[linux-lvm] Has the failed drive been removed from the vg?



Hi,

I have a 1.5TB drive (/dev/sda) that failed but may have started failing over the the previous week (there was a point where the system did a fsck on the vg which I thought was related to the system rebooting after a power failure). I didn't notice anything untoward until today when I gather the drive finally failed.

The thing is that when I run the various commands, there is nothing to suggest that this drive is part of the vg yet I know it was

From the above I should be able to physically remove the drive and add a new one (to the VG) using the standard procedures?

Thanks in advance,
Jongi
