Hi all,
I'm testing IO performance.
My cluster consists of 4 nodes connect to 1 block-device using iSCSI-Multipath.
Block-device is formated in OCFS2 file system & mounted to nodes.
My first problem:
- If I use dd or iozone in single node => adapters network utilization in
storage ~ 80% - 90%
- Bu
oh crap. The dlm lock needs to lock the journals. So you need to recreate
the
journal inodes with i_size 0.
dd a good journal inode and edit it using binary editor. Change the inode
num
to the block number, zero out the i_size and next_free_extent. Repeat for
the
4 inodes.
Hopefully some one on t

The 4 journal inodes got zeroed out. Do you know how/why?
Have you tried running fsck with -fy (enable writes).
fsck.ocfs2 does have a check for bad journals that it will regenerate.
JOURNAL_FILE_INVALID
OCFS2 uses JDB for journalling and some journal files exist in the system
directory. Fsck ha
Hello,

thank for your
Hi all.
I have problem with performance ocfs2. I just instaled ocfs2 1.4.1 in 2

Ocfs2 is formated:
>> mkfs.ocfs2 -T mail -N 2 /dev/sdb1
mkfs.ocfs2 1.4.1
Cluster stack: classic o2cb

Use debugfs.ocfs2.
debugfs.ocfs2 /dev/hda6 will allow you to traverse the directories
on disk. Do the same on the both nodes. Is the information getting
flushed to disk?

Simply put, the device you are mounting is not an ocfs2 volume.
Use other tools to investigate.
