<font size="2" face="Tahoma">Hello,</font><br>
<font size="2" face="Tahoma">I've a Lenovo Spectrum Scale system DSS-G220 (software dss-g-2.0a) composed of</font><br>
<font size="2" face="Tahoma">2x x3560 M5 IO server nodes</font><br>
<font size="2" face="Tahoma">1x x3550 M5 client/support node</font><br>
<font size="2" face="Tahoma">2x disk enclosures D3284</font><br>
<font size="2" face="Tahoma">GPFS/GNR 4.2.3-7</font><br>
<br>
<font size="2" face="Tahoma">Can anybody tell me if it is normal that all the pdisks of both my recovery groups, residing on the same physical enclosure have free space equal to (more or less) 1/3 of the free space of the pdisks residing on the other physical
enclosure (see attached text files for the command line output) ?</font><br>
<br>
<font size="2" face="Tahoma">I guess when the least free disks are fully occupied (while the others are still partially free) write performance will drop by a factor of two. Correct ?
</font><br>
<font size="2" face="Tahoma">Is there a way (considering that the system is in production) to fix (rebalance) this free space among all pdisk of both enclosures ?</font><br>
<br>
<font size="2" face="Tahoma">Should I open a PMR to IBM ?</font><br>
<br>
<font size="2" face="Tahoma">Many thanks,</font><br>
