Hi Guys,
all in all ocfs2 is a nice piece of software and works very well. Last
week i made some benchmarks and was thinking if there is a way to make
it faster.
Here are some results perhaps someone can comment them:
XFS iSCSI target:
100MB/s block write
50MB/s block rewrite
140MB/s block
What features do you have enabled on disk?
debugfs.ocfs2 -R stats /dev/sdX
The disks were formated using max-features flag. The output looks like this:
Revision: 0.90
Mount Count: 0 Max Mount Count: 20
State: 0 Errors: 0
Check Interval: 0 Last Check: Wed
Hello All,
Is it normal to lose a shared node in OCFS shared servers? We have either lost
the whole ocfs mount point or lost mount point on one of the shared nodes
couple of times. Is this due to some misconfiguration?
Thanks,

HI,
here are all values. Just a side note all machines had a fresh reboot.
So these values are not right after the test.

Define lose?
Could it
It could be possible that it wasn't auto-mounted on reboot. Is there a separate
setting for that?

The user's guide explains all that.

Well the values during and after the test will give better info.
I will create a dedicated test setup and provide new values and stats.
BTW, how much memory do the nodes have?
Lock Resources: 1863 (497079)
This means that that node has created 497K lock resources
but have under 2000
