How about oflag=fsync? Your older systems should support that, I think.

You are welcome to add that option, but I think it is not available

Hi Bart,
Should that dd command in there have an extra flag like
"oflag=direct" to make sure it doesn't just write to the buffer
cache when you check the device? oflag=fsync would probably work too.

We have seen several cases where iSCSI errors have caused the
device
to become read-only while a file system server daemon is running.
This patch adds a check to the Filesystem-qla-monitor script
to make
sure the device is still writable and causes a STONITH if not.
Bart.
