How do I expand/extend VM partion (Xen, Ubuntu)
-
@guyinpv The good news is that it's on an LVM, so expanding it is quite easy. I'd normally add another virtual drive as I find it easier to add a physical volume into an existing volume group. I know a guy who did a presentation on LVM recently.
pvresize /dev/xvda5 resize2fs /dev/mapper/seafile--vg-rootYou might have to do the resize2fs after booting into recovery mode, can't always resize a mounted partition. Should be rare now, but you never quite know.

So here is the output of those commands:Physical volume "/dev/xvda5" changed 1 physical volue(s) resized / 0 physical volume(s) not resized ... resize2fs 1.42.9 (4-Feb-2014) The filesystem is already 3832832 blocks long. Nothing to do!But if I type
df -hthose 35GB or so aren't appearing anywhere. -

echo 1 > /sys/block/xvda/rescanIf that doesn't work, then it get's slightly more complicated knowing where to look in /sys.

not the answer you are seacrhing for. anyway while this is really rude, if I have space, I prefer to create a new disk and use stuff like a live distro to move the system to the new disk, reinstall grub and go...

Yeah, I very much prefer adding another drive myself. But you just don't have to move anything with LVM, just extend the volume group.

I tend to not use LVM in VMs, just because mine are so small that it is realy simple to cp -va /* from live and then chroot and reinstall grub.

I don't like reinstalling grub when I don't have to. And I never have to move/copy anything. Might be doing yourself a disservice in not learning logical volume management (weather that's LVM, btrfs, or zfs.)

I don't usually extend the existing group. I have a VG for the OS and a VG for the data. Then I can just unattach/reattach the disk if I need to rebuild.

Easy button.....blast the VM out of existence. Who has time to fight this crap?
I'll rebuild my Seafile system from the start but I just want to set it up better. Probably run on CentOS7 instead of Ubuntu, especially Ubuntu 14.
Since this is a file store, some other arrangement of VDs would probably be appropriate to make sure I have a backup of our data. That is, instead of running everything off a single large disk.

It is not about not learning LVM: I use it into the host, for the very purpouse of have flaxibility in storage config/expansion.
It is about having really simple containers for my apps. -
XenCenter released for Linux? Nice, when did that happen?

Containerization a new technology? I had it available in IRIX back in the 1990s, how could it be new?

@scottalanmiller It's called XO.

it is not the tech is how people invest in knowledge. here is just windows server 2012+vmware. P.E.R.I.O.D.
want more knowledge? pass to enterprise level supply chains.
really, even yesterday I've talked with e potential new service provider: it was a microsoft shop. linux? naaa. unix? in the '80... -
@matteo-nunziati of course when I say windows I mean GUI not powershell. hell, the sysadmin has gone a bit nervous when he seen my server core VM and my hyper-v server install. he asked: are you sure you do not want a gui?
answer: yes please, put a cream topping on it, also!
-
of course it is a matter of market: if you move in the ICT market your providers are more skilled. but if you work in manufacturing with the S of SMB, what you get is this. It is not supply chain segmentation: it is your employer mindset which casts you to certain type of providers and you have to manage to change the mindset (good luck) and deal with daily issues to be solved.
as example: did you see my VoIP incident?

XO is only on 5.7. So that can't be it.

Not sure what you mean here.
TBH, I think @guyinpv meant XS when he said XC.
