Well, yeah, I just wanted to make sure that removing the disk while some of its partitions are part of the LVM won't cause any problems. I can't remove it just yet anyway, the OS is also installed on other partitions on sda. So basically as long as I did a vgreduce, I can take the disk out, is that right? I am assuming /dev/sda4 is still showing in the pvdisplay output because it's still a LVM-type partition. > check /sys/block/sda/sda4/holders I did: root@neriak:/sys/block/sda/sda4/holders# l total 0 drwxr-xr-x 2 root root 0 2009-06-09 08:55 . drwxr-xr-x 4 root root 0 2009-06-09 08:43 .. lrwxrwxrwx 1 root root 0 2009-06-09 08:55 dm-1 -> ../../../../../../../../../virtual/block/dm-1 root@neriak:/sys/block/sda/sda4/holders# cd dm-1 root@neriak:/sys/block/sda/sda4/holders/dm-1# l total 0 drwxr-xr-x 5 root root 0 2009-06-09 08:43 . drwxr-xr-x 28 root root 0 2009-06-09 08:30 .. lrwxrwxrwx 1 root root 0 2009-06-09 08:55 bdi -> ../../bdi/252:1 -r--r--r-- 1 root root 4096 2009-06-09 08:55 capability -r--r--r-- 1 root root 4096 2009-06-09 08:55 dev -r--r--r-- 1 root root 4096 2009-06-09 08:55 ext_range drwxr-xr-x 2 root root 0 2009-06-09 08:55 holders drwxr-xr-x 2 root root 0 2009-06-09 08:55 power -r--r--r-- 1 root root 4096 2009-06-09 08:55 range -r--r--r-- 1 root root 4096 2009-06-09 08:55 removable -r--r--r-- 1 root root 4096 2009-06-09 08:55 ro -r--r--r-- 1 root root 4096 2009-06-09 08:55 size drwxr-xr-x 2 root root 0 2009-06-09 08:55 slaves -r--r--r-- 1 root root 4096 2009-06-09 08:55 stat lrwxrwxrwx 1 root root 0 2009-06-09 08:55 subsystem -> ../../../../class/block -rw-r--r-- 1 root root 4096 2009-06-09 08:43 uevent I have to admit I don't know what I am looking at.
