Re: Partition mounting under RHEL4

What does 'fdisk -l /dev/sda' return? How about for sdb and sdc? Did you create partitions (/dev/sda1, /dev/sdb1, /dev/sdc1)?

If you did create partitions, what does 'e2label /dev/sda1' return? If not, how about 'e2label /dev/sda'?

I am having a problem with a new install of Red Hat Enterprise Linux 4.
RHEL4 is required in this particular work instance.
This is a SuperMicro 1U server with the 2010S ZCR card option for the two main SCSI drives. I have a SCSI RAID container on one of the SCSI chanels and have a Fibre Channel Raid enclosure (EonStore) and an LSI FC919X Fibre Channel Card.

I have the following entries in my /etc/fstab:

#/dev/sda /raid/fc0 ext3 defaults,usrquota 1 2
#/dev/sdb /raid/fc1 ext3 defaults,usrquota 1 2
#/dev/sdc /raid/fc2 ext3 defaults,usrquota 1 2

#LABEL=FCraid0 /raid/fc0 ext3 defaults,usrquota 1 2
#LABEL=FCraid1 /raid/fc1 ext3 defaults,usrquota 1 2
#LABEL=FCraid2 /raid/fc2 ext3 defaults,usrquota 1 2


If I un-comment the /dev/sd* entries and try to mount the partitions I get an error about a bad superblock.
If I un-comment the /dev/sd* entries and restart the server I get an error about a bad superblock when it tries to mount the partitions.
If I un-comment the LABEL=FCraid* entries and try to mount the partitions they mount just fine but Apache does not seem to recognize directories on these mount points.
( Apache is a different problem altogether, I think, but I though it worth mentioning as a possible symptom of the problem.)
If I un-comment the LABEL=FCraid* entries and restart the server I get an error that it cannot find partitions with those labels.

Originally /dev/sdb and /dev/sdc were formatted as xfs when the labels were made. I reformatted them to ext3 when I found that Red Hat completely dropped xfs in RHEL4 but I did not change the label when I did the reformat.

These are 1.8TB partitions and about half full of data so I need to be very careful not to do anything that will damage the integrity of the data.

When using Red Hat 7.3 e LABEL=FCraid* entries in /etc/fstab work just fine.

Any suggestions on how I can get this to work?

Bruce
