<html><body><p><font size="1"> </font><br><br><font size="2">Hi, all, Mladen,</font><br><br><font size="2">(This is my first post to the GPFSug-discuss list. I am IBMer, am the IBM worldwide technical support Evangelist on Spectrum Scale/ESS. I am based in Florida. Apologies if my attachment URL is not permitted or if I did not reply properly to tie my reply to the original poster - pls let me know if there are more instructions or rules for using GPFSug-discuss (I could not find any such guidelines)).</font><br><br><font size="2">-------------</font><br><br><font size="2">Mladen, </font><br><br><font size="2">Increasing or changing inodes in a GPFS/Spectrum Scale file system can be done non-disruptively, within the boundaries of how GPFS / Spectrum Scale works.</font><br><br><font size="2">I wrote and delivered the following presentation on this topic back in 2013 in the GPFS V4.1 timeframe. While older IBM technologies SONAS/V7000 Unified are the reason the preso was written, and the commands shown are from those now-withdrawn products, the GPFS concepts involved as far as I know have not changed, and you can simply use the GPFS/Spectrum Scale equivalent commands such as </font><font size="2" face="Courier">mmcrfs, mmcrfileset, mmchfileset</font><font size="2">, etc to allocate, add, or change inodes non-disruptively, within the boundaries of how GPFS / Spectrum Scale works. There's lots of diagrams.</font><br><font size="2"> </font><br><font size="2">Here is a Box link to download this 8.7MB preso which anyone who has the link can use to download : </font><br><br><a href="https://ibm.box.com/shared/static/phn9dypcdbzyn2ei6hy2hc79lgmch904.ppt"><font size="2">https://ibm.box.com/shared/static/phn9dypcdbzyn2ei6hy2hc79lgmch904.ppt</font></a><br><br><font size="2">This should apply to any Spectrum Scale / GPFS file system this is the the Spectrum Scale V4.x or older format. I would imagine a file system with the newer Scale V5 variable sub-blocks has a modification to the above schema. I'd be interested to know what that is and how V5 users should modify the above diagrams/information.</font><br><br><font size="2">The PPT is handy because there is animation in Slideshow mode to better explain (at least in my mind) how GPFS / Spectrum Scale V4.x and older allocates inodes, and how you extend or under what circumstances you can change the number of inodes in either a file system or an independent file set.</font><br><br><br><font size="2">This Box link, will expire on Dec 31, 2019. If you are reading this post past that date, just email me and I will be happy to reshare the preso with you. </font><br><br><font size="2">I wrote this up because I myself needed to remember inode allocation especially in light of how GPFS independent filesets works, should I ever need to refer back to it. </font><br><br><font size="2">Happy to hear feedback on the above preso from all of you out there. Corrections/comments/update suggestions welcome. </font><br><br><br><font size="2" face="Arial">Regards,</font><br><br><b><font color="#888888" face="Arial">John M.
