Hello,
I am setting up a host with LVM volumes for each vserver.
I made scripts for vserver creation which include on-the-fly Logical Volume creation, formating and mount, that works pretty well.
Things are getting worse when I try to delete a Logical Volume after having the vserver stopped and its partition umounted:
I randomly get this error:
"Can't remove open logical volume"
Here are basic examples of the scripts:
CREATION
usage:
vcreate [name]
#!/bin/bash
lvcreate -L5000 -n"$1" vg0
mkreiserfs -f /dev/vg0/"$1"
mkdir /vservers/"$1"
mount /dev/vg0/"$1" /vservers/"$1"
vserver "$1" build -m skeleton
DELETION
usage:
vdelete [name]
#!/bin/bash
vserver "$1" stop
lsof /vservers/"$1"
umount -f /vservers/"$1"
lvremove -f /dev/vg0/"$1"
The Logical Volume seems actually umounted because cat /proc/mounts doesn't mention it, but *something* is still using it and I cannot figure out what.
A reboot of the host corrects the problem but I can't reboot the whole system each time I need to delete a vserver.
I have found a log chat at http://irc.13thfloor.at/LOG/2006-04/LOG_2006-04-22.txt where someone was experiencing exaclty the same problem but no solution was found at the moment.
Thanks in advance for any help or ideas!
Regards,
Mehdi Bennani
