Default LVM Datastore in 4.2

[anigwei]

Hi,

After deploying a new server with latest version (4.2) I've noticed that /var/lib/vz does'nt exists anymore.

Instead, it uses LVM as RAW storage for VMs.... (It created local-lvm datastore).

This is new in 4.2?

Is it better than qcow2 files into /var/lib/vz as used to be before as the default option?

Thanks!

/var/lib/vz is still here, check with:

> ls -l /var/lib/vz

every storage type has some interesting features, so there is no real better. depend on the use case.

and yes, this is new with 4.2 ISO installation.

Hi tom,

Yes, /var/lib/vz it is present but inside root partition. I usually set maxroot to 10Gb... so now /var/lib/vz is 10Gb shared with system

I'd like that Proxmox during install let the user choose whether use local-lvm or leave an entire partition to /var/lib/vz as before

Thanks!

One advantage is that you can run containers with quota an snapshot support.

Hi!

Yes, there are plenty of advantadges

But, at install time, is there any way of choose if you want "new LVM layout" or "old /var/lib/vz into EXT4 partition"?

Thanks!

Currently not. You need to reconfigure that manually.

Hi,

So I did this:

lvremove /dev/pve/data
lvcreate -l100%FREE -n datastore pve
mkfs.ext4 /dev/pve/datastore

And mount it on your fstab:

/dev/pve/datastore /mnt/datastore ext4 defaults 0 0
