Ubuntu Help - Boot Problem #N00b

[RogerBrownTDL]

@Sebastian-Roth So obviously as a Linux noob, I know very little… I’m purely (I know, insert puke emoji here) a Windows Sysadmin. If I understand it correctly the way i’ve got it setup is like having a single big C:\ and all i’m wanting to do is get the entire fog server to see it all rather than just a partition of it… If I follow that command
“lvextend --extents +100%FREE ubuntu-vg/ubuntu-lv --resizefs”
Will it do that so that the full 500gb would be visible and the images stored remain intact?

Yes! Although I am not a 100% sure the filesystem resize (to full size) will work while the system is running. Should work but I can’t promise you it will. As well just for safety reasons I always suggest for people to take a backup copy before doing these kind of operations on a production server. Should be really easy taking a snapshot in Hyper-V before going ahead.

The other option I was talking about would be like adding a D:\ drive and moving all the images to that new partition. As I said it’s wise on the one hand so images can’t fill up your important C:\ drive (with the database on it) but on the other side you waste free space on C:…

@Sebastian-Roth further info print i’ve got if this makes more sense:
root@tie-fogdeploy-01:~# sudo parted /dev/sda unit MiB print
Model: Msft Virtual Disk (scsi)
Disk /dev/sda: 512000MiB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags:

Number Start End Size File system Name Flags
1 1.00MiB 2.00MiB 1.00MiB bios_grub
2 2.00MiB 2050MiB 2048MiB ext4
3 2050MiB 511999MiB 509949MiB

If the system isnt running, surely I wouldnt be able to do anything, so it needs to be online?

Well, you can boot into a Live Linux ISO (Ubuntu or many others) to get to a command shell and do such things with the OS on disk not running. But I think you are fine doing it live after taking a snapshot backup.

@Sebastian-Roth Thanks my friend, snapshot taken in hyper-v and command run… Stupid Q now. How do I check if it’s worked

[Sebastian Roth]

@RogerBrownTDL Reboot and take a look at the disk space with df -h.

i’m guessing /dev/mapper/ubuntu–vg-ubuntu–lv 490G 86G 384G 19% / means its worked?

Nice, that looks great.

Marking as fixed.

@Sebastian-Roth Thanks friend Legendary!

@Sebastian-Roth I didn’t know about the 100% option - I like that!
