Troubles expanding file system.
by Jeff Boyce 01 Sep '21

01 Sep '21

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 … [View More]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 [View Less]

systemd | Requires statement with an instantiated service
by Leon Fauster 01 Sep '21

01 Sep '21

Maybe the work day is already to long. I can not find a solution for following requirement. How to apply a "Requires" with an instantiated service. Example: a@.service b.service a@.service is started as a(a)host1.service and b.service must be started after a(a)host1.service but the unit will be differently parameterized (depended of the region). So I want to generalize the requires statement. My dropin file in ./b.service.d/dep.conf looks like [Unit] Requires="a(a)*.service" This just … [View More]

Re: [CentOS] Application migration
by Mark Woolfson 01 Sep '21

01 Sep '21

Hello, I have some data analysis applications running on CentOS 6.4 and 6.6. Due to these CentOS variants not being supported on the Intel Ice Lake server platform I have to migrate them. The minimum CentOS variant which works on the Ice Lake is 7.4. Please can you give me an idea of the migration complexity of moving the applications from 6.4/6.6 to 7.4 or any variant of 7.
