Disk partition and size problem

[caplam]

Hello,

I have a vm with a boot disk on lvm-local.
I have attached a second disk to the host (by uuid)
On the disk i created a lv in which i created a second disk for my guest.
The physical disk is a 937Gb
The guest disk was 282Gb
I resized it to 350Gb.

In my guest i see that:

fdisk -l

Disque /dev/sdb : 350 GiB, 375809638400 octets, 734003200 secteurs
Unités : secteur de 1 × 512 = 512 octets

/dev/sdb1     2048 591394815 591392768   282G Système de fichiers Linux

but when i want to resize the partition with parted i have that:

(parted) print free                                                      

Model: QEMU QEMU HARDDISK (scsi)

Disk /dev/sdb: 376GB

Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number  Start   End     Size    File system  Name  Flags
        17,4kB  1049kB  1031kB  Free Space
1      1049kB  303GB   303GB   ext4
         303GB   376GB   73,0GB  Free Space

what do i need to do ?
If i resize the part 1 to occupy free space i will have problems?

il faut peut etre mettre le format de ta partition dans le montage exemple: -t ext3

Finally i umounted my partition and with fdisk i destroyed and recreated it at 349G (wasn't possible at 350G).
Then i resized the fs.
the only weird thing is that parted doesn't see the right size (375G).
