Dear Joel, I am using a custom compiled kernel version 2.6.32.2, using the
stock ubuntu 9.10 server-config for the kernel config.
r...@s2-replay01:~# uname -a
Linux s2-replay01 2.6.32.2.31337 #1 SMP Wed Dec 30 11:36:40 CST 2009 x86_64
GNU/Linux
r...@s2-replay01:~#
r...@s2-replay01:~# grep OCFS2 /usr/src/linux-2.6.32.2/.config
CONFIG_OCFS2_FS=m
CONFIG_OCFS2_FS_O2CB=m
CONFIG_OCFS2_FS_USERSPACE_CLUSTER=m
CONFIG_OCFS2_FS_STATS=y
CONFIG_OCFS2_DEBUG_MASKLOG=y
# CONFIG_OCFS2_DEBUG_FS is not set
CONFIG_OCFS2_FS_POSIX_ACL=y
r...@s2-replay01:~#
r...@s2-replay01:~# grep -i ocfs /proc/filesystems
nodev ocfs2_dlmfs
ocfs2
r...@s2-replay01:~#
the mkfs.ocfs2 does not throw an error. It did not throw an error on the ocfs2
1.4 modules downloaded for Redhat5 either. I've changed the OS to Ubuntu
because I was having all sorts of trouble getting a kernel to compile and boot
on CentOS. I'm a lot more comfortable in Debian/Ubuntu anyhow. I was hoping the
absolute newest kernel would fix this issue, but it did not. I have also
compiled the ocfs2-tools-1.4.3. It broke on fsck, but i was able to get the
mount.ocfs2 binary to compile. I again used the mount -o inode64 option with
the exact same errors as before. Appears it's still using JDB instead of JDB2.
Anything else I can give you to help debug?
