I found instructions that resulted in failure to replace the bad drive. The 'bad' drive still works but the directions to add a new drive did not work. I shutdown the computer and unplugged the 'bad' drive.

On rebooting I ran: vgreduce --removemissing --force vg00

I was not able to mount the lvm afterwards.

I have looked for instructions on deleting the lvm and creating a new lvm and I have not been able to recover.

I am running Fedora 31.

pvs displays: at this point I have not added /dev/sda1 to the volume group.

PV VG Fmt Attr PSize PFree /dev/sda1 lvm2 --- 931.51g 931.51g # this is the new drive /dev/sdb1 vg00 lvm2 a-- <465.76g 0 # this is the bad drive /dev/sdc1 vg00 lvm2 a-- <465.76g 0 /dev/sdd1 vg00 lvm2 a-- <3.64t 0

I created a new lvm.

lvs displays:

LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert LVM vg00 -wi-a----- <4.55t

using the command:

mount /dev/mapper/vg00-LVM /tv

displays this error:

mount: /tv: wrong fs type, bad option, bad superblock on /dev/mapper/vg00-LVM, missing codepage or helper program, or other error.

I do not know what the next step should be.

If I have left anything out please let me know.

Thanks for any assist,

David
