openvz VM's very slow to start up

[peter]

I've just upgraded to PVE1.3 running on an IBM x3650.

The server boots up reasonably quickly, but the start up of each openvz host (via /etc/rc2.d/S20vz start_ is taking around 10 mins each. I notice the command it's running is vzquota, eg:

/usr/sbin/vzquota on 105 -r 0 -b 73400420 -B 80740452 -i 14000100 -I 15400100 -e 0 -n 0 -s 0

Doing a strace on that process shows it is busy doing something, but I have no idea why it's taking so long.

I set

DISK_QUOTA=no
VZFASTBOOT=yes

in /etc/vz/vz.conf and they all (8 VM's) came up in less than 60 secs.

I guess you have many small files inside the containers, so computing quotas takes long time.

 

[peter]

There's only one container that has a large number of files. All of the openvz containers are <100GB.

And that is CT 105?

CT105 is one of the smaller ones

# df -hi
Filesystem Inodes IUsed IFree IUse% Mounted on
simfs 104M 4.7M 99M 5% /
tmpfs 2.7M 2 2.7M 1% /lib/init/rw
tmpfs 2.7M 3 2.7M 1% /dev/shm

When DISK_QUOTA was set to 'yes', I gave up after about 15 mins waiting for it to start.
