undo LVM

[Michel Racic]

Hi Luis

Yes I know how important backups are and I gave most of my urgent data
backed up on various places but this 1TB disc is my main backup and My other
disc crashed...

I'm too pussy to just try that out so I first have to get a new 1TB disc and
dd (mirror) the disc so I can try this out on the mirror disc...

I don't think that vgreduce will work but i try as soon I have the mirror
disc

Thx and regards
Michel

Hi, Michel

So, I would try

$ sudo vgreduce data /dev/sdb1
My only concerns is that sdb1 is the only pv of the volume.

Will not run the pvmove, that may mess your data

Then I'll try to mount it and try to get access the data

If sucess, I'll do a backup. You will not be in this situation if you
had one. Maybe there's a reason for not to have one.

If it doesn't work or after the backup, I will run the pvremove

(From man pvremove)
"pvremove wipes the label on a device so that LVM will no longer
recognise it as a physical volume."

Hope Tom may give his opinion to this too.
Regards
Luis
