Check the partition size on server
Dear All,


I need notification mail from server while device size crossed 80% approximately.I tried following shell .its working fine when the device name like /dev/sdc1 etc.Its not working in LVM name.For example

Script:

Code:
#!/bin/sh
echo "Storage server space details";
df -H | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print $5 " " $1 }' | while read output;
do
  echo $output
  usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1  )
  partition=$(echo $output | awk '{ print $2 }' )
  if [ $usep -ge 80 ]; then
    echo "Running out of space \"$partition ($usep%)\" on $(hostname) as on $(date)" |
     mail -s "Alert: Almost out of disk space $usep%" user1@domainname.com
  fi
done

----
>>Its working fine while following device name available

Code:
[root@Server1 test]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda6              95G  8.2G   82G  10% /
/dev/sda12            9.5G  3.5G  5.6G  39% /home

>> Its not working for like below mention name
Code:
#df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/device1/LVM_LGroup1
                      6.8G  791M  5.7G  13% /
/dev/sda1             996M   53M  892M   6% /boot
tmpfs                1006M     0 1006M   0% /dev/shm

pvck

PVCK(8) 						      System Manager's Manual							   PVCK(8)

NAME

       pvck - check physical volume metadata

SYNOPSIS

       pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

       pvck checks physical volume LVM metadata for consistency.

OPTIONS

       See lvm for common options.

       --labelsector sector
	      By  default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0.  This parameter allows you to specify a
	      different starting sector for the scan and is useful for recovery situations.  For example, suppose the partition table is corrupted
	      or  lost	on  /dev/sda, but you suspect there was an LVM partition at approximately 100 MB.  This area of the disk may be scanned by
	      using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):

	      pvck --labelsector 204800 /dev/sda

	      Note that a script can be used with --labelsector to automate the process of finding LVM labels.
