I'm on WHM 11.30.5 (build 3)


Did the "Format/Mount a new drive" function in cpanel but although we received the PROCESS COMPLETED message at the end, the newly formatted drive could not be mounted.

Mount point /home2

fdisk -l output:

# /sbin/fdisk -l


Disk /dev/sda: 251.0 GB, 251059544064 bytes
255 heads, 63 sectors/track, 30522 cylinders

/etc/fstab entry:
/dev/sdb1 /home2 ext3 defaults,usrquota 1 2


Attempts to mount manually result in:
# mount -t ext3 /dev/sdb1 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so



# dmesg | tail

So at this point i believe the 2nd drive did not get formatted properly. Here is the displayed log during the format/mount operation:

p primary partition (1-4)

Turning Quotas on for the new drive

Quotas are now on

Can someone please help and tell me how to correct this?


Thank you!

Hello,

Run the following commands as root via SSH.

#mkfs.ext3 /dev/sdb1 - this will format sdb1 with ext3 FS

When it completes, try to mount the drive using

mount /dev/sdb1 /mnt

Post the results back here!

Thank you,
Nibin.

Hello,

If your OS supports ext4, I recoemmend you to try ext4 instead.

#mkfs.ext4 /dev/sdb1
#tune2fs -m 0 /dev/sdb1 - this will ensure the reserved space is et to 0%
#mount /dev/sdb1 /mnt

Thank you,
Nibin.
