/dev/pve/data entry not in fstab after install proxmox 4.4

[hronny]

Hello. Currently i just reinstall the proxmox host (ISO: Proxmox VE 4.4 (build eb2d6f1e-2). After the installation I noticed that the hard disk size is only 95 GB instead 2.7 TB. After a check I saw that the /dev/pve/data partition is not in the /etc/fstab file. Therefore, the system is unusable. Whats wrong here?

This could be because of the thin LVM configuration and not really a bug.
Can you check the storage item in the web GUI.

This host is a part of a four node cluster. After i connected this node to the cluster and try to migrate the vm from other node to this, the operation fails because out of space. All my virtual machines was created on this machine on local storage. Before reinstall i moved all machines to another node and now back with web GUI.

since 4.2 we format only a small portion of the harddisk as a filesystem (just for root), and leave the most space for lvm-thin (which enables snapshots for container for example)

i guess you have a cluster with nodes installed from <4.2

so you can one of two things for example:

1. add a storage in the webgui for this lvm-thin, which is restricted to the one node installed with 4.4
e.g.:

lvmthin: local-lvm
thinpoold data
vgname pve
content rootdir,images
nodes YOUR4.4NODE

2. create a filesystem in or instead of the lvmthin lv
like it is described here:

Thank you for your message. You are right, my cluster has still been created with the old version.
The first variant has an additional problem which I could not solve. When migrating, you can not specify the target storage and still use "local". The Storagename is also used when restoring from a backup. That's why I chose the second option.

lvremove  /dev/pve/data
lvcreate -n vz -L 370G pve
mkfs.ext4 /dev/pve/vz
mount --all

After this i added one line in the fstab for /var/lib/vz. I think my problem is solved. But I also think that there is a reason that some proxmox versions a new storage technology is used. Maybe I find it still out how it works.

If I add LVMthin storage from GUI to the 4.4 node. where would I find the actual files using ssh?
