Description
mindi-2.0.7.3-0.20100407121858.rhel5
We have some servers running RedHat Cluster Suite and the pvscan's return an "unknown device" to stdout, not to stderr:
# pvscan 2>/dev/null PV /dev/emcpoweri1 VG vgbmr lvm2 [25.29 GB / 296.00 MB free] PV /dev/emcpowerh1 VG vgmbr lvm2 [505.75 GB / 505.75 GB free] PV /dev/cciss/c0d0p2 VG vgroot_xen lvm2 [132.42 GB / 88.92 GB free] PV /dev/emcpowerc VG xengfs lvm2 [505.75 GB / 0 free] PV /dev/emcpowero VG xengfs lvm2 [505.75 GB / 0 free] PV /dev/emcpowerg VG xengfs lvm2 [505.75 GB / 0 free] PV unknown device VG xengfs lvm2 [505.75 GB / 0 free] PV /dev/emcpowera VG xengfs lvm2 [505.75 GB / 0 free] PV /dev/emcpowerd VG xengfs lvm2 [505.75 GB / 12.00 MB free] Total: 9 [3.61 TB] / in use: 9 [3.61 TB] / in no VG: 0 [0 ]
This causes analyze-my-lvm to add a device called unknown to the lvm.res file:
/usr/sbin/lvmdiskscan /sbin/lvm i=2 LVM version >= 2.0 found. Just before you extrapolate mountlist to include RAID partitions, extrapolate it to include the following LVM drives and partitions:- >>>>> /dev/cciss/c0d0p2 unknown To get started, type:- (insmod dm-mod) (insmod dm_mod) # lvm vgchange -an # echo y | lvm pvcreate -ff /dev/cciss/c0d0p2 # echo y | lvm pvcreate -ff unknown # lvm vgscan . . .
I was able to fix the problem by filtering out the unknown devices in the ListAllPhysicalVolumes() function by grep'ing the output of the pvscan command and selecting only lines that don't match "unknown":
ListAllPhysicalVolumes() { if [ $lvmversion = 2 ]; then $LVMCMD pvscan 2> /dev/null | grep 'PV' | grep -v unknown | awk '{print $2}' > $MINDI_TMP/pv.tmp else pvscan 2> /dev/null | grep '"' | cut -d'"' -f2 > $MINDI_TMP/pv.tmp fi
The attached file has the change in it. Look for the line:
