Many thanks Herbert, you made my day.
Quota is working fine now.
Two little questions:
do I need to mount the lvm partition with quota support ?
=> mount -o rw,usrquota,grpquota /dev/vservers/vs1lv
When I do a "vserver vserver1 stop", I got an error :
Stopping the virtual server mserver1
Server mserver1 is running
ipv4root is now 192.168.100.64
New security context is 49152
Stopping MySQL: [ OK ]
Stopping httpd: [ OK ]
Turning off quotas: [ OK ]
Stopping sshd: [ OK ]
Stopping crond: [ OK ]
Saving random seed: [ OK ]
Shutting down system logger: [ OK ]
Starting killall: Turning off quotas: quotaoff: quotactl on /dev/hdv1 [/]:
No such process
quotaoff: quotactl on /dev/hdv1 [/]: No such process
[FAILED]
[FAILED]
sleeping 5 seconds
It seems that the redhat distrib (enterprise 2.1) shut down the quota first
and try to shut it down one more time at the end.
How to resolve this problem ?
have a very good day,
JC
