How do I remove a failed external disk.

[Betty Fessler]

How do I remove a failed external disk.
lvremove errors because the disk doesn't respond,
Can I just do a rename of /etc/lvmtab and then a vgscan -v. I don't intend to replace the failed disk.

Hi

If disk is mirrored then you don't have much problem.

This thread would give you more informations.

Hi,

1) If you are going to replace it and if the disk is a hot-swap, then replace it online and do a 'vgcfgrestore'

# vgcfgrestore -n vgname pvname

It is not a hot-swap disk, then shutdown the server and replace it. Then do the 'vgcfgrestore'

2) If you are not going to replace and not going to use that file systems, you can just do a 'vgexport'.

Hi,

If the disk is part of a volume group
you would need to run vgscan. If it
is in a group on it's own run the
vgexport command

# vgexport /dev/youvg

A really nice and sure way of removing it is as such .. (assuming you want to remove lvol1 in vg03 and that LV is mirrored).

# lvdisplay -v -k /dev/vg03/lvol1
==> The PV1 and PV2 column, instead of displaying the device path, it'll show the "disk-key" value (either 0 or 1).

# lvreduce -m 0 -k 1 /dev/vg03/lvol1
==> Now reduce it with the "disk-key" value. In this case it's 1.

# mv /etc/lvmtab /etc/lvmtab.org
# vgscan -v
# vgreduce -f vg03
==>f option force removal of missing PVs
