<p class="MsoNormal"><span style="font-size:11.0pt">We recently upgraded our GL4 to a GL6 (trouble free process for those considering FYI). I now have 615T free (raw) in each of my recovery groups. I’d like to increase the size of one of the file systems (currently
at 660T, I’d like to add 100T).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">My first thought was going to be:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal">mmvdisk vdiskset define --vdisk-set fsdata1 --recovery-group rg_gssio1-hs,rg_gssio2-hs --set-size 50T --code 8+2p --block-size 4m --nsd-usage dataOnly --storage-pool data<o:p></o:p></p>
<p class="MsoNormal">mmvdisk vdiskset create --vdisk-set fs1data1 <o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">mmvdisk filesystem add --filesystem fs1
</span>--vdisk-set fs1data1 <span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I know in the past use of mixed size NSDs was frowned upon, not sure on the ESS.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The other approach would be add two larger NSDs (current ones are 330T) of 380T, migrate the data to the new ones using mmrestripe, then delete the old ones. The other benefit of this process would be to have
the file system data better balanced across all the storage enclosures.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Any considerations before I do this? Thoughts?<o:p></o:p></span></p>
