Hello everyone,

so I had an m.2 drive with root and lv data on it. once I ran out of space I put a 1tb ssd in my server and added the ssd as my data drive. all my vm's and ct's are transferred over and working fine. I went into datacenter storage and removed the old data lvm not realizing that only removed it from the ui.

lvdisplay shows the partition as data in group pve. but I cant remove it. lvremove just says volume group data cant be found. I don't want to remove the group pve since it was root and all the other things.

sda is the drive but data and root just show up as sda3 so I can't remove that.

I want to remove the old data and resize root to use all the space.

what am I doing wrong??
 
Thanks for the reply!
this is what im getting.

sda3 data 148.36gb is what I want to remove, dataone is the new 1tb ssd that all the vms and cts were moved to.

One missing piece - is the exact command you are trying to run and the exact error message you are getting back.
Are you using correct arguments when trying to remove the volume? Take a look at one of many tutorials online, ie:
https://www.thegeekdiary.com/lvremove-command-examples-in-linux/
note the path provided:
Code: 
lvremove vg0/myvol

P.S. I should have been clearer - use the CODE tags, they make the posts more readable.

I hope thats better, this is the command I used followed by the error
root@pve:~# lvremove data
Volume group "data" not found
Cannot process volume group data

root@pve:/dev/pve# ls
root swap

there is no data folder/partition

101 stuff I'm sure. I feel stupid now :/
