change directory size

[fropa]

I installed Promxmox 5.1-38 version. I have 2T hard drive. After installation it has 90G local (PATH /var/lib/vz ) and the rest of hard is local-lvm (LVM-thin). Now I want to increase local up to 300G and leave the rest for local-lvm.

I do the following steps :
#lvremove pve/data
#lvresize -l 50000 pve/root
#lvcreate -L 300G -n data pve
#lvconvert --type thin-pool pve/data
#lvextend -l +100%FREE pve/root

After that everything is ok in lvs command :
root@Proxmox:~# lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
data pve twi-a-tz-- 299.80g 0.00 1.22
root pve -wi-ao---- 1.52t
swap pve -wi-ao---- 8.00g

But it's not ok from web. It changes only local-lvm size not local directory, that is still 90G.

How can I do that ?

You need to resize the file system on /pve/root using resize2fs

As you've not used the "-r" option for lvresize, which resize the volume AND recursively the underlying filesystem, you know need to run resize2fs /dev/mapper/pve-data

Tried, get error :

root@Proxmox:~# resize2fs /dev/mapper/pve-data
resize2fs 1.43.4 (31-Jan-2017)
resize2fs: Bad magic number in super-block while trying to open /dev/mapper/pve-data
Couldn't find valid filesystem superblock.

On what device is your /var/lib/vz mounted on ? My PVE have been upgraded since 4.0 so it may be a different device naming on fresh install.

Please do not touch pve-data - The file system we talk about is on /dev/mapper/pve-root

It's not how I've understood the "problem":

I installed Promxmox 5.1-38 version. I have 2T hard drive. After installation it has 90G local (PATH /var/lib/vz ) [...] But it's not ok from web. It changes only local-lvm size not local directory, that is still 90G.​

For me, he wants to increase the "local" storage from 90 to 300GB, which is mounted on /var/lib/vz (pve-data) and not / (pve-root).

you run an old version ...

5.1-36 here, but upgraded several times from 4.0.

yes, new versions use other fs layout

I've just installed a fresh 5.1 to check and see the differences
