Hello all. I think there's something wrong in the docs: the page https://docs.gluster.org/en/main/Administrator-Guide/Handling-of-users-with-many-groups/ says "The FUSE client gets the groups of the process that does the I/O by reading the information from /proc/$pid/status. This file only contains up to 32 groups." I checked on my system and status files report way more than 32 groups (when the user does have 'em, obv). It could probably just be outdated info: I think it got 'fixed' 9y ago by this patch: https://linux-kernel.vger.kernel.narkive.com/KDWSnAMn/patch-proc-pid-status-show-all-supplementary-groups -- Diego Zuccato DIFA - Dip. di Fisica e Astronomia Servizi Informatici Alma Mater Studiorum - Universit? di Bologna V.le Berti-Pichat 6/2 - 40127 Bologna - Italy tel.: +39 051 20 95786
