[Users] trouble volume size (lvm) in host after stop ve

[Greg]

Hi, 

When i'm stop VE (were some mount with bind option), after ve stop,
host df commande report bad size for www & home ! (see size below)

i'll try both 202.umount & 202.stop batch without any change for volume
size after ve stopped 


Good size before ve stop :
-------------------------
# df -h | grep mnt | grep sata
                       10G  2,4G  7,7G  24% /mnt/satavol1/lvm-ftp
                       20G  8,7G   12G  44% /mnt/satavol1/lvm-www
                       80G   34G   47G  42% /mnt/satavol1/lvm-home

Bad size after ve stop (look the 1.9G instead more than 20G !!)
----------------------
vzctl stop 202 ; df -h | grep mnt | grep sata
umount external directory into vps
umount: /vz/root/202/home: not found
umount: /vz/root/202/var/www: not found
Stopping VE ...
VE was stopped
umount external directory into vps
VE is unmounted
                       10G  2,4G  7,7G  24% /mnt/satavol1/lvm-ftp
                      1,9G  243M  1,6G  14% /mnt/satavol1/lvm-www
                      1,9G  243M  1,6G  14% /mnt/satavol1/lvm-home

So i'll try umount the two wrong size volume :
# umount /mnt/satavol1/lvm-www ; umount /mnt/satavol1/lvm-home
umount: /dev/mapper/satavol1-lvm--www: not mounted
umount: /dev/mapper/satavol1-lvm--www: not mounted
umount: /dev/mapper/satavol1-lvm--home: not mounted
umount: /dev/mapper/satavol1-lvm--home: not mounted
# umount /mnt/satavol1/lvm-www ;  umount /mnt/satavol1/lvm-home
umount: /mnt/satavol1/lvm-www: not mounted
umount: /mnt/satavol1/lvm-home: not mounted

i mount the two volume
# mount /mnt/satavol1/lvm-www ; mount /mnt/satavol1/lvm-home

the two volume were had the good size back !:
#  df -h | grep mnt | grep sata
                       10G  2,4G  7,7G  24% /mnt/satavol1/lvm-ftp
                       20G  8,7G   12G  44% /mnt/satavol1/lvm-www
                       80G   34G   47G  42% /mnt/satavol1/lvm-home








# cd /etc/vz/conf ; for script in 202.mount 202.umount 202.stop ; do
echo ""; echo $script; echo "==========" ; cat $script | grep -v "^#" ;
done

202.mount
==========
echo " $0 mount external directory into vps"
mount  --bind /mnt/satavol1/lvm-home /vz/root/202/home
mount  --bind /mnt/satavol1/lvm-www  /vz/root/202/var/www

202.umount
==========


echo "umount external directory into vps"
umount  /vz/root/202/home
umount  /vz/root/202/var/www
exit 0

202.stop
==========


echo "umount external directory into vps"
umount  /vz/root/202/home
umount  /vz/root/202/var/www
exit 0
