How to expand drive space on RHEL 4?
What is the process to properly go about doing this?
Some further information:
I am using LVM for the current setup with an ext2 filesystem.
Thanks in advance

Re: How to expand drive space on RHEL 4?
If your enllarged RAID system is say /dev/sdb1 and it is used as a physical volume by an LVM VG - then pvresize should do the trick.
Prior though -- make sure the OS recognizes /dev/sdb is at its correct enlarged size (do a scsi scan and check via fdisk)
Cheers!

Re: How to expand drive space on RHEL 4?
How do I do a rescan? (fdisk doesn't recognize the extra space)

Re: How to expand drive space on RHEL 4?
if the disk size is increased.. then fdisk to enlarge the partition and do the pvresize thing.
Caveat! Make sure pvresize is supported in RHEL 4... man pvresize

It didn't find the additional space.
Am I going to have to reboot?

Re: How to expand drive space on RHEL 4?
Or RHEL 4 does not support online disk/lun ersizing or the Smart Array dose not imediately communicate the geometry chanegs to the OS.
The procedure works with SAN Luns though and on RHEL 5.X

Re: How to expand drive space on RHEL 4?
I did not actually catch your post mortem comment:
"I used Webmin to create the 'Linux LVM' partition "
That to me indicates you did not opt to use fdisk to extend the partition and use pvresize to enlarge the underlying existing PV... Glad it works though.
Also, that SCSI scan -- it really should have worked. maybe your RAID controller is not host0? Or maybe the RAID controller is not on the path I posted?
EIther way -- kool that it works...

Re: How to expand drive space on RHEL 4?
Turns out that it didn't work. I would still have to do some other tasks to add the group.
I decided to try pvresize instead, but first I need help in how to use fdisk to expand the partition.
>>Also, that SCSI scan -- it really should have worked. maybe your RAID controller is not host0? Or maybe the RAID controller is not on the path I posted?
I have the volume set up on a SmartArray 5300 that I believe is located at host1. Either way it didn't work there either.
