Hi Bryan,
<div class=""><br class="">
</div>
<div class="">NO - it has the fix for the mmrestripefs data loss bug, but you need the efix on top of 4.2.3-4 for the mmadddisk / mmdeldisk issue.</div>
<div class=""><br class="">
</div>
<div class="">Let me take this opportunity to also explain a workaround that has worked for us so far for that issue … the basic problem is two-fold (on our cluster, at least). First, the /var/mmfs/gen/mmsdrfs file isn’t making it out to all nodes all the
time. That is simple enough to fix (mmrefresh -fa) and verify that it’s fixed (md5sum /var/mmfs/gen/mmsdrfs).</div>
<div class=""><br class="">
</div>
<div class="">Second, however - and this is the real problem … some nodes are never actually rereading that file and therefore have incorrect information *in memory*. This has been especially problematic for us as we are replacing a batch of 80 8 TB drives
with bad firmware. I am therefore deleting and subsequently recreating NSDs *with the same name*. If a client node still has the “old” information in memory then it unmounts the filesystem when I try to mmadddisk the new NSD.</div>
<div class=""><br class="">
</div>
<div class="">The workaround is to identify those nodes (mmfsadm dump nsd and grep for the identifier of the NSD(s) in question) and force them to reread the info (tsctl rereadnsd).</div>
<div class=""><br class="">
</div>
<div class="">HTH…</div>
<div class=""><br class="">

Hi All,<span class="apple-converted-space"> </span><br class="">
<br class="">
Does anybody know if GPFS 4.2.3.4, which came out today, contains all the patches that are in GPFS 4.2.3.3 efix3?<br class="">
<br class="">
If anybody does, and can respond, I’d greatly appreciate it. Our cluster is in a very, very bad state right now and we may need to just take it down and bring it back up. I was already planning on rolling out GPFS 4.2.3.3 efix 3 over the next few weeks anyway,
so if I can just go to 4.2.3.4 that would be great…<br class="">
<br class="">
Thanks!<br class="">
<br class="">
