[Ocfs2-users] Centos 5.5 OCFS2: No space left on device

Hello!

I have frequently issue with "No space left on device" on LVM2 + DRBD +
OCFS2 while creating files ~10 MBytes in size.
This volume is used for WWW Apache cluster for sharing static (a lots of jpg
files) content between two nodes in Active/Active setup.

Is there some problems with my setup? Could anyone help me with this
problem?

There is some information:


mount:
/dev/drbd0 on /mnt/static type ocfs2
(rw,_netdev,noatime,nodiratime,heartbeat=local)

df -h:
Filesystem            Size  Used Avail Use% Mounted on
/dev/drbd0            201G  160G   42G  80% /mnt/static
