3 defaults 1 2
LABEL=/usr/local /usr/local ext3 defaults 1 2
LABEL=SWAP-hda3 swap swap defaults 0 0
[root@currawong etc]# mount -a
If I change fstab to the following
LABEL=/ / ext3 defaults 1 1
LABEL=Backup /backup vfat defaults 0 0
LABEL=/boot /boot ext3 defaults 1 2
LABEL=/data /data ext3 defaults 1 2
LABEL=/data21 /data2 ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
LABEL=/home /home ext3 defaults 1 2
LABEL=/opt /opt ext3 defaults 1 2
proc /proc proc defaults 0 0
LABEL=Records /records vfat defaults 0 0
sysfs /sys sysfs defaults 0 0
LABEL=/tmp1 /tmp ext3 defaults 1 2
LABEL=/usr/local /usr/local ext3 defaults 1 2
LABEL=SWAP-hda3 swap swap defaults 0 0
and then try to mount I get the following errors.
[root@currawong etc]# mount -a
mount: special device LABEL=Backup does not exist
mount: special device LABEL=Records does not exist
Clearly it is the label that is not correct or being picked up. I have
tried quite a few other combinations,
lower case, with and without the / all of which give the same problem.
So is the problem due to the VFAT file systems, a miss understanding on
my part, or something else.
I would appreciate understanding the problem from others
cheers Peter
