[linux-lvm] Missing Logical Volumes

[G Crowe]

After rebooting, some of my logical volumes did not have device files.

/dev/array1/LVpics
and
/dev/mapper/array1-LVpics
did not exist but the output of "lvdisplay" said that the volume was 
available (see below).

vgscan did not resolve the problem.

I was able to regain access to the LV by renaming it, then renaming it 
back...
[root at host1 ~]# lvrename /dev/array1/LVpics /dev/array1/LVpicsnew
   Renamed "LVpics" to "LVpicsnew" in volume group "array1"
[root at host1 ~]# lvrename /dev/array1/LVpicsnew /dev/array1/LVpics
   Renamed "LVpicsnew" to "LVpics" in volume group "array1"

There are 29 LVs in the VG and 25 of them came up OK and 4 had this 
problem. Note that there is only one single PV (a RAID6 array) in the 
VG, and there are two VGs on the machine.

Is this expected behaviour, or is it something I should be worried about?
