Hi, i ve setup a gluster mirror (2 machine runing debian jessie, and gluster rebuild from source 3.8.3-1). the undelying brick is on xfs filesystem (i ve mounted it with noattr2) i ve directories in gluster vols with posix acl : fine i share them with the native gluster NFS : fine if i set no_root_squash. if i set root squash : the nfs.log says : [2016-09-12 06:50:30.841786] W [MSGID: 114031] [client-rpc-fops.c:2930:client3_3_lookup_cbk] 0-vnas_gluster_users-client-1: remote operation failed.

But i need to use the gluster nfs as i want to use CTDB (from samba) too , in order to build a real active/active data cluster. Moreover i need to use root_squashing too because it will be the fileserver for all machine in the institute, so if someone with a linux laptop and root access can mount the nfs gluster homedirs it will have acces to all homedirs : no security... I ve not took the option nfs-ganesha as : i need to have NFS v3 with posix acl (old machines such as irix) A) Is there a way to increase the gluster nfs log verbosity ? b) i ve in the nfs.log a lot of : [2016-09-12 06:56:59.775860] E [MSGID: 112195] [nfs-fops.c:84:nfs_fix_groups] 0-nfs-server: getpwuid_r(118) found nothing The message "E [MSGID: 112195] [nfs-fops.c:84:nfs_fix_groups] 0-nfs-server: getpwuid_r(118) found nothing" repeated 74 times between [2016-09-12 06:56:59.775860] and [2016-09-12 06:57:16.373337] uid=118 is snmp ?Should i worry about it ? C) Is there another solution with this damned root_squash ? D) Am I totally insane to try this :): ?
