MSA1500cs does not update extend logical drive


Hello,

Im having problems with msa1500cs. The problem is that i need to extend logical drive size.
first: I expand the array without problems. Later I extend the logical drive size. After finish the process to extend the logical drive, i can see the new size in the ACU utility, but when i umount and mount the partition to see the new size, it still have the old size. I dont know whats going on. While ACU utility says a new size, my operating system says another on. The question is: how can i update my logical drive in the operating system to update the new size.

Im running Red Hat EL 5

Thanks

Cristhian

Hello,

only the disk, that you see under RHEL5 is bigger, not the overlaying filesystem. You should extend you filesystem too.

Start fdisk an take a look at the free space at the end of the disk.

Kind regards,

Hello Cristhian,

no, you can't use fdisk to do this. You could add a new partition on that extended disk, but you can't enlarge a filesystem with fdisk.

Which filesystem do you use with RHEL? If you're using ext2/ext3 you can use resize2fs. Take a look at the manpage: man 8 resize2fs. If you're using ReiserFS, take a look at the manpage of resize_reiserfs.

I've done this many times, without problems. But you should have a valid backup. :) And dismount the partition before you extend it.

Kind regards,
Patrick
