Greetings -
I have tried posting this four times now, from two different email addresses (on the 25th, 27th, 30th, and 31st) and it never appeared. I don't see it in the archives, so it appears to be getting dropped in transition for some reason. I am not getting messages from the email system saying it is undeliverable, or is bounced; I am sending as plain text, not HTML, I stripped off my signature. If this makes it through, someone please give me a clue why the others might not have. But that is not as important as the real issue that I am trying to get addressed below. Thanks for any assistance.
I have a Dell PowerEdge server with a CentOS KVM host (Earth) with one CentOS guest (Sequoia) that I am trying to expand the partition and filesystem on. I have LVM logical volumes on the host system (Earth), which are used as devices/partitions on the guest system (Sequoia). In this particular situation I have successfully extended the logical volume (lv_SeqEco) on Earth from 500GB to 700GB.
1. Checking the disk information (lsblk) on Earth shows that the logical volume (lv_SeqEco) is now listed as 700GB.
2. Checking disk information (lsblk) on Sequoia shows that the disk /dev/vde is still listed as 500GB, and partition /dev/vde1 where the mount point /ecosystem is located is also listed as 500GB.
3. I had tried using the resize2fs command to expand the filesystem on /dev/vde1, but it returned with the result that there was nothing to do. Which makes sense now after I checked the disk information, since /dev/vde on Sequoia has not increased from 500GB to 700GB.
4. On previous occasions when I have done this task, I would just start GParted on Sequoia and use the GUI to expand the partition and filesystem. A real quick and simple solution.
5. The problem I have now is that the VGA adapter on my server has died and I have no graphical output to the attached monitor, nor to the iDrac console display. So I am stuck doing this entirely by the command line while logged into the system remotely.
6. I suspect that I need to rescan the devices on Sequoia so that it recognizes the increased space that has been allocated from the extended the logical volume. But when I did that (command below) it came back with a no such file or directory.
echo 1 > /sys/class/block/vde1/device/rescan
7. This server is being retired in the next few months, but I need this additional space prior to migrating to the new system. Can someone give me some guidance on what I am missing in this sequence?
Let me know if I haven't been clear enough in the explanation of my systems and objective. Thanks.
Jeff
