Hi Alasdair,
Thanks for the reply & the advise.
I have run each with 4 '-v' options. Log files are included.
They appear truncated - the important bit at the end is missing:-)
I assume you are missing the regular (stdout) output - The log files
were just the stderr part. Stdout included in this message (for
completeness).
But it looks like you have 15 PVs in the same VG and are maintaining
15 copies of the metadata which all have to be maintained in sync.
I have 15 metadata copies indeed. That may be a bit excessive... I'll
reduce their number.
However, I assume you'll agree with me that an algorithm doing O(n^3)
disk-IO where O(n) is possible, is really a bit too inefficient.
Rogier.
