<span style=" font-size:10pt;font-family:sans-serif">Hello,</span><br><br><span style=" font-size:10pt;font-family:sans-serif">I have a Spectrum
Scale cluster with 10 nodes on the version 4.2.<br>The cluster have maxblocksize=DEFAULT.<br>I will migrate all nodes to 5.0.3 (online) none downtime.<br></span><br><span style=" font-size:10pt;font-family:sans-serif">But the maxblocksize
is fixed on the mmlsconfig after the migration (the man have this information)<br></span><br><span style=" font-size:10pt;font-family:sans-serif">maxblocksize 1M</span><br><br><span style=" font-size:10pt;font-family:sans-serif">man mmchconfig</span><br><span style=" font-size:10pt;font-family:sans-serif"><b>Note</b>: When
you migrate a cluster from an earlier version to 5.0.0 or later, the value
of maxblocksize stays the same. However, if maxblocksize was set to
DEFAULT in the earlier version of the cluster, then migrating it to 5.0.0
or later sets it explicitly to 1 MiB, which was the default value in earlier
versions. To change maxblocksize to the default value after migrating to
5.0.0 or later, set maxblocksize=DEFAULT (4 MiB).</span><br><br><span style=" font-size:10pt;font-family:sans-serif">How Can I perform
non-stop migration and after migration create a new filesystem with blocksize
= 4MiB?</span><br><br><span style=" font-size:10pt;font-family:sans-serif">My question is
about finishing the migration and create a new filesystem with block size
set to 4 MiB, its won't be possible until the maxblocksize changes.<br>In a environment where all migration will be done without stopping the
cluster, my question was if there was any alternative <br>This behavior forces the entire cluster to stop.</span><br><span style=" font-size:9pt;font-family:Arial"><br></span><table width=650 style="border-collapse:collapse;"><tr height=8><td width=384 style="border-style:none none none none;border-color:#000000;border-width:0px 0px 0px 0px;padding:0px 0px;"><span style=" font-size:9pt;font-family:Arial">Regards,</span><br><br><span style=" font-size:12pt;color:#8f8f8f;font-family:Arial"><b>Rafael
