Delayed updates to shared filesystem

I have installed Oracle RAC 11.2.0.3 and RDBMS 11.2.0.3 on a Oracle VM v4.2.4r81684 (all 64 bit). I have successfully created a RAC database across the nodes using vm disks. All seems good, but I added another disk and created an ext3 file system. All three machines can see the disk, but writes to the disk don’t appear until the next reboot. Any ideas?

--Commands used to create the disk
VBoxManage createhd filename asm-g1-10.vdi size 10240 format VDI variant Fixed
VBoxManage modifyhd asm-g1-10.vdi --type shareable
VBoxManage storageattach vbox1 storagectl "SATA" port 10 device 0 type hdd medium asm-g1-10.vdi mtype shareable
VBoxManage storageattach vbox2 storagectl "SATA" port 10 device 0 type hdd medium asm-g1-10.vdi mtype shareable
VBoxManage storageattach vbox3 storagectl "SATA" port 10 device 0 type hdd medium asm-g1-10.vdi mtype shareable

Fstab entry
/dev/sdk1 /common ext3 defaults 0 0


[root@vbox1 ~]# fdisk -l /dev/sdk
