[LUDOC-74] Recreating the OST configuration files missing dd option

Tue, 2 Jul 2013 22:52:45 +0000

Section 14.7.3. Restoring OST Configuration Files part 4 is incorrect. The dd command given is:
dd if=/tmp/ldd of=/mnt/ost/CONFIGS/mountdata bs=4 count=1 seek=5 skip=5
and it should be
dd if=/tmp/ldd of=/mnt/ost/CONFIGS/mountdata bs=4 count=1 seek=5 skip=5 conv=notrunc

As Andreas Dilger says:
"It looks like the manual is missing one important option here. "dd" should be using "conv=notrunc" to avoid truncating the file."

It should be noted that without the correct instructions it is impossible to bring in a replacement OST when an OST has crashed.
