Can't make fs as big as partition

[Tomi Lehtinen]

Hello all,

I can't make file system which would be as big as partition defined for fs. I have made partitions with fdisk (see output below) and mount points.

Mount points are:

/oracle/BC1
/oracle/BC1/sapdata1
/oracle/BC1/sapdata2
.
/oracle/BC1/sapdata6

I have defined partition for /oracle/BC1 which is 1.4 Gb and partitions for /oracle/BC1/sapdataX which are 5.0-7.0 Gb each.

When mounting filesystems, I get that 1.4Gb for /oracle/BC1 (correctly) but also /oracle/BC1/sapdataX are sharing that 1.4Gb!

Here is output of 'fdisk /dev/sdb' (related to fs mentioned above):

Device Boot Start End Blocks Id System

/dev/sdb15 5217 5408 1542208+ 83 Linux

Here is /etc/fstab:

/dev/sdb9 /oracle/BC1/sapdata1 ext2 defaults 1 2
/dev/sdb10 /oracle/BC1/sapdata2 ext2 defaults 1 2
/dev/sdb11 /oracle/BC1/sapdata3 ext2 defaults 1 2
/dev/sdb12 /oracle/BC1/sapdata4 ext2 defaults 1 2
/dev/sdb13 /oracle/BC1/sapdata5 ext2 defaults 1 2
/dev/sdb14 /oracle/BC1/sapdata6 ext2 defaults 1 2
/dev/sdb15 /oracle/BC1 ext2 defaults 1 2

And, finally, here is output of df:

/dev/sdb9 1517920 60 1440752 0% /oracle/BC1/sapdata1
/dev/sdb10 1517920 60 1440752 0% /oracle/BC1/sapdata2
/dev/sdb11 1517920 60 1440752 0% /oracle/BC1/sapdata3
/dev/sdb12 1517920 60 1440752 0% /oracle/BC1/sapdata4
/dev/sdb13 1517920 60 1440752 0% /oracle/BC1/sapdata5
/dev/sdb14 1517920 60 1440752 0% /oracle/BC1/sapdata6
/dev/sdb15 1517920 60 1440752 0% /oracle/BC1

Any help would be appreciated.

Hi,

Try this:

mkdir /oracle/BC1

mount /dev/sdb15 first

make the other directories on the /dev/sdb15 partition (ie, after you mount the /oracle/BC1 directory).

then mount the rest of the partitions.

so, if you already have all the partition mounted, do:

umount -a
mount /dev/sdb15
mkdir /oracle/BC1/sapdata1
...
mount -a

should work and solved your problem.
