Hi Fred,
thanks a lot for the hints. Hence, I'll try with 3WayReplication as this is the only raid code supporting 256KB, and data and metadata in the same pool (I guess is not worth to split it here). Thanks a lot for your help, Marc _________________________________________________________ Paul Scherrer Institut High Performance Computing & Emerging Technologies Marc Caubet Serrabou Building/Room: OHSA/014 Forschungsstrasse, 111 5232 Villigen PSI Switzerland Telephone: +41 56 310 46 67 E-Mail: [email protected] ________________________________ From: [email protected] <[email protected]> on behalf of Frederick Stock <[email protected]> Sent: Thursday, June 25, 2020 1:08:39 PM To: [email protected] Cc: [email protected] Subject: Re: [gpfsug-discuss] Dedicated filesystem for cesSharedRoot Generally these file systems are configured with a block size of 256KB. As for inodes I would not pre-allocate any and set the initial maximum size to value such as 5000 since it can be increased if necessary.

However, when reading the documentation (https://www.ibm.com/support/knowledgecenter/STXKQY_5.0.4/com.ibm.spectrum.scale.v5r04.doc/bl1adm_setcessharedroot.htm), is recommended (but not enforced) the use of a dedicated filesystem (of at least 4GB). Is there any best practice or recommendation for configuring this filesystem? This is: inode / block sizes, number of expected files in the filesystem, ideal size for this filesystem (from my understanding, 4GB should be enough, but I am not sure if there are conditions that would require a bigger one). Thanks a lot and best regards, Marc _________________________________________________________ Paul Scherrer Institut High Performance Computing & Emerging Technologies Marc Caubet Serrabou Building/Room: OHSA/014 Forschungsstrasse, 111 5232 Villigen PSI Switzerland Telephone: +41 56 310 46 67 E-Mail: [email protected] _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
