Cannot add see new storage
Hi peeps,
I have just added 2 146gb disks to an existing RAID5 system running Oracle Enterprise Linux 5.4. I used Dells open manage software to rebuild the RAID which was successful although I cannot see the additional storage when I look on the system. Basically how do I get Linux to show the new storage and then add it to an existing partition. |
Does it show up in /sbin/fdisk -l ?
If so, use lvextend and resize2fs. |
I ran /sbin/fdisk -l and it does not show although if I fire up the LVM gui it shows up as an unpartioned space??
|
Have you rebooted since you added it? You can't modify the partitions of the disk the system booted off of, and expect the changes to show, without rebooting.
|
I have rebooted the box several times and the new storage will not show although I have not actually dared to changed anything on the file system yet.
Basically I have gained 272GB by adding the extra disks to the RAID and this shows in LVM but I do not know how to add this extra to the file system. Do I have to create a new mount point?? I built the server and several others but I have never had to add extra disks so am a little stuck. I am not too fussed about extending an existing partition just adding a new one which would be the size of the storage gained. This is the current fs Filesystem Size Used Avail Use% Mounted on /dev/sda7 9.5G 814M 8.2G 9% / /dev/sda11 2.0G 0 2.0G 0% /dev/shm /dev/sda10 965M 18M 898M 2% /tmp /dev/sda9 1.9G 131M 1.7G 8% /var /dev/sda8 4.8G 2.2G 2.4G 49% /usr /dev/sda6 19G 2.2G 16G 12% /home /dev/sda5 48G 23G 23G 50% /orahome /dev/sda2 236G 208G 16G 94% /oradata /dev/sda1 965M 34M 882M 4% /boot tmpfs 2.0G 0 2.0G 0% /dev/shm Cheers. |
Another check.....as you are using Dell, have you checked in the PERC's BIOS (ctrl-r during boot up) to see if the drives show up there in the RAID set?
|
How can it show in LVM but not fdisk? Can you post what you're seeing on both?

Does this help. Attatchment shows LVM screenshot

And ... can you confirm that you followed steps as outlined here: How can I add a hard drive to an existing Virtual Disk on my SAS PERC controller?
This technote is for PERC5 on Windows but the same steps apply as you are using a web interface. |

I plugged the disks in and used openmanage to rebuild the RAID which took about 14 hours. It shows up fine in openmanage but I cannot seem to access it from Linux. I thought I was being dumb but perhaps something isnt how it should be.... |
Solved
Managed to sort it out by downloading GPARTED which is a disk partition utility for Linux.
It located the elusive new storage and allowed me to create a new extended partition as I already had 4 primary partitions. Happy days.... |
