Hi all, i’ve ereditated an UCS@school server with UCS 4.4.8 and i’ve to upgrade to lastest version to migrate configuration nto another UCS instance on different Hypervisor (VMware) (it’s the fisrt step to dismit an old hardware). The problem is that my /var directory haven’t enough free space.
here the situation:
lsblk

i’ve added 10G on /dev/vdd virtual disk but now i’ve to resize partition on server without data loss… but i don’t know how to do it
Please help
This works with parted
Short:
unit s
print free
resizepart 2 125829119s
resizepart 5 125829119s
print free
quit
Section- and Partitionnumber have to be changed.

If /dev/vdd1 is the last partition on /dev/vdd you could do something like this:
sudo apt install cloud-guest-utils
sudo growpart /dev/vdd 1
sudo resize2fs /dev/vdd1
These steps can be performed online (ie. not shutting down the server), a subsequent restart is not required.
That’s how I do and did increase storage size of our UCS servers hosted on our Proxmox servers.

thanks so much,
i tried the procedure and this is results:
root@srv030:/# growpart /dev/vdd 1
CHANGED: partition=1 start=2048 old: size=67106783 end=67108831 new: size=88078303,end=88080351
root@srv030:/# resize2fs /dev/vdd1
resize2fs 1.43.4 (31-Jan-2017)
resize2fs: Valore magic non corretto nel super-blocco nell'aprire /dev/vdd1
Impossibile trovare un valido super-blocco per il file system.

seems that’s partially worked but the free space on /var doesn’t change… may i’ve to reboot the server?
Please post the output from these commands:
LANG=C.UTF-8 fdisk -l /dev/vdd
LANG=C.UTF-8 df -h /var
(LANG=C.UTF-8) forces this output only to be in English, makes it easier to help 
From your output it looks like the superblock for /dev/vdd1 went missing. With ext4 as filesystem this should not be that much of a problem since ext4 stores multiple copies of the superblock.
