Removing a disk from a logical volume

[raiden]

Guys,

Can anyone of you suggest how to remove a disk from a logical volume. I have just now added the disk to the volume group and extended a logical volume on it. But I have not yet extended the FS, so the disk has no FS.

Now I need to remove the disk. Please suggest what commans should i execute

Hi,

have a look at the man page of 'lvreduce'.
It's save to do that, in case you had not done a call to extendfs, yet.
But having a backup would make me more confident ....

lvreduce the logical volume then you remove the voulme group with vgreduce (vg##) and then pvremove to remove the disk.

Thanks,

I did lvreduce on the VG. Actually i was worried if this command could affect the LE's which had a FS. But it worked well.

lvreduce -l 8090 /dev/vgora4/lvol1
