Which is: when some xattr does not exist on one copy but does on the other, like: 3]$ getfattr -d -m . -e hex .vim.backup/.bash_profile.swp # file: .vim.backup/.bash_profile.swp security.selinux=0x73797374656d5f753a6f626a6563745f723a756e6c6162656c65645f743a733000 trusted.afr.USER-HOME-client-0=0x000000010000000100000000 trusted.afr.USER-HOME-client-5=0x000000010000000100000000 2]$ getfattr -d -m . -e hex .vim.backup/.bash_profile.swp # file: .vim.backup/.bash_profile.swp security.selinux=0x73797374656d5f753a6f626a6563745f723a64656661756c745f743a733000 trusted.afr.USER-HOME-client-5=0x000000010000000100000000 trusted.afr.USER-HOME-client-6=0x000000010000000100000000 that means the file .bash_profile.swp is possibly in a data and metadata splitbrain I need to understand the volume configuration, that is the reason I am asking for volume info By seeing the above, I am guessing that it is a x3 volume(3 replica copies) unless the doc talks about it and I've gone (temporarily) blind, but if it's does not it would be great to include more scenarios/cases there. many thx.
