I have installed Oracle RAC 18.104.22.168 and RDBMS 22.214.171.124 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
Really? You created an ext3 fs on a shared disk and mounted that on three different VMs? That simply won't work, since ext3 is not a shared fs. If you want to share disk storage between VMs than you have to go with OCFS2 as the file system.
