Removing LV with mirror

[Larry Scheetz]

I have two 18G drives mirrored (usable 9g). I want to remove lvol9 and lvol10 for there no longer needed. Is this as easy as using lvremove or is there other steps in this process since it is mirrored? Do I need to change anything else to make changes complete. Thank you for your time.

If you like, you can do an lvreduce to remove the mirror then do an lvremove.

[Patrick Wallek · Accepted solution]

After you do the lvreduce and lvremove, be sure to take the entries out of your /etc/fstab so the system doesn't try to mount those directories next time you reboot.

[S.K. Chan]

Just make sure the lvol9 and lvol10 are not NFS mounted before you do .. (assuming vg02)

# lvremove /dev/vg02/lvol9
# lvremove /dev/vg02/lvol10

Command will prompt for confirmation.
