ocfs2 is a shared disk cluster file system. It requires a shared disk. However, if you are only going to use 2 nodes, you could use drbd, a replicating block device. To ocfs2, it appears as a shared disk. Google drbd and ocfs2 for more. On 10/05/2011 07:15 AM, Bradlee Landis wrote: > I have asked

Re: [Ocfs2-users] Unable to umount a filesystem - OCFS still thinks it has it mounted?‏

Check /proc/mounts. That's the kernels view of the mounts. mount looks at /etc/mtab. And ocfs2 1.2 adds and removes entries /proc/fs/ocfs2 during mount/umount. Also, see if there are relevant errors in dmesg. On 06/16/2011 07:16 PM, Neil Campbell wrote: Hi all, Not sure what has happened but

Upgrade to a more recent kernel (2.6.35+). Upgrade ocfs2-tools to 1.6.x. Run tunefs.ocfs2 and enable feature discontig-bg. This will address this issue. On 06/08/2011 02:16 PM, Osvaldo Alvarez Pozo wrote: > Hi > I can not copy files bigger than 4Mbytes! > I have an ocfs2 cluster with 4 nodes usin

Re: [Ocfs2-users] Large Files Hang Server

If your apps do not care about atime, then noatime is helpful. data=writeback should performs better than data=ordered. But there is a small chance that files having trailing nulls if a node were to reboot after a journal commit but before a data flush. This is documented in the manpages and the us

Your config is sufficient. Hard to say why it did not reboot. Ping the debian mailing list to see if there are reports of the same on whatever kernel you are on. As far as the reason for it goes, there should have been a message just prior to the Kernel Panic message. Most likely reason is that i
